本文总结了87例经手术或病理证实的脑照相结果。初步认为静态脑照相诊断颅内占位性病变的阳性率为83.9—89.7%。幕上病变为87.7%,幕下为64.3%。与其它检查方法比较,脑照相(扫描)是一安全、简便、阳性率较高的颅内病变诊断技术。初步分析了假阴性的漏诊原因及幕下病变阳性牢低的可能因素。对影响脑照相阳性率的病变本身因素及有关方法学问题作了简单的讨论。 This article summarizes 87 cases of pathologically confirmed brain imaging results. Preliminary believe that static brain imaging diagnosis of intracranial space-occupying lesions positive rate was 83.9-89.7%. Supratentorial disease was 87.7%, under the screen was 64.3%. Compared with other examination methods, brain photography (scanning) is a safe, simple, high positive rate of intracranial lesions diagnosis. Preliminary analysis of false negative causes of missed diagnosis and screen under the possibility of positive and low prison. On the factors that affect the positive rate of brain photographic positive factors and the methodological issues were briefly discussed.
