Four patients with different disease entities (multiple cerebral metastases, cerebral infarct, cerebritis, and encephalitis) in whom x-ray computed tomography was either equivocal or negative showed apparent cerebral lesions by radionuclide studies. Equivocal CTs in the patients with multiple cerebral metastases or cerebral infarction may be attributed to the contraindication of contrast media and/or lack of cooperation during the examination procedure. In patients with cerebritis or encephalitis, radionuclide studies have proven to be more sensitive than CT early in the infectious disease process. In certain circumstances it is clinically beneficial and cost effective to evaluate the patient primarily by radionuclide scintigraphy.
4例患有不同疾病（多发性脑转移瘤、脑梗死、脑灰质炎和脑炎）的患者，其X线计算机断层扫描结果不明确或为阴性，但放射性核素检查显示有明显的脑部病变。多发性脑转移瘤或脑梗死患者的CT结果不明确可能归因于造影剂的禁忌和/或检查过程中患者不配合。对于脑灰质炎或脑炎患者，放射性核素检查已被证明在感染性疾病过程早期比CT更敏感。在某些情况下，主要通过放射性核素闪烁扫描对患者进行评估在临床上是有益的且具有成本效益。
