Measured fetal transverse cerebellar diameters were obtained by ultrasonography in 325 women during 20-42 weeks of gestation. A nomogram for transverse cerebellar diameter with respect to gestational age was generated. Curvilinear relationship was found between the transverse cerebellar diameter and the gestational age (R = 0.99624, P less than 0.0005). Fetal transverse cerebellar diameter, biparietal diameter, head circumference, abdominal diameter, abdominal circumference and femur length were measured by ultrasound in 39 women not more than one week before delivery. Correlation coefficients between the birth weights and these parameters were studied. It was found that the correlation between the transverse cerebellar diameter and the birth weight was the highest. The function of the transverse cerebellar diameter in the evaluation of fetal growth and development is better than any other parameter. The transverse cerebellar diameters of 20 IUGR cases were obtained. It was indicated that the growth of the transverse cerebellar diameter slowed down in primary symmetric IUGR, and was unaffected in secondary asymmetric IUGR. Thus it has clinical diagnostic value in symmetric IUGR. When combined with the abdominal circumference, the fetal cerebellar transverse diameter may help to differentiate the types of growth-retarded fetuses.
在325名妊娠20 - 42周的女性中，通过超声检查测量胎儿小脑横径。绘制了小脑横径与孕周的列线图。发现小脑横径与孕周之间存在曲线关系（R = 0.99624，P < 0.0005）。在39名分娩前不超过一周的女性中，通过超声测量胎儿小脑横径、双顶径、头围、腹径、腹围和股骨长度。研究了出生体重与这些参数之间的相关系数。发现小脑横径与出生体重之间的相关性最高。小脑横径在评估胎儿生长发育方面的作用优于任何其他参数。获得了20例宫内生长受限（IUGR）病例的小脑横径。结果表明，原发性对称性IUGR中小脑横径生长减慢，继发性非对称性IUGR中则不受影响。因此，它在对称性IUGR中有临床诊断价值。当与腹围相结合时，胎儿小脑横径可能有助于区分生长受限胎儿的类型。
