Dual-energy X-ray absorptiometry diagnostic discordance between Z-scores and T-scores in a young Iranian population
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 sampl...
متن کاملComparison of Singh index accuracy and dual energy X-ray absorptiometry bone mineral density measurement for evaluating osteoporosis
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...
متن کاملAssessment of bone mineral density with dual energy X-ray absorptiometry in pre- and post-menopausal women
Background: Osteoporosis is a chronic disease that contributes substantially to decrease physical activity and decline in the quality of life. Osteoporosis can be diagnosed easily with the use of dual-energy X-ray absorptiometry (DXA) equipment. The aim of this study was to investigate the magnitude of bone loss on proximal femur and lumbar spine LS in pre- and post-menopausal women f...
متن کاملediatric Dual - Energy X - ray Absorptiometry : echnique , Interpretation , and Clinical Applications arry
This article reviews the dual-energy x-ray absorptiometry (DXA) technique, its interpretation, and clinical applications with emphasis on the considerations unique to pediatrics. Specifically, the use of DXA in children requires the radiologist to be a “clinical pathologist,” monitoring the technical aspects of the DXA acquisition, a “statistician” knowledgeable in the concepts of Z-scores and ...
متن کاملA review of emerging trends in dual-energy X-ray absorptiometry (DXA)
New fan-beam DXA systems can detect vertebral fractures with fast, low-dose lateral scans of the vertebra from T4 to L4 in as little as 10 seconds. Vertebral fractures are the most common fracture in osteoporosis and an indication for treatment irrespective of Bone Mineral Density [1-3]. However, without a diagnostic test such as that available on fan-beam DXA systems, as many as 75% of vertebr...
