CONTEXT: Measurements of bone density taken by dual-energy x-ray absorptiometry are the most accurate procedure for the diagnosis of osteoporosis. This procedure has the disadvantage of measuring the density of all mineral components, including osteophytes, vascular and extra vertebral calcifications. These alterations can influence bone density results and densitometry interpretation. OBJECTIVE: To correlate radiography and densitometry findings from women with osteoporosis, analyzing the influence of degenerative processes and vertebral fractures on the evaluation of bone density. DESIGN: Retrospective study. SETTING: Osteoporosis outpatients' clinic at Hospital das Clínicas, Universidade Estadual de Campinas. PARTICIPANTS: Ninety-six postmenopausal women presenting osteoporosis diagnosed by bone density. MAIN MEASUREMENTS: Bone mineral density of the lumbar spine and femoral neck were measured by the technique of dual-energy x-ray absorptiometry, using a LUNAR-DPX densitometer. Fractures, osteophytes and aortic calcifications were evaluated by simple x-rays of the thoracic and lumbar spine. RESULTS: The x-rays confirmed vertebral fractures in 41.6%, osteophytes in 33.3% and calcifications of the aorta in 30.2%. The prevalence of fractures and aortic calcifications increased with age. The mean bone mineral density was 0.783g/cm² and the mean T-score was --3.47 DP. Neither fractures nor aortic calcifications had significant influence on bone mineral density (P = 0.36 and P = 0.09, respectively), despite the fractured vertebrae having greater bone mineral density (P < 0.02). Patients with lumbar spine osteophytes showed greater bone mineral density (P = 0.04). Osteophytosis was associated with lumbar spine bone mineral density after adjustment for fractures and aortic calcifications by multiple regression (P = 0.01). CONCLUSION: Osteophytes and lumbar spine fractures can overestimate bone density interpretation. The interpretation of densitometry results should be carried out together with the interpretation of a simple lumbar spine x-ray in elderly women.

Currently, the problem of reducing the risk of developing fat liver hepatosis from exposure to household and industrial toxicants among the working-age population continues to be an important medical and social problem, since not timely diagnosis of the disease can lead to its progressive course with the development of inflammatory changes, necrosis and liver fibrosis up to cirrhosis and hepatocellular cancer. In this regard, the search for methods and techniques that optimize the diagnosis of fat hepatosis is relevant. Modern methods of radiation diagnostics of liver density characteristics can significantly reduce subjectivity in the assessment of changes due to the use of quantitative indicators. The aim of study - improving the quality of x-ray diagnostics of fat liver disease based on a precision assessment of the density of the liver parenchyma using computed tomography. A comparative retrospective analysis of the results of a comprehensive clinical and radiological examination of 115 men of working age in the range of 40-55 years was performed. The main group (48 people) - employees of machine-building plants: shapers, stumpers, fitters-assemblers who had industrial contact with such factors as local vibration, dust, noise, muscle strain, burdened with a long alcoholic history and the presence of signs of metabolic syndrome: hyperlipidemia, impaired tolerance to carbohydrates, diabetes, abdominal obesity. The comparison group included representatives of auxiliary professions without clinical signs of pathology (47 people), comparable in age and experience with the main group. X-ray examinations were performed using computer tomographs: "HI Spead CT/e Dual" by GE Medical Systems and "Aqulion 64" by Toshiba. To measure the liver density in Hounsfield units (HU), the ROI (zone of interest) tool was used, which allows determining the desired value over areas of different dimensions. Measurements were performed on computer screens in 4 zones of interest at 4 levels of scanning of the liver lobes (apex, level of the caval gate, level of the left lobe, level of the portal gate) with the calculation of the average values of the density index (IDH) and density gradients (IDG) relative to the aorta, spleen and kidney. Analysis of the results of a posteriori CT densitometry of various parts of the liver within the framework of the developed algorithm, including the use of absolute and relative (gradient) x-ray density indicators of hepatic, vascular (aorta),splenic and renal structures, allowed us to expand our understanding of the quantitative density characteristics both in normal and in patients with signs of diffuse fat hepatosis (FH). It was found that the liver parenchyma density indicators can be a kind of (conditional), sometimes the only indicators of the degree of severity of changes that objectively manifest positive or negative dynamics of pathophysiological processes and, in particular, at the initial stages of the development of the studied pathology. Density differences in the right and left liver parenchyma in the control group (conditional norm) in terms of absolute density and its gradient, regardless of the level of scanning, were insignificant (statistically unreliable). In patients with clinical signs of fatty liver infiltration at the stage of steatosis, in the absence of x-ray morphologically detectable structural changes, a decrease in IDH and the dynamics of its increase (recovery) at various stages of observation were revealed. Even with comparatively equal IDH of the evaluated departments, the IDG of different people differed, manifesting the individuality of metabolic processes occurring in the body, in particular in the liver, is a kind of indicator of their direction and severity. The significance of density indicators as predictors of the subsequent stages of the pathology under consideration was particularly evident in the analysis of the results of primary diagnostics and its development in the dynamics of observations. The application of the developed methodological approach allowed us to expand our understanding of the possibilities of KT-liver densitometry in patients with metabolic syndrome (hyperlipidemia, impaired carbohydrate tolerance, diabetes mellitus, abdominal obesity) in the diagnosis of fatty liver disease (FLD) at various stages of examination, including in the early subclinical phases of pathology development. The results obtained indicate the predominant role of ethyl alcohol as a hepatotoxicant in the development of FLD in the estimated cohort of the working-age population. The use of an original algorithm for evaluating tissue density makes it possible to significantly ensure the objectivity of the interpretation of research results.

Streszczenie:

Technologies for the measurement of bone mineral density and other parameters of bone strength at peripheral skeletal sites have been studied since the 1960s. Single-energy Photon Absorptiometry (SPA), Radiographic Absorptiometry (RA), Radiogrametry (RG), Single-energy X-ray Absorptiometry (SXA), Peripheral Dual-energy X-ray Absorptiometry (pDXA), and Quantitative Ultrasonometry (QUS) have been successively evaluated. These technologies and their clinical applications are discussed in this article. The available scientific evidence supports the clinical use of these technologies at peripheral skeletal for assessment of fracture risk. Peripheral measurements other than the 33% (one-third) radius by DXA cannot be used to diagnose osteoporosis according to current standards. Peripheral skeletal sites are not clinically useful for monitoring changes in BMD with natural evolution of the disease and its treatment. Peripheral BMD measurement can theoretically be used to screen patients for selection to central DXA testing, although device-specific cut-points should be developed before this is implemented. When central DXA testing is not available, peripheral BMD testing may be considered to identify individuals who might benefit from pharmacological intervention.

Aim: To evaluate the clinical efficiency of computed tomography for diagnostics of patients with urolithiasis and the choice of treatment strategy. Material and methods: The study was carried out at the Urological Clinic of I.M. Sechenov First Moscow State Medical University and included 1044 patients with urinary stones. The ultimate goal of this study was to predict the clinical efficiency of extracorporeal shock wave lithotripsy using a combination of computed tomography and densitometry. Extracorporeal shock wave lithotripsy was performed on “Siemens Lithostar Plus,” “Siemens Modularis Uro,” and “Dornier Gemini” lithotripters. Statistical analysis of clinical data included evaluation of individual sampling groups and calculation of weighted arithmetic mean ( M). Results: The efficiency of extracorporeal shock wave lithotripsy has been determined primarily using X-ray analysis of the concrement outlines and the structure (homogeneous or heterogeneous) of its central zone. However, in terms of efficiency and repetition rate (the number of fragmentation procedures required for complete clearance) of extracorporeal shock wave lithotripsy, the mean density of the concrement along the whole length of its three-dimensional structure (expressed in Hounsfield units) appeared to be the most reliable and informative predictive index in this study. Conclusion: The combination of computed tomography with densitometry in the treatment of patients with urolithiasis allows one (1) to determine the exact localization, size, X-ray structure, and structural density of urinary stones and (2) to predict, on the basis of densitometric data histograms, the clinical efficiency and repetition rate of extracorporeal shock wave lithotripsy with due regard to the X-ray structure of peripheral and central zones, and mean density (in Hounsfield units) of urinary concrements.

[Truncated abstract] Areal bone mineral density (BMD) is measured routinely in the clinic by a quantitative radiological technique, dual-energy X-ray absorptiometry (DXA). BMD is used widely to assess non-invasively but indirectly the mechanical fragility of bone and consequently is able to predict fracture risk. While BMD correlates well with in vitro measurements of bone strength it does not directly measure a mechanical property; half of incident minimally traumatic fractures in women occur with BMD values above the World Health Organisation defined threshold for osteoporosis. This arises partly because the mechanical strength of bone is dependent on its structural geometry and material strength as well as bone mineral mass. Essentially, bones fracture when load stresses exceed the mechanical capacity of the material to withstand them. The structural geometry (i.e., the amount of bone tissue and its complex three-dimensional arrangement within the macroscopic bone envelope) defines the stresses produced by a given load, while the intrinsic load capacity of the material is defined by the composition and microstructure of the bone tissue itself. Hip structural analysis (HSA) is a technique that elucidates the structural geometric component of bone strength; essentially combining information available from conventional DXA images of the proximal femur with a biomechanical beam model based on the stresses arising in a combination of pure bending and axial compression. A version of HSA has recently been released commercially, and has obtained US Food and Drug Administration approval for its clinical application. ... Given the acknowledged limitations of the HSA method when applied to 2-D projection images, a 3-D approach to structural geometry, using imaging modalities such as pQCT and QCT or a recently introduced version of DXA that mimics QCT, is indicated for the future. With that in mind and the possibility of the anthropometric phantom being adopted for future accuracy and precision assessments, improvements in the design of this phantom are recommended. Studies to better understand and verify Contents v the relevance of the 'local buckling' phenomenon as a structural geometric factor in the genesis of macro-fractures are also recommended. In summary, it is essential that superior (compared to BMD) non-invasively determined clinical predictors of bone fragility leading to fracture be investigated. Structural geometric variables are potential candidates. This has led to consideration of; (i) the need to progress beyond BMD for a more sensitive and specific bone strength measurement; (ii) theoretical advantages of structural geometry over BMD; (iii) limitations of the current HSA technique based on DXA, including those introduced by its restrictive assumptions; (iv) the value of HSA in longitudinal studies, exemplified by the 'normal' but rapid skeletal changes seen in human lactation, with possible implications for an analogous study of the menopause; and (v) an investigation, using a custom-designed anthropometric phantom, of the adaptation of HSA to certain emerging imaging modalities and methods able to resolve bone structural geometry in three dimensions.

International Society for Clinical Densitometry (ISCD) rekommenderar att precisionsbestämning av bentäthetsmätning görs på varje klinik för att bedöma reproducerbarheten. Bentäthetsmätning görs för att diagnosticera osteoporos, följa upp behandling och förutsäga frakturrisk. I studien användes Dual energy x-ray absorptiometry (DXA) för att utföra dubbla mätningar på redan inbokade patienter på klinisk fysiologi, Skånes Universitetssjukhus (SUS), Lund. 105 patienter ingick i studien. Mätningarna utfördes på helkropp, totalhöft, lårbenshals och ländrygg. Helkroppsmätningar ingick i en interindividuell studie och de övriga ingick i intraindividuella studier. Reproducerbarheten uttrycktes som minsta signifikanta skillnaden (LSC), root mean square standardavvikelse (RMS SD) och variationskoefficient (%CV). Reproducerbarheten i studien var god med låga värden för LSC och RMS SD. %CV understeg de av ISCD rekommenderade maxvärdena, vilka är 1,8 % för totalhöft, 2,5 % för lårbenshals och 1,9 % för ländrygg.
It is recommended by the International Society for Clinical Densitometry (ISCD) that every clinic performs a precision assessment of bone densitometry to evaluate the reproducibility. Bone densitometry is used for diagnosis of osteoporosis, to monitor response to treatment and to assess patients’ risk of fractures. Dual energy x-ray absorptiometry (DXA) was used to perform double scans of patients already booked for examination at the section of clinical physiology, Skåne University Hospital (SUS), Lund. 105 patients were included in the study. Measurements were made at whole body, total hip, femoral neck and lumbar spine. The whole body scans were included in an interindividual study, whereas the others were included in intraindividual studies. The reproducibility was expressed as least significant change (LSC), root mean square standard deviation (RMS SD) and coefficient of variation (%CV). The reproducibility in the study was good, with low values for LSC and RMS SD. %CV fell below the maximal values recommended by the ISCD, which are 1,8 % for total hip, 2,5 % for femoral neck and 1,9 % for lumbar spine.

Resumo: A densitometria radiográfica é técnica que permite avaliar a densidade óssea, utilizando referências confeccionadas em material inerte (ex. alumínio), principalmente para investigação de alterações ósseas e doenças como a osteoporose. Para aumentar a precisão de técnica, alguns autores propõe o uso de equações matemáticas, como métodos dos mínimos quadrados, teorema de LaPlace e regra de Sarrus o que permitirá obter melhor ajuste da curva característica de absorção aos raios-X pelo objeto de estudo. O uso de tecnologias como Java, gnuplot, broffice calc, todas elas de código aberto, possibilitou-nos o desenvolvimento do software "ODR-ATA", capaz de analisar e processar imagens radiográficas digitais ou digitalizadas e calcular valores de densidade próximos aos valores do objeto em estudo. Atualmente diversas soluções pagas possuem suporte para realizar a densitometria radiográfica. O objetivo deste estudo foi desenvolver uma solução computacional de código livre, para cálculo da densidade óssea a partir da densitometria radiográfica. Para testar o software, foi realizado um experimento a partir de uma tomada radiográfica de uma escada de alumínio de valores conhecidos. Foram feitas 10 repetições e avaliados os degraus 4, 5, 6, 7 e 8 da escada de alumínio. Os resultados obtidos pelo "ODR-ATA" para os degraus 5, 6, 7 e 8 demonstraram uma precisão e exatidão de ordem de 3,64% e 3,63% respectivamente, atestando a validade e confiabilidadena utilização do software na obtenção da densidade óssea obtida pela densidade radiográfica.
Abstract: The radiographic densitometry is the technic that allows the evaluation of bone density, which uses references created in inert material (e.g. aluminium) especially to the investigation of bone modifications and illnesses such as osteoporosis. To increase technical precision some authors suggest the use of mathematical equations, such as the least squares method, Laplace's theorem, and the Rule of Sarrus allowing better results when achieving the adjustment of the curve that is characteristic of X-ray absorption by what is being studied. The usage of technologies such as Java, gnuplot, broffice calc, all of open code, allowed us to develop the software "ODR-ATA", which is capable of analyzing and processing digital radiographic images and of calculating values of density close to the values of the object under study. Recently, various paid solutions have the support to perform radiographic densitometry. The purpose of this study is to develop a computational solution of free code to calculate bone density starting from the radiographic densitometry. In order to test the software I performed an experiment that started with the radiography of an aluminum ladder of unknown values. I performed 10 repetitions and evaluated steps 4,5,6,7, and 8 of the aluminum ladder. The results I achieved with "ODR-ATA" for steps of number 5,6,7, and 8 show a precision of 3,64%% and 3,63% respectively, which attest for the validity and reliability of the software in the discovery of the bone density obtained through the radiographic densitometry
