摘　　要：目的通过对57例妊娠分别使用二维、三维超声测量相关参数估计胎重,并作统计学比较,从而评价三维超声对于估测胎儿体重、诊断胎儿发育迟缓及巨大胎的优势和价值。方法对2005年10月至2006年3月间在我院分娩的57例妊娠,研究组用三维超声测胎儿股容积估计胎重,对照组用二维超声同步测量相关参数估计胎重。结果对两组估重结果与胎儿实际出生体重作相关统计学分析,研究组相关系数为0.983,对照组为0.906(P<0.05),前者与实际体重关系更密切。结论三维超声测量胎儿股容积估测胎儿体重,较传统二维超声具有更大优势,对于发现胎儿发育迟缓(FGR)及巨大胎意义重大,有利于指导临床治疗、选择分娩方式。Objective： We measured related parameters of 57 fetuses to predict fetal weight by two -dimentional ultrasonography and three -dimentional ultrasonography, compared the statistical results of two groups, then evaluate the value and the advantages of three -dimentional ultrasonography for predicting fetal weight and diagnosing fetal growth restriction and macrosomia. Methods： We examined 57 cases born in our hospital from November 2005 to March 2006. We measured fetal thigh volume by three - dimentional ul- trasonography in study group, then measured other fetal parameters by two -dimentional ultrasonography in control group. The weight can be calculated by corresponding formulation. Results： We use correlation analysis and calculated the statistical parameters. The correlation coefficient of study group is bigger than control group （ P〈0.05）, we think the weight of study group is nearer to actual weight. Conclusion： To compare with two - dimentional ultrasonography, predicting fetal weight by measuring fetal thigh Volume has more advantages, it＇s important to find fetal growth restriction and macrosomia. It＇s also useful to guide clinical treatment.
