Dual-energy x-ray absorptiometry in obesity.
48 CMAJ, January 7, 2014, 186(1) © 2014 Canadian Medical Association or its licensors Two patients with grade III obesity (body mass index [BMI] ≥ 40), a 31-year-old man (A) and a 26-year-old woman (B), underwent Roux-en-Y gastric bypass on vertical banded gastroplasty. Both patients followed the same nutritional and postsurgical approach. After 12 months, both patients achieved a similar reduc...
متن کاملComparison of Bone Mineral Density Measured by Dual X-ray, Axial Dual-energy Photon X-ray Absorptiometry and Laser Absorptiometry of Calcaneus
The objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual X-ray and laser (DXL) in a cross-sectional study carried out in an osteoporosis clinic. Measurements of bone mineral density (BMD) at proximal femur and spine were obtained by dual-energy photon X-ray absorptiometry (DEXA). Osteoporosis was defined by a DEXA T-score <-2.5 at the femora...
متن کاملEmerging trends in dual energy X-ray absorptiometry.
The risk of osteoporosis and cardiovascular disease increase significantly with age. Because of the long silent latency of these diseases, there is the opportunity for primary prevention before clinical symptoms occur. The newer fan beam dual energy x-ray absorptiometry (DXA) systems can detect vertebral fractures with fast, low dose lateral scans of the vertabrae from T4 to L4 in as little as ...
متن کاملDual-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...
