新生儿颅脑正常CT表现

CT appearances of normal neonatal brain

目的 :观察新生儿颅脑正常CT表现 ,为新生儿颅脑疾病的诊断提供正常CT解剖依据。方法 :按样本纳入标准选择 60例新生儿进行颅脑CT扫描。结果 :发现新生儿颅脑具有脑白质密度较低 ,灰白质分界模糊 ,硬膜窦密度高 ,基底池和第四脑室宽大 ,存在透明隔间腔等特点。结论 :新生儿颅脑正常CT表现与成人明显不同。在新生儿颅脑疾病的CT诊断中 。

Objective:To provide more understanding of CT anatomic structures of normal neonatal brain by observing its CT appearances, which might warrant the diagnosis of some neonatal brain diseases.Methods:Sixty cases of the neonates satisfying the sampling criteria, underwent CT scanning of brain.Results:CT scans demonstrated the relative hypodensity of white matter,hazy margin between the grey and white matter,hyperdensity of dural sinus,relative wide basal cistern and the fourth ventricle,and the presence of interspace of septum pellucidum.Conclusion:CT appearance of the neonatal brain is obviously different from that of the adult.It is noteworthy that these normal CT findings should not be misdiagnosed as neonatal intracranial disease.
