摘　　要：目的评价采用三维超声自由解剖切面结合容积对比成像(VCI)技术观察胎儿小脑蚓部的效果,与VCI-C平面技术进行比较,获取胎儿各孕周小脑蚓部发育的正常参考值。方法对196胎正常胎儿,应用三维超声自由解剖切面结合VCI技术观察胎儿小脑蚓部,测量胎儿小脑蚓部上下径、前后径和面积,分析其与孕周的关系,并与Vials等的研究结果进行比较。结果三维超声自由解剖切面结合VCI方法的测量重复性好,所测得胎儿小脑蚓部测量值均与孕周呈正相关(P<0.01),与Vials等所得测量值相近。结论三维超声自由解剖切面结合VCI技术可准确测量胎儿小脑蚓部。Objective To evaluate fetal vermis with three-dimensional （3D） OmniView combining with volume contrast imaging （VCI）, and to obtain the normal value of vermis development throughout gestation compared with VCI-C plane. Methods A total of 196 normally developed fetuses were examined prospectively at 20--38 weeks＇gestation. 3D OmniView combining with VCI was used to observe fetal vermis. The fetal vermis was measured and analyzed with the gestational week, and compared with the results of Vifials＇. Results The repeatability of the measurements gained by OmniView combining with VCI was good. Measurements of the cerebellar vermis （AP diameter, CC diameter and surface area） correlated linearly with GA （P〈0.01）, and results were close to Viflals＇. Conclusion OmniView combining with VCI can be used to measure fetal vermis accurately.
