脑表面成像方法应用

目的　探讨脑表面成像技术在脑外科的应用。方法　对 2 4例在我院行头颅MRI扫描者加行脑表面成像扫描 ,其中 5例为健康查体 ,10例为胶质瘤 ,4例为转移瘤 ,3例为脑膜瘤 ,1例海绵状血管瘤 ,1例脑梗塞。结果　 5例正常扫描均能清楚地显示中央沟、外侧裂等大脑半球的主要沟回。 19例病变中 ,14例病变可以清楚地辨认出来 ,病灶与脑沟、脑回的位置关系十分清晰直观。 5例病变因周围水肿严重而显示欠佳。结论　脑表面成像技术可用于皮层及皮层下病变的定位及脑沟脑回异常的诊断 ,可部分代替神经导航的功能

The Application of Surface Anatomy Scanning

Objective To discuss the application of surface anatomy scanning in the department of cerebral surgery. Methods 24 cases were examined by surface anatomy scanning.These included 5 normal cases,10 gliomas,4 metastasis tumors,3 meningiomas,1 cavernous hemangioma and 1 cerebral infarction.Results 5 normal cases with surface anatomy scanning showed excellent visualization of the sulci and gyri on the surface of the brain.In 19 cases with cortical or subcortical lesions,14 cases showed the relationship between the lesion and the brain surface structures well.5 cases could not displayed because of server edema around the lesion.Conclusion The brain surface anatomy scanning is useful for the localization of cortical and subcortical pathology,for the diagnosis of the disease of sulci and gyri,can partly replace the navigation.
