POS1110 RELIABILITY OF VERTEBRAL FRACTURE ASSESSMENT ON DUAL-ENERGY X-RAY ABSORPTIOMETRY

Vertebral fracture assessment : can dual - energy x - ray absorptiometry replace spine radiographs ?

Screening for vertebral fracture with dual x-ray absorptiometry.

Vertebral fractures are highly prevalent in the elderly population, and epidemiologic studies have found that these fractures are associated with an increased risk of future spine or hip fractures independent of bone mineral density. Only 20%-30% of vertebral fractures are recognized clinically; the rest are discovered incidentally on lateral spine radiographs. Lateral spine x-rays have not bee...

Ex Vivo and In Vivo Assessment of Vertebral Strength and Vertebral Fracture Risk Assessed by Dual Energy X-Ray Absorptiometry

Influence of vertebral fracture assessment by dual-energy X-ray absorptiometry on decision-making in osteoporosis: a structured vignette survey.

OBJECTIVE Vertebral fracture assessment (VFA) is a radiographic method using DXA to diagnose vertebral fractures, validated for reproducibility, sensitivity and specificity as compared with spine radiographs. This study was designed to assess the impact of VFA results on decision-marking in osteoporosis, using a clinical vignette-based approach. METHODS Twenty-nine rheumatologists provided da...

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...
