AbstractHigh technology developments in diagnostic imaging raise a number of issues that are disturbing. New developments do not always favor greater diagnostic efficacy since fads, marketing promotion, and entrepreneurs can distort medical goals. New advances disseminate rapidly in affluent societies before formal benefit evaluations are completed. We suggest that digitization of radiography must be critically assessed, and simplicity of equipment design should be promoted. Though medical and economic factors can provide guidelines for policy making, the ultimate priority decisions are political in nature.

AbstractDiagnostic imaging in small hospitals is discussed. Four key questions are answered: (1) Are diagnostic imaging technologies necessary at this level? (2) Which technologies should be chosen and why? (3) How can they be most rationally and cost effectively used? (4) How can their total impact on health care be assessed? The paper concludes that small hospitals should have diagnostic imaging facilities and that the modalities of choice are diagnostic radiology and ultrasonography. A detailed description is given of the WHO Basic Radiological System and General Purpose Ultrasonographic equipment together with WHO recommendations for the rational use of diagnostic imaging.

Rapid diagnosis of suspicious pigmented skin lesions is imperative; however, current bedside skin imaging technologies are either limited in penetration depth or resolution. Combining imaging methods is therefore highly relevant for skin cancer diagnostics. This pilot study evaluated the ability of optical coherence tomography, reflectance confocal microscopy, photo-acoustic imaging and high-frequency ultrasound to differentiate malignant from benign pigmented skin lesions. A total of 41 pigmented skin tumours were scanned prior to excision. Morphological features and blood vessel characteristics were analysed with reflectance confocal microscopy, optical coherence tomography, high-frequency ultrasound and photoacoustic imaging images, and the diagnostic accuracy was assessed. Three novel photoacoustic imaging features, 7 reflectance confocal microscopy features, and 2 optical coherence tomography features were detected that had a high correlation with malignancy; diagnostic accuracy > 71%. No significant features were found in high-frequency ultrasound. In conclusion, optical coherence tomography, reflectance confocal microscopy and photoacoustic imaging in combination enable image-guided bedside evaluation of suspicious pigmented skin tumours. Combining these advanced techniques may enable more efficient diagnosis of skin cancer.

In this article we describe recent advances in imaging technologies that quantify the topography of the optic nerve head and retinal nerve fibre layer and their role in diagnosing glaucoma. These technologies include optical coherence tomography (OCT), scanning laser polarimetry (SLP, GDx) and confocal scanning laser ophthalmoscopy (CSLO, HRT). A review of recently published literature was carried out. The diagnostic performance of the different imaging devices is comparable and appears to be acceptable for the diagnosis of manifest glaucoma. The benefits of recent technological improvements need to be fully assessed. At the moment it is not clear which of the currently used imaging technologies is the most useful for diagnosis and management of glaucoma.

ABSTRACT Since, ultrasound was introduced as diagnostic tool in obstetrics and gynecology by Professor Ian Donald 6 decades ago, realtime imaging has become the most common sonographic technique used in obstetrics and gynecology. When uncertain findings on real-time gray scale during two-dimensional sonography require further evaluation, advanced techniques are often necessary. Such advanced techniques include color and power Doppler, three- and four-dimensional ultrasound and techniques of volume manipulation (rendering), such as surface and maximum mode, magic cut, volume calculation (VOCAL), NICHE mode, and -as latest innovation, HD flow (Doppler) and HD life surface rendering. The authors would like to illustrate by means of a series of images and case presentations, how these new diagnostic tools find their clinical application in the daily routine of care in obstetrics and gynecology.

Despite technical advances in many areas of diagnostic radiology, the detection and imaging of human cancer remains poor. A meaningful impact on cancer screening, staging, and treatment is unlikely to occur until the tumor-to-background ratio improves by three to four orders of magnitude (ie, 103- to 104-fold), which in turn will require proportional improvements in sensitivity and contrast agent targeting. This review analyzes the physics and chemistry of cancer imaging and highlights the fundamental principles underlying the detection of malignant cells within a background of normal cells. The use of various contrast agents and radiotracers for cancer imaging is reviewed, as are the current limitations of ultrasound, x-ray imaging, magnetic resonance imaging (MRI), single-photon emission computed tomography, positron emission tomography (PET), and optical imaging. Innovative technologies are emerging that hold great promise for patients, such as positron emission mammography of the breast and spectroscopy-enhanced colonoscopy for cancer screening, hyperpolarization MRI and time-of-flight PET for staging, and ion beam-induced PET scanning and near-infrared fluorescence-guided surgery for cancer treatment. This review explores these emerging technologies and considers their potential impact on clinical care. Finally, those cancers that are currently difficult to image and quantify, such as ovarian cancer and acute leukemia, are discussed.

ABSTRACT Implants improve the quality of life for patients who are unable to keep their natural teeth, fix acute problems, and give patients the benefit of restorative improvements for a modern lifestyle. The greatest key to successful implant placement is accurate preplacement assessment. Imaging plays a pivotal role in preplacement assessment. Success of dental implant restorations is in part, dependent on adequate diagnostic information about the bony structures of the oral region. This article reviews the applications of different imaging technologies and their diagnostic contribution to presurgical evaluation, treatment planning and postoperative assessment of dental implants.

Advanced ocular imaging technologies facilitate objective and reproducible quantification of change in glaucoma but at the same time, impose new challenges on scientists and clinicians for separating true structural change from imaging noise. This review examines time-domain and spectral-domain optical coherence tomography, confocal scanning laser ophthalmoscopy and scanning laser polarimetry technologies and discusses the diagnostic accuracy and the ability of each technique for evaluation of glaucomatous progression. A broad review of the current literature reveals that objective assessment of retinal nerve fiber layer, ganglion cell complex and optic nerve head topography may improve glaucoma monitoring when used as a complementary tool in conjunction with the clinical judgment of an expert.

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease of childhood and is characterized by an often insidious onset and a chronic relapsing–remitting course, once diagnosed. With successive flares of joint inflammation, joint damage accrues, often associated with pain and functional disability. The progressive nature and potential for chronic damage and disability caused by JIA emphasizes the critical need for a prompt and accurate diagnosis. This article provides a review of recent studies related to diagnosis, monitoring and management of JIA and outlines recent novel tools and techniques (infrared thermal imaging, three-dimensional imaging, accelerometry, artificial neural networks and fuzzy logic) which have demonstrated potential value in assessment and monitoring of JIA. The emergence of novel techniques to assist clinicians’ assessments for diagnosis and monitoring of JIA has demonstrated promise; however, further research is required to confirm their clinical utility.

The review presents an analysis of the literature on the diagnosis of gliomas and the study of their structural and biological features based on implementation of new techniques in clinical practice of diagnostic imaging. These techniques include perfusion technologies for multislice spiral computed tomography (MSCT), magnetic resonance imaging (MRI), functional MRI, proton magnetic resonance spectroscopy (MRS), single photon emission computed tomography (SPECT), and positron emission tomography (PET) with various radiopharmaceuticals (RPHs), first and foremost, labeled amino acids, such as11C-L-methionine and18F-Fluoroethyltyrosine. There is presented that with the application of these two methods (MRI and PET), the most important biochemical processes underlying oncogenesis of malignant tumors might be studied by non-invasive way. The obtained data can be crucial for an early detection of tumor lesions, staging the pathological process, rationale for therapeutic tactics, personalization of treatment, evaluation of the efficiency of therapy at early stages and prognosis of the disease result.

The cost-effectiveness and benefit of many diagnostic tests used in the presurgical evaluation for persons with epilepsy is for the most part uncertain as is their influence on decision-making. The options we have at our disposal are ever increasing. Advanced imaging modalities aim to improve surgical candidacy by helping us better define the epileptogenic zone and optimize surgical planning. However, judicious use is important. Randomized controlled trials delineating which mode of investigation is superior are lacking. Presurgical tests do have incremental value by increasing surgical candidacy and refining surgical planning. The yield of additional imaging will increase with complex localization. However, every case must be tailored by hypothesis, cost, and accessibility. Future studies using a quantitative cost–benefit framework are needed to determine the cost-effectiveness of advanced diagnostic tests (beyond magnetic resonance imaging) in the presurgical evaluation of those with epilepsy.

Biomedical optics is a broadly interdisciplinary field at the interface of optical engineering, biophysics, computer science, medicine, biology, and chemistry, helping us understand light–tissue interactions to create applications with diagnostic and therapeutic value in medicine. Implementation of biomedical optics tools and principles has had a notable scientific and clinical resurgence in recent years in the neurosurgical community. This is in great part due to work in fluorescence-guided surgery of brain tumors leading to reports of significant improvement in maximizing the rates of gross-total resection. Multiple additional optical technologies have been implemented clinically, including diffuse reflectance spectroscopy and imaging, optical coherence tomography, Raman spectroscopy and imaging, and advanced quantitative methods, including quantitative fluorescence and lifetime imaging. Here we present a clinically relevant and technologically informed overview and discussion of some of the major clinical implementations of optical technologies as intraoperative guidance tools in neurosurgery.

SummarySeveral studies have been carried out on vulnerable plaque as the main culprit for ischaemic cardiac events. Historically, the most important diagnostic technique for studying coronary atherosclerotic disease was to determine the residual luminal diameter by angiographic measurement of the stenosis. However, it has become clear that vulnerable plaque rupture as well as thrombosis, rather than stenosis, triggers most acute ischaemic events and that the quantification of risk based merely on severity of the arterial stenosis is not sufficient. In the last decades, substantial progresses have been made on optimisation of techniques detecting the arterial wall morphology, plaque composition and inflammation. To date, the use of a single technique is not recommended to precisely identify the progression of the atherosclerotic process in human beings. In contrast, the integration of data that can be derived from multiple methods might improve our knowledge about plaque destabilisation. The aim of this narrative review is to update evidence on the accuracy of the currently available non-invasive and invasive imaging techniques in identifying components and morphologic characteristics associated with coronary plaque vulnerability.

The diagnosis of pulmonary tuberculosis (PTB) in children is challenging. Difficulties in acquiring suitable specimens, pauci-bacillary load, and limitations of current diagnostic methods often make microbiological confirmation difficult. Chest imaging provides an additional diagnostic modality that is frequently used in clinical practice. Chest imaging can also provide insight into treatment response and identify development of disease complications. Despite widespread use, chest radiographs are usually non-specific and have high inter- and intra-observer variability. Other diagnostic imaging modalities such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) can provide additional information to substantiate diagnosis. In this review, we discuss the radiological features of PTB in each modality, highlighting the advantages and limitations of each. We also address newer imaging technologies and potential use.

Objectives: The aim of this study was to evaluate utilization trends of the diagnostic imaging examinations during the past decade in a university hospital in Turkey.Methods: Patient registries of a university hospital were used for the years 1995 and 2003. The data set consisted of patients' admissions, social security status, and diagnostic imaging tests.Results: When compared with 1995 data, the total number of diagnostic imaging examinations and patient admissions increased 65.9 percent and 81.6 percent, respectively, in the year 2003. Although the total number of diagnostic imaging tests decreased 9.0 percent, there was a 145.4 percent increase in magnetic resonance imaging (MRI) examinations. Nevertheless, radiological diagnostic procedures consisted of 12.8 percent of the total hospital revenues in 1995 and 9.4 percent in 2003.Conclusions: This study shows that approximately one third of inpatients underwent MRI and computed tomography examinations in 2003. The utilization rates of diagnostic imaging procedures, especially new technologies, need to be considered carefully with respect to appropriateness of procedures and planning of services.

Technological advancement, availability and common use of diagnostic imaging slowly but consistently leads to a change in its nature from being additional studies to becoming the basis for diagnostic process and treatment planning especially in complex cases that require surgical treatment. CT angiography study presentation using the illusion called "Pepper’s Ghost" in comparison to a three-dimensional printout and regular CT scan has been made to point out the relevance of research and implementation of new technologies in the diagnosis and surgical planning. Our image, despite being far from ideal and being just an illusion of a hologram, was more appealing and detailed to surgeons in comparison to a printed 3D model and standard CT angiography displayed with Osirix software. In order to change the existing methods of presenting imaging studies, it is advisable to use latest technologies, and among those currently available, ones based on virtual or mixed reality deserve special attention.

The clinical utility of a biomarker depends on its ability to identify high-risk individuals to optimally manage the patient. A new biomarker would be of clinical value if it is accurate and reliable, provides good sensitivity and specificity, and is available for widespread application. Data are accumulating on the potential clinical utility of integrating imaging technologies and circulating biomarkers for the identification of vulnerable (high-risk) cardiovascular patients. A multi-biomarker strategy consisting of markers of inflammation, hemostasis and thrombosis, proteolysis and oxidative stress, combined with new imaging modalities (optical coherence tomography, virtual histology plus IVUS, PET) can increase our ability to identify such thombosis-prone patients. In an ideal scenario, cardiovascular biomarkers and imaging combined will provide a better diagnostic tool to identify high-risk individuals and also more efficient methods for effective therapies to reduce such cardiovascular risk. However, additional studies are required in order to show that this approach can contribute to improved diagnostic and therapeutic of atherosclerotic disease.

The objective of this study was to identify the diagnostic capability of photostimulable phosphor plates (PSPs) and direct digital sensors (DDSs) in the detection of interproximal caries. Studies were identified that evaluated the diagnostic capability of PSPs and DDSs in detecting interproximal caries in human teeth, in both dentin and enamel. Histologic sections were the gold standard. This systematic review searched several electronic databases. In addition, Google Scholar and reference lists of the finally included studies were screened. QUADAS-2 was applied to evaluate the risk of bias among included studies. Six studies were finally included; 4 of which were considered homogeneous enough to conduct a meta-analysis. The meta-analysis evaluated 668 interproximal human tooth surfaces. All studies used extracted human teeth ranging from no caries present to caries into dentin. Each tooth was radiographed by both PSP and DDS technologies and then submitted for histologic analysis as the gold standard. Meta-analysis showed that intraoral digital imaging is of high specificity but low sensitivity in the detection of interproximal caries. The sensitivity and specificity for different studies with PSPs varied substantially from 15% to 54% and from 84% to 100%, respectively. Direct sensor analysis sensitivity and specificity ranged from 16% to 56% and from 90% to 100%, respectively. Newer PSP and DDS technologies had statistically significant higher sensitivities, yet the differences in diagnostic capabilities between the older and newer technologies were clinically insignificant. Both digital systems were excellent in identifying surfaces without caries (specificity) but were not sensitive enough to reliably identify interproximal surfaces with caries. Clinicians must therefore remain vigilant in performing a careful clinical examination and other diagnostic tests rather than relying solely on radiographic imaging to diagnose interproximal caries. Knowledge Transfer Statement: This study will help clinicians make an evidence-based decision when deciding which digital radiography system to use when evaluating interproximal caries. Time, patient radiation safety, cost, and image quality are factors to be considered. The performance of the different available digital imaging systems was compared with the current gold standard—a histologic analysis—via meta-analysis.

Fetal, perinatal, and neonatal asphyxia are vital health issues for the most vulnerable groups in human beings, including fetuses, newborns, and infants. Severe reduction in oxygen and blood supply to the fetal brain can cause hypoxic-ischemic encephalopathy (HIE), leading to long-term neurological disorders, including mental impairment and cerebral palsy. Such neurological disorders are major healthcare concerns. Therefore, there has been a continuous effort to develop clinically useful diagnostic tools for accurately and quantitatively measuring and monitoring blood and oxygen supply to the fetal and neonatal brain to avoid severe consequences of asphyxia HIE and neonatal encephalopathy. Major diagnostic technologies used for this purpose include fetal heart rate monitoring, fetus scalp blood sampling, ultrasound imaging, magnetic resonance imaging, X-ray computed tomography, and nuclear medicine. In addition, given the limitations and shortcomings of traditional diagnostic methods, emerging technologies such as near-infrared spectroscopy and photoacoustic imaging have also been introduced as stand-alone or complementary solutions to address this critical gap in fetal and neonatal care. This review provides a thorough overview of the traditional and emerging technologies for monitoring fetal and neonatal brain oxygenation status and describes their clinical utility, performance, advantages, and disadvantages.

Global statistics have demonstrated that breast cancer is the most frequently diagnosed invasive cancer and the leading cause of cancer death among female patients. Survival following a diagnosis of breast cancer is grossly determined by the stage of the disease at the time of initial diagnosis, highlighting the importance of early detection. Improving early diagnosis will require a multi-faceted approach to optimizing the use of currently available imaging modalities and investigating new methods of detection. The application of microwave technologies in medical diagnostics is an emerging field of research, with breast cancer detection seeing the most significant progress in the last twenty years. In this review, the application of current conventional imaging modalities is discussed, and recurrent shortcomings highlighted. Microwave imaging is rapid and inexpensive. If the preliminary results of its diagnostic capacity are substantiated, microwave technology may offer a non-ionizing, non-invasive, and painless adjunct or stand-alone modality that could possibly be implemented in routine diagnostic breast care.

Atherosclerosis complications such as myocardial infarction or stroke is still one of the most critical causes of death worldwide. Advance and innovative diagnostic technologies are urgently required to discover an early stage of the disease, such as plaque instability and thrombosis. A combination of molecular imaging probes based on well-designed nanomaterials with leading-edge imaging methods is currently concreting the direction for novel and distinctive approaches to examine the inflammatory growth in atherosclerosis. Over the past several decades, an exceptional understanding of the biological nature of atherosclerosis provides unique opportunities to better treat atherosclerotic disease with targeted imaging and nanomedicines. Consequently, tremendous development has been initiated in the nanotechnology application; the leading engineering tools working at molecular range, which is designed for diagnostic and therapeutic approach, called theranostic. This review underlying ideas involving the potential and development of molecular imaging technologies that had been invented for studying atherosclerosis. We envisage that many molecular imaging methods will become valuable assistants to the clinical management of targeted treatment in the atherosclerosis disease together with their challenges and future perspective in clinical translation.

The diagnostic approach to the biliary tree disorders can be challenging, especially for biliary strictures. Albeit the great diagnostic impact of endoscopic retrograde cholangiopancreatography (ERCP) which allows one to obtain fluoroscopic imaging and tissue sampling through brush cytology and/or forceps biopsy, a considerable proportion of cases remain indeterminate, leading to the risk of under/over treated patients. In the last two decades, several endoscopic techniques have been introduced in clinical practice, shrinking cases of uncertainties and improving diagnostic accuracy. The aim of this review is to discuss recent advances and emerging technologies applied to the management of biliary tree disorders through peroral endoscopy procedures.

Monostotic fibrous dysplasia is a benign asymptomatic lesion that affects only one bone, which is replaced by amorphous connective tissue. Clinically there is an increase in the volume of the affected area, which is observed by imaging as a radiopaque area with diffuse non-corticalized limits capable of expanding to neighboring structures, and it is histologically evidenced as “resembling Chinese characters”. The lesion is seen as a radiopaque image with diffuse borders in conventional or digital radiography, while cone beam computed tomography identifies the exact location and extension of an isodense, mixed or hyperdense image of non-corticalized edges. Magnetic resonance imaging is also used when the lesion involves soft tissues or nerves, and bone scintigraphy is performed in order to systemically observe bone quality. The objective of this article was to describe the new technologies in oral radiology for the diagnosis of monostotic fibrous dysplasia and the importance of the current imaging methods in achieving an adequate diagnosis. These techniques range from conventional radiography to bone scans, which provide images of higher quality, clarity and better precision with less invasive techniques to the patient. This review of the literature helps to expand the knowledge of dental professionals in relation to the clinical and imaging characteristics of monostotic fibrous dysplasia.

This paper is aimed to study abilities of new imaging methods for differentiating diffuse interstitial lung diseases. We analyzed radiological and CT findings of 301 patients with various diffuse lung pathologies. The investigation was performed as a slice spiral scanning and multi-plane spatial reconstruction modes. We modified a respiratory test for those patients who find difficulty in holding their breathing. To assess an informative value of a sign we evaluated its sensitivity, specificity, diagnostic accuracy, and predictive positive and negative tests. The article presents HRCT findings in various idiopathic interstitial lung diseases and differential criteria to distinguish those from other forms of diffuse lung diseases.

There are several unique features of the concept of advanced intraoperative imaging modalities with CT (computed tomography), MRI (magnet resonance imaging) and DSA (digital substraction angiography) inaugurated in one operating tract. For the first time, there is the opportunity to switch from postoperative to intraoperative imaging – when the surgeon can not only check the result of surgery but improve it – but in general, that is, for all specialties, at least theoretically. Intraoperative imaging is a broad term with many technologies already in routine use today, such as image intensifier, ultrasound, fluorescence technologies, and soon. Using intra-operative CT, MRI, and DSA is not indisputable. Does the benefit justify such immense costs, both in building and in maintenance? To evaluate the clinical benefit and possible drawbacks of these technologies and if there's a substantial benefit for the patients. Also, this is a review of literature to evaluate the evidence and clinical impact of advanced intraoperative imaging in neurosurgery. There is one prospective randomized trial showing that intraoperative MRI increases the extent of resection. In spine surgery, there are several randomized trials showing that pedicle screws are inserted more accurately when image guidance is used. However, there is no RCT comparing navigation with intraoperative CT-updated navigation. Several prospective studies are showing that intraoperative DSA is able to identify vascular remnants or vessel occlusions in case of aneurysm-, arteriovenous malformation-and arteriovenous fistula-surgery. A fair comparison of the benefit of these new technologies must take into consideration that other methods of intraoperative imaging or image guidance already exist. Hence, there are some patients in whom the use of the more advanced technologies makes a personal, individual difference that may affect quality of life and survival. We have to differentiate between (1) the best diagnostic procedure and (2) the term “standard of care.” Advanced intraoperative imaging is a gold standard in terms of imaging but not a standard of care.

Diagnostic systematic review is a vital step in the evaluation of diagnostic technologies. In many applications, it involves pooling pairs of sensitivity and specificity of a dichotomized diagnostic test from multiple studies. We propose a composite likelihood (CL) method for bivariate meta-analysis in diagnostic systematic reviews. This method provides an alternative way to make inference on diagnostic measures such as sensitivity, specificity, likelihood ratios, and diagnostic odds ratio. Its main advantages over the standard likelihood method are the avoidance of the nonconvergence problem, which is nontrivial when the number of studies is relatively small, the computational simplicity, and some robustness to model misspecifications. Simulation studies show that the CL method maintains high relative efficiency compared to that of the standard likelihood method. We illustrate our method in a diagnostic review of the performance of contemporary diagnostic imaging technologies for detecting metastases in patients with melanoma.
