Over a 3-year period, 667 brain scans were performed, of which the results in 632 have been analysed. Positive scans were found in 68% of 204 cerebral tumours. There was a high rate of detection of meningiomas and malignant gliomas. Scanning was less helpful in visualizing slowly growing gliomas, and those tumours situated in the mid-line or posterior fossa. Metastases occupied an intermediate position. Positive scans occurred in a proportion of patients following acute cerebro-vascular accidents, and in a few other miscellaneous disorders. Virtually all patients with transient cerebral ischaemia, migraine, epilepsy and presenile dementia had normal brain scans. The value and limitations of this investigation have been discussed.
在3年期间，共进行了667次脑部扫描，其中对632次扫描结果进行了分析。在204例脑肿瘤患者中，68%的扫描结果呈阳性。脑膜瘤和恶性胶质瘤的检出率较高。扫描对于观察生长缓慢的胶质瘤以及位于中线或后颅窝的肿瘤帮助较小。转移瘤的情况处于中间位置。部分急性脑血管意外患者以及其他一些杂症患者的扫描结果呈阳性。几乎所有短暂性脑缺血、偏头痛、癫痫和早老性痴呆患者的脑部扫描结果均正常。本文已对该项检查的价值和局限性进行了讨论。
