摘　　要：目的探讨CT脑表面成像技术在临床上的应用。方法对16例CT平扫发现颅脑存在病变者加做脑表面CT重建,其中5例为脑出血,4例为硬膜外血肿,3例为脑血管畸形,2例为脑梗死,1例多发脑膜瘤,1例为胶质瘤。结果16例患者非病变区大脑的脑沟回均显示清楚。脑出血、肿瘤及梗塞患者病灶所在对应脑叶、脑沟肿胀,水肿也能清楚显示。脑血管畸形患者畸形血管区域显示脑组织不规则缺损区。硬膜外血肿患者可显示血肿大小和血肿与脑表面血管的关系以及血肿对脑表面压迹。结论CT脑表面成像技术可用于颅脑内血肿、肿瘤的手术定位及病变累及大脑表面的程度诊断,可部分取代MR的脑成像功能,适于基层应用。Objective To discuss the application of CT brain surface reconstruction canning. Methods The 16 cases,which included 5 cases of cerebral hemorrhage,4 cases of epidural hematoma,3 eases of cerebral vascular malformations,2 cases of cerebral infarction, 1 case of multiple meningioma. 1 case of glioma, revealed by CT scanning the existence of brain lesions were made to do the CT brain surface reconstruction scanning. Results 16 cases of patients with non-brain lesions of the brain areas,the sulei and gyri were showed clearly. Cerebral hemorrhage,tumor infarction and patients with brain lesions where the corresponding leaves,brain swelling,edema can be clearly demonstrated. Cerebral vascular malformations in patients with vascular malformations of regional brain tissue showed irregular defect. Hematoma size and the relationship between the hematoma and blood vessels can be seen and showed pressure traces on the brain surface..in patient with Epidural hematoma. Conclusion CT brain surface reconstruction scanning is useful for the localization of operation of intracmial hematoma and tumor and the extent diagnosis of the surface of the brain lesion.
