作者对46例脑肿瘤患者进行前瞻性研究,肿瘤切除术后行CT扫描。所有病例于术前行CT平扫和CT增强检查。男25例,女21例,年龄19～76岁(平均48岁)。42例为幕上肿瘤,4例幕下肿瘤。术前将病人分为三组:A组(24例)为不均匀强化(恶性胶质瘤,恶性星形细胞瘤,颅内转移瘤),B组(14例)为均匀强化(各种良性肿瘤),C组(8例)为未强化(低分化神经胶质瘤)。为减轻肿瘤周围脑水肿,术前和术后的39例患者均应用类固醇治疗。所有术后CT扫描均于手术当日完成,自手术结束到CT
The authors conducted a prospective study of 46 patients with brain tumors, CT scan after tumor resection. All cases underwent CT scan and CT enhancement before operation. 25 males and 21 females, aged 19 to 76 years (mean 48 years). 42 cases of supratentorial tumors, 4 cases of infratentorial tumors. Patients were divided into three groups preoperatively: group A (24 cases) with heterogeneous enhancement (glioblastoma, malignant astrocytoma, intracranial metastases), group B (14 cases) with uniform enhancement Tumor), group C (n = 8) was not enhanced (poorly differentiated glioma). To reduce brain edema around the tumor, 39 patients were treated with steroids preoperatively and postoperatively. All postoperative CT scans were performed on the day of surgery, from the end of surgery to CT
