Full textThere are two Gadolinium-based liver-specific contrast media for Magnetic Resonance Imaging on the market, Gd-BOPTA (MultiHance®, Bracco Imaging, Milan, Italy) and Gd-EOB-DTPA (Primovist®, Bayer Schering Pharma, Berlin, Germany). The aim of this study in two parts was to evaluate the dynamics of biliary, parenchymal and vascular enhancement using these contrast media in healthy subjects. Ten healthy volunteers were examined in a 1.5 T magnetic resonance system using three-dimensional Volumetric Interpolated Breath-Hold (VIBE) sequences for dynamic imaging with both contrast media – at two different occasions – until five hours after injection. The doses given were 0.025 mmol/kg for Gd-EOB-DTPA and 0.1 mmol/kg for Gd-BOPTA. The enhancement over time of the common biliary duct in contrast to the liver parenchyma was analyzed in the first study. This was followed by a study of the image contrasts of the hepatic artery, portal vein and middle hepatic vein versus the liver parenchyma.While Gd-EOB-DTPA gave an earlier and more prolonged enhancement of the biliary duct, Gd-BOPTA achieved higher image contrast for all vessels studied, during the arterial and portal venous phases. There was no significant difference in the maximal enhancement obtained in the liver parenchyma.At the obtained time-points and at the dosage used, the high contrast between the common biliary duct and liver parenchyma had an earlier onset and longer duration for Gd-EOB-DTPA, while Gd-BOPTA achieved higher maximal enhancement of the hepatic artery, portal vein and middle hepatic vein than Gd-EOB-DTPA. Diseases of the liver and biliary system may affect the vasculature, parenchyma, biliary excretion or a combination of these. The clinical context regarding the relative importance of vascular, hepatic parenchymal and biliary processes should determine the choice of contrast media for each patient and examination.

Full textThe background to the study was Unified Communications (UC), defined as Communications integrated to optimize business processes. A case study design is used to develop a LoFi-prototype. The prototype investigateswhat components an integrated communication solution should provide,for the people in radiology. The design was inspired by consumer products likeSkype. In these consumer products were functionality and look studied. The reason for integrate it into Sectra MEI, was that Sectra believed the system’s features could be even more useful, when used together with a communication solution. The prototype is tested on users (usability tested). To bundle the growing pile of requirements in the design process was a requirement specification produced.

Full textbodies, and narrative free text reports describing the findings in these visualizations are written by medical doctors. The information within these narrative reports is required to be extracted for medical information systems. Turkish is an highly agglutinative language and this poses problems in information retrieval and extraction from Turkish free texts. In this thesis one rule-based and one data-driven alternate methods for information retrieval and structured information extraction from Turkish radiology reports are presented. Contrary to previous studies in medical NLP systems, both of these methods do not utilize any medical lexicon or ontology. Information extraction is performed on the level of extracting medically related phrases from the sentence. The aim is to measure baseline performance Turkish language can provide for medical information extraction and retrieval, in isolation of other factors.

Resumo: O objetivo deste estudo foi avaliar a articulacao temporomandibular (ATM) de individuos portadores de Depressao Maior. A amostra foi constituida por 40 individuos diagnosticados por um medico psiquiatra, como portadores de Depressao Maior, segundo as diretrizes do DSM-IV (Manual de Diagnostico e Estatistica das Perturbacoes Mentais). Estes foram submetidos a exames clinicos e por imagem, que se constituiu de Ressonância Magnetica. Pela analise dos resultados, observou-se em relacao aos dados da anamnese, que a presenca da cefaleia recorrente foi a alteracao mais relatada, sendo citada como sempre presente (52,5% dos individuos) e ocasionalmente presente (47,5% destes). Em relacao ao exame clinico, a presenca de trajetoria mandibular alterada ocorreu em 85% dos individuos, sendo que 62,5% destes apresentaram desvio e 22,5% deflexao. Ruido articular, ocorreu em 70% das articulacoes (69% destas sendo estalido). Dor a funcao articular foi o sintoma mais observado, ocorrendo em 61,25% das articulacoes. No exame por imagem, o deslocamento de disco ocorreu em 54 articulacoes (67,5% da amostra), sendo o deslocamento sem reducao observado em 5 articulacoes (6,25%). Alteracao na posicao da cabeca da mandibula foi observada em 57 articulacoes (71,25% da amostra), sendo o posicionamento posterior o mais frequente, ocorrendo em 43 articulacoes (53,75%). Mobilidade anormal da cabeca da mandibula foi observada em 58 articulacoes (52 destas apresentaram hipermobilidade) (65%). Utilizando-se o Teste Exato de Fisher e o Teste do ?2 como analises estatisticas, observou-se nao haver relacao entre posicao do disco e dor a funcao da articulacao (p=0,34); entre funcao do disco e dor a funcao da articulacao (p=0,32); entre posicao do disco e dor muscular (p=0,40); entre funcao do disco e dor muscular (p=0,42) e entre posicao do disco e posicao da cabeca da mandibula (p=0,30). Verificou-se haver relacao entre posicao do disco e ruidos articulares (p=0,00) e entre posicao do disco e trajetoria mandibular (p=0,00). Somente um individuo apresentou dor, ruido articular e limitacao de movimentos da mandibula, sendo que este apresentava deslocamento de disco. Concluiu-se desta forma que, na amostra avaliada, a presenca de depressao maior nao foi um fator desencadeante para a desordem temporomandibular
Abstract: The aim of this study was to evaluate the temporomandibular joint (TMJ) of individuals with Major Depression. The sample comprised 40 individuals who were previously diagnosised as Major Depressed patients by a psychiatrist, using the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders). The subjects were submitted to clinical and imaging examination, which comprised TMJ magnetic resonance imaging. The result analysis showed that the headache was related as always present (52.5% of the individuals) or frequently present (47.5% of the individuals). With regard to clinical exam, the altered mandibular pathway occurred in 85% of the individuals, with 62.5% presenting deviation and 22.5% deflection. The joint noise occurred in 70% of the joints (69% cliking). Joint functional pain was the most frequent symptom observed, occurring in 61.25% of the joints. In the imaging exams, the disc displacement occurred in 54 joints (67.5% of the sample) the disc displacement without reduction was observed in 5 TMJ (6.25%). The mandibular condyle position was altered in 57 joints (71.25% of the sample) and the most frequent position observed was the posterior position (43 TMJ) (53.75%). Abnormal mandibular condyle mobility was observed in 58 joints (52 of then with hipermobility) (65%). Application of the Fisher¿s Exact Test and ?2 Test as statistical analysis revealed no relationship between disc position and joint functional pain (p=0.34);disc function and joint functional pain (p=0.32); disc position and muscle pain (p=0.40); disc function and muscle pain (p=0.42) and disc position and mandibular condyle position (p=0.30). A relationship was observed between disc position and joint noise (p=0.00) and between disc position and mandibular pathway (p=0.00). Only one individual reported pain, joint noise and limited mandibular movement, and this one presented disc displacement. Thus, it was concluded that the Major Depression presence was not an important appearance factor for the temporomandibular disorder, in this sample

Full textHereditary myopathies are diseases with a complex diagnosis. They may present with different phenotypes of muscle weakness. A relatively new phenotype is the axial phenotype. Adult Pompe’s disease (PD) is a glycogenosis. Glycogen accumulation in lysosomes causes muscle weakness that usually involves girdles and axial muscles associated with respiratory insufficiency. Myopathies due to mutations in EMD and LMNA genes may present with girdles weakness or with Emery-Dreifuss muscular dystrophy phenotype (EDMD). EDMD patients present a scapular-humeral-peroneal weakness associated with joint contractures at elbows, ankles and spine. In recent years computed tomography (CT) and magnetic resonance imaging (MRI) are being used for the study of some neuromuscular diseases. The hypothesis of this thesis is that muscular imaging could be a good diagnosis biomarker of Adult PD and EMD o LMNA genes related myopathy. A characteristic radiological pattern would allow an effective and early diagnosis. Aims were: 1) to describe the pattern of fatty muscle infiltration in these myopathies. 2) to study muscle infiltration in the paravertebral and abdominal area in 30 patients with PD. 3) to correlate muscle weakness with the degree of muscle infiltration in radiology in PD. 4) To describe clinical and radiological characteristics in 42 patients with mutations in EMD and LMNA genes. 5) to search radiological differences according to genotype (EMD o LMNA). PD study was performed in 30 patients with MRI or CT at the trunk level. We found that asymptomatic patients had fatty muscle infiltration in at least one muscle. There was a specific infiltration pattern in trunk area. Moreover this pattern makes evolves according to the clinical severity. There was a correlation between the degree of muscle infiltration and clinical stage. The study of myopathies due to mutations in EMD and LMNA genes was perfomed in 42 patients with MRI or CT of trunk and lower extremities area. We found EDMD patients showed no clinical differences according genotype. We described an infiltration pattern in these patients that affects paravertebral area, anterior and posterior compartment in the thigh and posterior compartment in the leg. Significative difference was found in the degree and frequency of infiltration in peroneal muscle. Peroneal Infiltration was greater in patients with mutations in EMD gene. We showed paravertebral infiltration in asymptomatic patients. We found an evolutive radiological pattern according to the clinical stage evolution. In conclusion muscular radiology is an effective biomarker for the diagnosis of adult PD and myopathies caused by mutations in the LMNA or EMD genes. In patients who share the same phenotype muscle imaging could be a useful tool to guide genetics studies.

Full textShared leadership paradigms are becoming more popular in organizations because of the increased responsibilities placed on leaders within health care organizations. Researchers have conducted little research on how individuals on leadership teams perceive their role in engaging with others in their team. The qualitative phenomenological hermeneutic study involved examining how radiology administrators in Northern California describe their lived experiences on shared leadership teams, with an emphasis on their perceptions of team productivity and trust. The conceptual framework for the study included shared leadership theory, which scholars have noted is still a new field of study. Seven research participants representing from three to 18 years of experience as radiology managers with experience serving on shared leadership teams. From the five initial questions and sub questions, the analysis involved breaking down the responses into 175 separate areas of exploration. In addition to the demographics of the groups and types of teams served on, four themes emerged from this data: lived experience on shared leadership teams, knowledge and skills learned from shared leadership teams, key factors affecting team performance on shared leadership teams, and the effect of diversity on shared leadership teams. The implications of the research to leadership are that radiology managers may gain a better understanding of when to use shared leadership and how to best staff the teams to support organizational work, and how to improve shared leadership team dynamics.

Full textThis study allowed the standardization of the bone mineral density (BMD) of the distal extremity of the radio of 36 dogs adults in Rottweiler breed by radiographic optic densitometry. The limbs of the animals were radiographed with scale of aluminum that served as a reference. The radiographies images were digitalized and analyzed by a computer program for comparison of gray tones between the standard image and the image of the reference scale radiographed with the bone. Afterwards the values of density were expressed in millimeters of aluminum. Also studied the correlations between BMD and the sex, weight and external measures as the length of spine, height of the animal and circumference the distal extremity of the limb in study. The mean values and standard deviations of the bone mineral density of the distal extremity of the radio were: for the metaphysary region the average of BMD of 7,88 ± 0,89 mmAl, the diaphysary region 1 the average of BMD of 8,58 ± 0,80 mmAl and for diaphysary region 2 of BMD of 9,00 ± 0,74 mmAl.

Full textEmbolization is an increasing part of the activity of endovascular interventional radiology. Embolization agents are numerous, have variable properties and make it possible to obtain a hemostasis, a hemodiversion, or achieve the vector of a targeted therapy. Our work is divided into three parts, successively aimed at a state of the art of available embolization agents, then original laboratory work, and finally the retrospective analysis of various radio-clinical studies made in our research center. The first part based on an analysis of the literature constitutes an introductory chapter in which the technical characteristics, the advantages and the limits of the embolization agents used in current clinical practice are assessed. The second part is based on fundamental animal studies carried out in the experimental catheterization laboratory of ISIT (Professors Boyer and Lusson) at the Faculty of Medicine of Clermont-Ferrand, and in the laboratory of endovascular biomaterials of the university. of Montreal (Professor Lerouge and Soulez). In a first series of experiments, in Montreal, we participated in the development of an embolization agent that combines the advantages of a gel (solidification in contact with blood) and a sclerosant (destruction of endothelial cells). The gel thus developed has been the subject of a patent application. It may be able to prevent and / or treat the leaks observed in stent-graft treatment of aortic aneurysms. In a second experimental protocol, in Clermont-Ferrand, we analyzed the interaction between embolization agent and chemotherapy by studying the pharmacokinetic changes observed according to the route of administration and the association with partial or complete embolization of the hepatic artery on a porcine model. The third part is based on original clinical work analyzing retrospectively various sensitive points in parenchymal embolization. This part is based on strong multidisciplinary collaborations in gynecological, urological, hepatic and splenic pathologies. Finally, it is necessary to announce the publication scheduled for the first quarter of 2012 of the book "Embolisation" (350 pages, Springer Ed., P. Chabrot and L. Boyer). An English version of this book will follow in the course of 2012

Full textThis work performed at the Institute of Mathematics of Bordeaux (IMB) from 2010 to 2015 under the direction of Thierry Colin and Olivier Saut describes the creation and gradual development of a set of theories, techniques and tools linking medical imaging and applied mathematics in order to consider their clinical application in the short term in oncology. The first goal was to optimize the spatial models of tumor growth developed at the IMB including microscopic and macroscopic elements obtained by analyzing the information available on imaging explorations. Several steps were performed to better understand the in vivo modeling. Various organs and tumor types were investigated, especially in the lung, liver, and kidney. These locations were studied successively to progressively enrich the model by the answers they brought and thus respond to clinical reality. Concomitantly, tools were integrated to standardize the data collection process and help to refine the therapeutic evaluation by imaging with digital markers. The implementation of functional imaging in clinical practice has become a reality. The goal is ultimately to apply prospectively these support tools in a daily practice. Modelling was also applied in interventional oncology for the study of the electric field distribution after percutaneous irreversible electroporation in the prostate and soon in the liver. This will allow a better control of the ablation areas and thereby improve the safety and efficacy of these treatments

Infobroker is an application developed by MawellSvenska AB that connects RIS and PACS to achieve interoperability by enablingimage and journal data transmission between radiology sites. To put the project in context, the field of medical informatics, RIS and PACS systems and common protocols and standards are explored. A proof-of-concept implementation of the proposed design shows its potential and verifies that it works. The thesis concludes that a more specialized approach is preferred.

Full textA ampla adoção de imagens médicas em formato digital nos diversos tipos de instituições de saúde, levantou novos problemas ao nível da gestão de dados e processos. A normalização destes cenários tem sido alvo de atenção nas últimas décadas, esforço que resultou no desenvolvimento e dinamização de normas como DICOM e HL7. Atualmente coexistem dois tipos de sistemas de informação num laboratório de imagem médica que devem funcionar de forma integrada, os RIS que são responsáveis pela gestão das tarefas administrativas e os PACS que fazem a gestão das imagens e informação associada. Esta dissertação teve como objetivo desenhar e implementar uma solução RIS baseada em ferramentas de utilização livre ou código aberto. Assim, começamos por estudar detalhadamente o estado da arte, incluindo soluções do domínio público e proprietárias, destacando os pontos fortes e fraquezas de cada uma. Para além da análise das tecnologias utilizadas no desenvolvimento de cada solução, este estudo teve contributos determinantes na análise de requisitos efetuada. Nomeadamente, permitiu-nos identificar funcionalidades inovadoras e com elevado valor para os utilizadores. O resultado é um sistema de informação capaz de gerir todas as operações de um departamento de radiologia, incluindo gestão administrativa de utentes, agendamento de exames, realização de relatórios clínicos, entre outras. Em termos de características inovadoras destaca-se o módulo de relatório que permite carregar novos modelos de relatórios com o sistema em produção e a sua exportação para o formato standard DICOM-SR, permitindo desta forma a sua integração com as imagens no repositório PACS. Em termos tecnológicos, desenvolveu-se uma aplicação web multiplataforma que segue uma arquitetura modular orientada a serviços e que oferece uma abstração relativamente à camada de persistência de dados.
The widespread adoption of digital medical images in various types of health institutions, has raised new problems regarding data and processes management. The standardisation of these scenarios has been subject of attention in the last decades, resulting in the development and promotion of standards such as DICOM and HL7. Currently, there are two kinds of information systems in medical imaging laboratories, that must operate in a collaborative manner, RIS which is responsible for managing the administrative tasks and PACS that manage images and associated information. This dissertation aimed to design and implement an RIS solution based on tools with no use restriction or open source. We begin by studying in detail the state of the art, including the open source and proprietary solutions, highlighting the strengths and weaknesses of each one. In addition to analysing the technologies used in the development of each solution, this study provided decisive contributions, regarding the project requirements. In particular, it allowed us to identify innovative features with high value to users. The achieved solution is an information system capable of managing all operations in a radiology department, including administrative management of patients, exam scheduling, conducting clinical reports, among others. Regarding innovative features, the reporting module stands out, since it allows to upload new report templates into the system and export these clinical reports in the DICOM-SR standard, thus allowing their integration with the images in a PACS repository. Regarding the technologies aspect, it was developed a multi-platform web application that follows a modular service-oriented architecture and also provides an abstraction in regard to the data persistence layer.

Full textBackground: Since Wilhelm Conrad Röntgen’s discovery of X-rays in 1896, radiology has undergone great changes. In Sweden, the process of digitalisation radiology was initiated in the mid 1990s. Aim: To describe the organisational changes that took place in five radiol- ogy clinics in Sweden in connection with the digitalisation of radiology. Study questions: How did the number and type of radiological examinations change when comparing two years before with two, four and six years after digitalisation? How did the number and distribution of hours worked change among different staff categories when comparing two years before with two, four and six years after digitalisation? How did the duties change after digitalisation within and between different staff categories at the radiology clinics? How do staff members in key positions describe the implementa- tion of digitalisation and any changes in their professional prac- tice after digitalisation? Method: Quantitative and qualitative methods were combined in order to answer the study questions. Five Swedish radiology clinics took part in the study, and production outcome data were gathered from each clinic. A total of 22 individuals were interviewed, with three to six interviews per radiology clinic. In order to gain an understanding of the positive results at one of the radiology clinics in terms of the increased number of exami- nations and reduction in the number of hours worked after digitalization a case study was conducted at this clinic, in which two questions were posed: How was the digitalisation carried out? How were workflow, im- plementation and changes followed up in detail after digitalisation? Ele- ments of Bramson and Bramson ́s (2005) perspectives and Kotter and Cohen’s (2002) success factors were applied. Findings: All radiology clinics had a small increase in the number of radio- logical examinations, while computed tomography and magnetic reso- nance imaging examinations increased significantly during the period un- der investigation. Thus, more complex examinations were carried out post digitalisation, a fact considered to have led to qualitatively better and safer diagnoses. The total working time was reduced at three clinics, while two exhibited an increase. The total number of hours worked increased for radiologists and radiographers but decreased for secretaries and assistant nurses. In general, radiologists and radiographers performed more tasks post digitalisation, and many of the traditional duties of secretaries and assistant nurses were eliminated or taken over by the computer. Digitalisa- tion enabled greater access to radiological images and patient data in addi- tion to improved quality and diagnostics of the radiological examination. Digitalisation also allowed a better-controlled workflow, as well as im- proving ergonomics, the environment and the coordination with other clinics. The case study interviews revealed themes describing: information, super users, education, clear work flows and routines, staff needs and motiva- tion as well as clear leadership throughout the change process. According to Bramson and Kotter, these themes are important for successful change. Conclusion: None of the individuals interviewed wished to return to the analogue mode of working. The digitalisation led to great changes for the different staff categories, with the advantages outweighing the disad- vantages. To succeed with change, Bramson’s perspectives and Kotter’s success factors should be taken into consideration.

Full textBackground: Profession as radiographer is constantly developing in Sweden valid skills development. There are many different ways in order to improve the profession internationally. One can, for example, take advanced practicing to become a reporting radiographer. The advanced practicing has exclusively showed positive results. Nowadays the patients are changing in conditions rapidly that the healthcare industry needs to adapt itself. Even the international development for radiographers seems bright, the need is yet fully realized in Sweden. Purpose: The purpose of this study is to find out which needs and possibilities are available for Swedish radiographers to improve and develop their own professional skills. Method: A qualitative interview study with semi-structured questions. The participants were selected by inclusions and exclusions. The interviews were conducted by telephone or physical meetings and the interviews were recorded and analyzed using qualitative content analysis manifest. Results: The responses from the participants have been varied. Lack of radiographers is palpable. All participants expressed that they had opportunities and possibilities for their radiographers to receive an advanced practicing in skills development even though the supply varied. The result shows that skills development is needed in all areas. Despite this, all hospitals do not express that skill development is important for their radiology department. Conclusion: Advanced skills development for radiographers is an interesting topic. There are more to figure out valid skill development. There is a need to develop radiographers in order to improve individually and together as X-ray department.
