Delayed necrosis of the brain following exposure to high doses of radiation is a recognized hazard. It is important to predict the nature of these postradiation changes, since surgical removal of radiation necrosis may reverse neurological deterioration of patients so affected. The present report stresses the importance of correlating the findings on computed tomography (CT) scans and zones of high radiation dose on dose reconstruction plans in order to differentiate between delayed radiation necrosis and tumors of the brain. This differentiation is not possible using the criteria of CT alone.
高剂量辐射照射后发生的迟发性脑坏死是一种公认的危害。预测这些辐射后变化的性质很重要，因为手术切除放射性坏死可能会逆转受影响患者的神经功能恶化。本报告强调了将计算机断层扫描（CT）扫描结果与剂量重建计划中的高辐射剂量区域相关联的重要性，以便区分迟发性放射性坏死和脑肿瘤。仅使用CT标准无法进行这种区分。
