中文摘要：
采用超声背散射法检测新生儿跟骨的超声背散射系数（Ultrasonic Backscatter Coefficient,BSC）,并分析BSC与出生胎龄、体重、身长和头围等因素之间的关系,从而评估BSC在评价新生儿松质骨状况中的作用。对122例新生儿的临床测试分析结果表明新生儿跟骨中的BSC与出生时的胎龄、体重和身长有良好的相关性。说明超声背散射信号及其BSC可用于评价新生儿的骨质量。
英文摘要：
Using ultrasonic backscattering method to detect backscattering signals in the calcaneus of neonates,and analyzing the relationships between backscattering coefficient（BSC） and gestational age,birthweight,length,head circumference and gender,the aim is to estimate the performance of BSC in bone status assessment of neonates.A total of 122 neonates participated in the study.The results show a significant correlation between the BSC and gestational age,birthweight and length at birth.This study suggests that the use of ultrasonic backscattering and the BSC is feasible for assessing the bone status of neonates.
