Use of routine thoracic and abdominal computed tomography scans for assessing bone mineral density and detecting osteoporosis.

Objective: Evaluation of computed tomography (CT) attenuation measurements for assessing bone mineral density (BMD) and predicting osteoporosis in thoracic and abdominal CT scans for various clinical indications using dual-energy X-ray absorptiometry (DXA) as reference standard.

Research Design And Methods: A total of 234 patients (147 women, 87 men) undergoing DXA and CT were examined retrospectively. Mean time between both studies was 0.
