Comparison 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...

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 کاملDual-energy x-ray absorptiometry: overused, neglected, or just misunderstood?
Assessment of bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) plays a vital role in the diagnosis of osteoporosis and in monitoring a patient's response to drug therapy. This commentary will discuss controversies surrounding the use of DXA for screening and monitoring of BMD in women.
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 ...
