Quantitative ultrasound (QUS) on a specific region of interest (ROI) of the Os calcis: a new imaging technique

Broadband ultrasound attenuation was measured in 28 premenopausal women, 30 postmenopausal women, and 25 men using a new imaging device, the DTU-one. Short term in vivo precision was 1.2 CV%. The r-values for the correlation of BUA vs BMD at the hip, spine and lower forearm were 0.66, 0.64 and 0.62, respectively.
