摘　　要：【目的】探讨超声背散射法在孕妇松质骨骨密度(BMD)测量中的应用价值。【方法】选取2017年6月至2018年7月在上海市长宁区妇幼保健院进行常规产检的235例孕妇,所有孕妇同时采用超声背散射法与超声透射法测量松质骨的BMD与超声传导速度(SOS),比较两种方法测量结果的差异;根据孕周不同将所有孕妇分为早孕组(<14周)、中孕组(14~28周)和晚孕组(>28周)三组,比较不同孕周孕妇超声背散射法测量的BMD与SOS。【结果】超声背散射法、超声透射法测量的孕妇BMD与SOS比较,差异无统计学意义(P>0.05)。早孕组超声背散射法所测BMD与SOS值明显高于中孕组与晚孕组(P<0.05),且中孕组明显高于晚孕组(P<0.05)。【结论】超声背散射法测量的BMD、SOS与超声透射法测量值比较,差异无统计学意义,可反映孕妇BMD随孕周的变化,可用于临床监测孕妇BMD。【Objective】To evaluate the feasibility of ultrasonic backscattering method in measuring cancellous bone mineral density parameters of pregnant women by comparing with ultrasonic transmission method.【Methods】A total of 235 cases of pregnant women were enrolled in this study from June 2017 to July 2018,who came to Shanghai Changing Maternity and Infant Health Hospital for routine examinations.All cases underwent measuring of bone mineral density(BMD)and speed of sound(SOS)by both ultrasonic backscattering method and ultrasonic transmission method.BMD and SOS were compared between the two method groups.All cases were divided into three study groups in terms pregnant phases:first trimester group(<14 gestational weeks),second trimester group(14~28 gestational weeks)and third trimester group(>28 gestational weeks).Both BMD and SOS obtained by ultrasonic backscattering method were compared among the three groups.【Results】There were no statistic differences of cancellous bone BMD and SOS obtained either by ultrasonic backscattering method or by ultrasonic transmission method(P>0.05).The cancellous bone BMD and SOS values measured by ultrasonic backscattering method of first trimester group were significantly higher than those of second and third trimester group(P<0.05),and the BMD and SOS values of second trimester group were significantly higher than those of third trimester group(P<0.05).【Conclusion】Cancellous bone BMD and SOS obtained by ultrasonic backscattering method showed no statistic differences from those detected by ultrasonic transmission method.Ultrasonic backscattering method can be used in bone mineral density monitoring in pregnant women,which reflect the changes in different gestational trimesters.
