Growth of the fetal cerebellum was monitored by transverse cerebellar diameter (CD) from 14 to 39 weeks menstrual age in 125 Japanese fetuses. The growth curve for this parameter was determine using a Rossavik growth model [p = c(t)k & (t)]. An R2 value of 95.5% was obtained for CD. Variability analysis indicated a progressive increase in variability with fetal age for this parameter. Variability data were used with the growth curve model to determine a standard curve for this parameter. This standard curve provides a superior means to evaluate normal fetal cerebellar growth in the fetus and to identify cerebellar abnormalities in utero.
在125例日本胎儿中，通过测量孕14至39周时胎儿小脑横径（CD）来监测胎儿小脑的生长情况。使用Rossavik生长模型[p = c(t)k & (t)]确定该参数的生长曲线。CD的R2值为95.5%。变异分析表明，该参数的变异随胎龄增加而逐渐增大。将变异数据与生长曲线模型结合，确定该参数的标准曲线。这条标准曲线为评估胎儿正常小脑生长及识别子宫内小脑异常提供了更好的方法。
