早产儿颅脑CT表现(附22例分析)

Cranial computed tomography features in normal premature infant(22 cases)

目的认识正常早产儿的颅脑的CT表现。方法复习22例早产儿临床资料及颅脑CT表现。结果早产儿脑实质密度较低,以两侧额叶及枕叶白质对称性低密度较为明显,胎龄越小,脑灰质厚度越薄:早产儿第三、第四脑室、两侧脑室、环池及侧裂池均可清楚显示,鞍上池、纵裂池仅部分显示,脑沟显示率最低。胎龄越小,脑室、脑池、脑裂形态显示越清楚。结论早产儿颅脑CT表现有一定的特点。

Objective Recognitoion cranial computed tomography features in nomal inpreature infant.Methods Review clinical datas and Cranial computed tomograpby features in inpremature infant 22 eases.Result brain substance density is lower in inpreature infhnt, especially symmetry in two side frontallobe and oeeipitalobe.Coneeptus age is more younger, the ectocinerea is more thicker;the third ventricle.fourth ventrical,lateral ventrieal, eistema ambiens and latera cleft all display clearly, suprasel lar cistern interhemispherie cistern display partly,anfractuosity display lowest.Conceptus age is more younger. , cerebral ventricle, cistern and schizencephaly display much clearly.Conclusion Cranial computed tomography features in normal inpremature infant has special features.
