Clinical applications of body composition measurements using DXA.
Dual-energy X-ray absorptiometry (DXA) scanning was primarily developed for the diagnosis of osteoporosis and was initially applied to studies of the clinically important sites of the lumbar spine, femoral neck, and forearm. The rapid adoption of DXA has led to the development of different, competing generations of equipment. Improvements have been achieved through advances in X-ray generation ...
متن کاملWhole Body Composition by Hologic QDR 4500/A DXA: System Reliability versus User Accuracy and Precision
Accurate and precise measurement of human tissue composition is both important and imperative in individual health assessment. Although body composition (BC) data acquisition and analysis are both popular and important, selecting an appropriate method or technique for accurate and/or precise assessment of individuals and/or groups remains a challenging task within various sectors of public heal...

متن کاملEvaluation of a new body composition phantom for quality control and cross-calibration of DXA devices.
This study evaluated a new body composition phantom and its use for quality control and cross-calibration of dual-energy X-ray absorptiometry (DXA) instruments for measurements of body composition. We imaged the variable composition phantom (Lunar, Madison, WI) on eight different DXA devices. Deviations of up to 7% fat were observed when we compared the percent fat values measured by the differ...
متن کاملAssessing body composition with DXA and bioimpedance: effects of obesity, physical activity, and age.
OBJECTIVE This study evaluated to what extent dual-energy X-ray absorptiometry (DXA) and two types of bioimpedance analysis (BIA) yield similar results for body fat mass (FM) in men and women with different levels of obesity and physical activity (PA). METHODS AND PROCEDURES The study population consisted of 37-81-year-old Finnish people (82 men and 86 women). FM% was estimated using DXA (GE ...
