The objective of this study was to assess the value of ultrasonic backscatter signals and the backscatter coefficient (BSC) in the analysis of bone status in neonates and to analyze the relationships between the BSC and gestational age, birth weight, length, head circumference and gender. A total of 122 neonates participated in the study, including 83 premature infants and 39 full-term infants. Their BSCs were measured by ultrasound after birth. The results revealed a significant correlation between the BSC and gestational age (R = 0.47, p < 0.001), birth weight (R = 0.47, p < 0.0001) and length at birth (R = 0.43, p < 0.001) at a frequency of 5.0 MHz. This study suggests that the use of ultrasonic backscattering and the BSC is feasible for assessment of the bone status of neonates.
本研究旨在评估超声背向散射信号及背向散射系数（BSC）在分析新生儿骨骼状况方面的价值，并分析 BSC 与胎龄、出生体重、身长、头围和性别之间的关系。共纳入 122 例新生儿，包括 83 例早产儿和 39 例足月儿。他们在出生后通过超声测量 BSC。结果显示，在 5.0MHz 频率下，BSC 与胎龄（R=0.47，p＜0.001）、出生体重（R=0.47，p＜0.0001）和出生时身长（R=0.43，p＜0.001）呈显著相关。本研究表明，超声背向散射和 BSC 可用于评估新生儿骨骼状况。
