对63例接受化疗和放疗的恶性胶质瘤患者进行脑电图、99 mTc-DTPA脑显像和CT检查。评估肿瘤大小、中心透亮度、对比增强、周围水肿和脑室大小。CT表现被认为是可靠的，往往预测临床过程。临床恶化的患者肿瘤大小、中心透亮度和对比度增强增加，而临床改善的患者肿瘤大小、中心透亮度和对比度增强减少。CT扫描还提供了额外的信息价值的后续治疗，如囊肿或脑室梗阻的存在。一般来说，CT比其他诊断方法更能完整地显示肿瘤的特征。
Sixty-three patients with malignant glioma undergoing chemotherapy and radiotherapy were evaluated with electroencephalography, 99mTc-DTPA imaging, and computed tomography (CT). Tumor size, central lucency, contrast enhancement, surrounding edema, and ventricular size were assessed. CT findings were found to be reliable and often predicted the clinical course. Tumor size, central lucency, and contrast enhancement increased in patients with clinical deterioration and decreased in those with improvement. The CT scan also provided additional information of value in adjunctive therapy, such as the presence of cysts or ventricular obstruction. In general, CT gave a more complete profile of tumor characteristics than other diagnostic modalities.
