摘 要：Introduction:There is much diversity in the development of QUS *** of them use transducers that are fixed with respect to the *** there is the possibility that,depending on foot size,the location of the calcaneus interrogated will vary.A pilot study was set up to quantify the variation in BMD between manufacturer-fixed(relative to footplate) region of interest(ROI) and a constant,anatomical ROI(defined as 15%of foot length). Methods:26 young male(n=12) and female(n=14) normals aged 22 to 54 years(35.6+/-10) with foot length of 21.5 to 29.7 cm (25.1 cm +/- 2.3) were *** recently FDA-approved QUS devices,the Sahara(Hologic) and Achilles+(Lunar),were used in this *** position of the transducers on the subject was
