The preoperative contrast enhanced CT and radionuclide brain scans of 60 patients with surgically verified supratentorial astrocytomas were evaluated and compared. Results indicated that the mechanisms of contrast enhancement and radionuclide uptake are identical in the detection of supratentorial gliomas. These diagnostic methods apparently mirror the integrity of the blood-brain barrier and therefore can be useful in assessing the degree of malignancy of supratentorial gliomas. However, lesions with an intact blood-brain barrier will be missed with radionuclide imaging. These parenchymal abnormalities and/or the associated mass effect will be detected with contrast enhanced computed tomography. These findings firmly establish contrast enhanced computed tomography. These findings firmly establish contrast enhanced CT as the primary investigate tool in the suspected brain tumor.
对60例经手术证实的幕上星形细胞瘤患者的术前增强CT和放射性核素脑扫描进行了评估和比较。结果表明，在幕上胶质瘤的检测中，增强CT和放射性核素摄取的机制是相同的。这些诊断方法显然反映了血脑屏障的完整性，因此可用于评估幕上胶质瘤的恶性程度。然而，放射性核素成像会漏诊血脑屏障完整的病变。这些实质异常和/或相关的占位效应可通过增强CT检测到。这些发现明确了增强CT的地位。这些发现明确了增强CT作为疑似脑肿瘤主要检查工具的地位。
