小儿侧脑室容量CT定量测定及临床应用研究

Quantitative study of lateral ventricle of children By CT

目的 研究正常小儿侧脑室容量CT定量测定从而确定正常小儿侧脑室容量参考值。方法 应用螺旋CT对172例正常小儿颅脑进行扫描,用部分容积分析法(PVA)对扫描图象进行侧脑室容量计算,并以20例病儿侧脑室容量作为对照,对所测得数据进行统计学分析得出小儿侧脑室容量的正常参考值。结果 正常活体小儿侧脑室容量正常参考值平均为10.93ml,95％正常值范围4.72-18.04ml。结论 3岁以后的正常小儿侧脑室容量与成人相似(P>0.05),婴幼儿侧脑室容量比学龄前期和学龄期小儿相对较大(P<0.01)。

Obyective The lateral ventricles of healthy children were studied by CT to make sure of the reference data of that of healthy children. Methods The heads of 172 healthy children were scanned with CT. The wlume of the lateral ventricles of these children was measured with the method ofpartical volamn analysis (PVA) ,and compared with the volume of the lateral ventrices of sick children. We used statistical methods for analysising all data collected from studying and got the reference data of the cateral ventricle of healthy children. Results The volume of lateral ventricle of the healthy children- averaged 10.93ml, ranging from4.72- 18.04 ml in 95% of the cases. Conclusion In older than 3 old years groups, the children' s healthy Lateral ventrie' s volume is Similar to the adult' s (p > 0.05),and the infant' s lateral ventricle' s volume is larger than preschool children' s and school children' s(p < 0.01).
