Quantitative ultrasound measurement and evaluation of bone quality in normal Hubei Yichang subjects / 中国医师进修杂志

ABSTRACT

Objective To measure the parameters of ealeaneal quantitative ultrasound(QUS)in nomal Hubei Yichang subjects.which were compared between different age groups after standardization by body mass index(BMI).Methods Calcaneal parameters were measured by UBIS5000 in 2912 normal Hubei Yichang subjects,from 20 to 82 years old women 1450,men 1462).Results The peak values of broadband ultrasound attenuation(BUA)and stiffness(STI)of the calcaneal were both in 45-49 year group for women.The peak value of BUA was in 50-54 year group for men.Standardized by BMI,the peak value of BUA、STI and sound of speed(SOS)were both in 20-24 year groups for women and men.Conclusion BUA、SOS and STI of the calcaneal may change with age.After the influence of body mass is eliminated,the change still exists obviously,and the parameters may gradually reduce with increasing age.
