The usefulness of brain scanning in the diagnosis and management of strokes was evaluated in 313 serial cases. Of 38 patients with transient ischemic attacks (TIAs), only one had a positive test. The optimal time for scanning completed strokes was between seven and 14 days after onset. The pattern of uptake was characteristic of a vascular lesion in 76.8%. When uptake was indistinguishable from tumor, follow-up scans were useful. Patients with negative scans in the second week have a significantly better prognosis than the ones with a positive study. Cerebral angiography and brain scan correlated well in 56 patients who had both tests performed. The postmortem findings in 12 cases again emphasize the importance of the correct timing of the study, and the fact that a brain scan does not usually demonstrate lesions smaller than 2 cm in diameter. It is concluded that the brain scan represents a useful tool in the diagnosis of strokes and helps in predicting the degree of recovery following a vascular insult.
对313例连续病例评估了脑部扫描在中风诊断和治疗中的作用。在38例短暂性脑缺血发作（TIA）患者中，只有1例检查呈阳性。扫描完全性中风的最佳时间是发病后7至14天。76.8%的摄取模式具有血管病变的特征。当摄取情况与肿瘤难以区分时，随访扫描很有用。第二周扫描阴性的患者预后明显好于扫描阳性的患者。56例同时进行了脑血管造影和脑部扫描的患者，两者结果相关性良好。12例尸检结果再次强调了研究正确时机的重要性，以及脑部扫描通常无法显示直径小于2厘米病变的事实。结论是，脑部扫描是中风诊断的有用工具，有助于预测血管损伤后的恢复程度。
