[Bone ultrasound and diagnosis of osteoporosis: correlation of 2 quantitative ultrasound methods with bone density].

In this study, 96 women (mean +/- SD, 65.3 +/- 13.2 years) were investigated by bone mineral densitometry (DXA, Hologic QDR 2000) and quantitative ultrasound (QUS) of the tibia (n = 96; Sound-Scan2000, Myriad) and phalanges (n = 84: DBM Sonic 1200, IGEA). We observed a good correlation of QUS measurement with bone mineral content (BMD) on lumbar spine and both hips (Ward and Neck). Correlation of the two QUS-techniques measuring at different skeletal sites within the same patient was good. QUS instruments measuring at the various skeletal sites and their suitability for screening patients at risk of osteoporosis are discussed. The usefulness of the different QUS methods and the best measuring site for the assessment of fracture risk in osteoporotic patients still have to be established.
