摘要: 新生儿骨发育状况的超声评价有重要意义。本文研究用超声背散射信号来评价新生儿骨发育状况的可行性。提出将超声表观积分背散射系数(AIB)用于评价新生儿松质骨状况,研究了不同超声频率下AIB与婴儿体重、出生天数之间的关系。研究结果表明,足月儿的AIB明显大于早产儿的AIB;足月儿的体重和AIB相关性较弱;早产儿的AIB参数和出生天数具有较高的正相关性(R=0.633)。说明超声背散射信号及其参数AIB可用于评价新生儿松质骨发育状况。

Abstract: Using ultrasound to evaluate the bone development of neonates is very important.The feasibility of evaluating the bone development was studied in this paper by using ultrasonic backscatter signal.Ultrasonic apparent integrated backscatter (AIB) coefficient was introduced to assess the cancellous bone status of the neonates.The correlations between AIB and weight, AIB and birth days of the neonates in different ultrasonic frequency were studied. The results showed that AIB of the term infants is apparently higher than that of premature infants and it has little correlation with the weight; while the AIB of the premature infants was highly correlated with the birth days (R = 0.633). Therefore,using ultrasonic backscatter signal and AIB coefficient has the potential to evaluate the cancellous bone developmentof the neonates.
