ABSTRACT
Objectives : Quantitative ultrasound of the calcaneus is an alternative to dual-energy X-ray absorptiometry for measurement of bone mass. Various studies have demonstrated correlation between broadband ultrasound attenuation and bone mineral density in Caucasian populations. This study compares the use of broadband ultrasound attenuation (BUA) measurements with bone mineral density (BMD) for osteoporosis screening in the Asian population. Design: A comparative study comparing calcaneal broadband ultrasound attenuation measurements and hip bone mineral density. Materials and Methods: 32 subjects with osteoporotic hip and vertebral fractures underwent calcaneal broadband ultrasound attenuation and dual-energy X-ray absorptiometry. The results of both tests are compared. Results: There is moderate correlation with Pearson’s correlation coefficient, r = 0.688 (p
