Screening for vertebral fracture with dual x-ray absorptiometry.

Comparison between the gold standard DXA with calcaneal quantitative ultrasound based-strategy (QUS) to detect osteoporosis in an HIV infected cohort.

INTRODUCTION Osteoporosis represents one of the most frequent comorbidity among HIV patients. The current standard method for osteoporosis diagnosis is dual-energy X-ray absorptiometry. Calcaneal quantitative ultrasound can provide information about bone quality. The aims of this study are to compare these two methods and to evaluate their ability to screen for vertebral fracture. METHODS Thi...

Clinical evaluation of spine morphometric X-ray absorptiometry.

A new method for vertebral height measurements, morphometric X-ray absorptiometry (MXA) based on dual-energy X-ray absorptiometry, has been proposed. This technique overcomes some limitations of morphometric radiography (MRX): the effective radiation dose is low, some sources of geometric distortion are eliminated, such as dependence on patient position, magnification gradient, and the effect o...

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

Osteoporosis Diagnosis and Screening

9 Osteoporosis and osteoporotic fracture are major causes of morbidity and mortality in the United States and worldwide. Nearly half of all women and one quarter of men >50 years of age will experience an osteoporosisrelated fracture during their lifetime. The diagnosis of osteoporosis in postmenopausal women and older men can be made definitively by comparing bone mineral density (BMD) measure...

A 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...
