方法测量200例孕20 ~ 40周正常胎儿心外膜舒张末期基底-心尖长度（BAL）和横径（TL），计算GSI（BAL/TL）。前瞻性检查了300只妊娠17 - 39周的研究胎仔。计算每个胎儿的GSI，Z评分和百分位数。结果对照组胎儿的GSI（1.233; SD，0.0953）与胎龄无关。18%的研究胎儿（300个中的55个）GSI低于第5百分位数（
ObjectivesThe purpose of this study was to evaluate the global sphericity index (GSI) of the 4-chamber view and correlate the results with abnormal ultrasound findings.MethodsThe epicardial end-diastolic basal-apical length (BAL) and transverse length (TL) of the 4-chamber view were measured to compute the GSI (BAL/TL) in 200 control fetuses between 20 and 40 weeks' gestation. Three hundred study fetuses were prospectively examined between 17 and 39 weeks' gestation. The GSI, Z score, and centile were computed for each of the fetuses.ResultsThe GSI (1.233; SD, 0.0953) in the control fetuses was independent of gestational age. Eighteen percent of the study fetuses (55 of 300) had a GSI below the 5th centile (
