Fifty cases each of preterm (greater than 34 weeks), full term and one month to six months age (400 total) were subjected to cranial ultrasonography for determination of ventricular size and ventriculohemispheric ratio. Ventricular size steadily increased from 4.64 +/- 1.84 mm in preterm to 10.72 +/- 2.92 mm in six months old infant. Ventriculohemispheric ratio increased from 0.12 +/- 0.052 in preterm to 0.17 +/- 0.056 in three months of age. Then steady level was maintained at 0.17 +/- 0.064 upto six months of age.
分别对50例早产（大于34周）、足月及1个月至6个月龄的婴儿（共400例）进行头颅超声检查，以测定脑室大小和脑室与半球比值。脑室大小从早产儿的4.64±1.84毫米稳步增加到6个月龄婴儿的10.72±2.92毫米。脑室与半球比值从早产儿的0.12±0.052增加到3个月龄时的0.17±0.056。然后在6个月龄时维持在0.17±0.064的稳定水平。
