fracture. several chronic medical conditions, medications, and life style factors affect bone mineral accrual. this study aims to evaluate the bone mineral densities and hip axis lengths in the local population. materials and methods: 336 normal bangladeshi women age ranges 20 to 70 years had evaluation of their bone mineral densities (bmds) by means of dual x-ray absorptiometry (dxa). results:...

We propose a method for estimating the bone mineral density (BMD) from plain x-ray image. Dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT) provide high accuracy in diagnosing osteoporosis; however, these modalities require special equipment scan protocols. Measuring BMD an image provides opportunistic screening, which is potentially useful early diagnosis. The p...

Abstract Background and Aims Mineral bone disease (BMD) is one of the common complications advanced chronic kidney (CKD). Fracture risk could be predicted by densitometry using dual-energy X-ray absorptiometry (DXA) quantitative computed tomography (QCT). This study aims to evaluate effectiveness imaging techniques in diagnosing BMD CKD patients healthy subjects. Method We performed control cro...

Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...

BACKGROUND The aims were to explore bone mineral density (BMD) by digital X-ray radiogrammetry (DXR) in postmenopausal women with long-lasting rheumatoid arthritis (RA) in relation to dual x-ray absorptiometry (DXA)-BMD, joint destruction by conventional radiographs and disease related variables in a cross-sectional study. METHODS Seventy-five postmenopausal women with RA were examined by DXA...

OBJECTIVE Reduced bone mineral density (BMD), assessed by Dual Energy X-ray absorptiometry (DXA), is a well-known risk factor for fragility fracture. A large proportion of patients with fracture have only slightly reduced BMD. Assessment of other bone structure features than BMD may improve identification of individuals at increased fracture risk. Digital X-ray radiogrammetry (DXR), which is a ...

background: dual-energy x-ray absorptiometry (dxa) is considered the gold standard for non-invasive measurement of bone mass. t-scores and z-scores are used to present the results of bone mass. the present study was designed to evaluate the discordance between t-scores and z-scores calculated at a same level and its relation with age, gender and body mass index (bmi) in a representative sample ...

An accurate, rapid, and convenient method is presented for moisture content (MC) 10 determination of solid wood based on dual-energy X-ray absorptiometry (DXA). Poly(methyl methacrylate)-equivalent thicknesses (PMMA-EThs) of sugi (Cryptomeria japonica D. Don) wood blocks and pure water were measured by means of a wide range of X-ray tube voltages (20–100 kV). The ratio of the PMMA-ETh of pure w...

CONTEXT Due to maldigestion, pancreatic exocrine insufficiency (PEI) in chronic pancreatitis may lead to deficiencies in fat-soluble vitamins, including vitamin D. This may, in turn, can cause disturbances in bone metabolism and reduce bone mineral density. OBJECTIVE To conduct a prospective study of maldigestion, bone metabolism, and bone mineral density in a group of patients with chronic p...
