Computed tomography (CT) has been reported to show normal findings in 13-52% of patients with cerebrovascular diseases. Among factors deciding the diagnostic accuracy are the size and location of the lesion, the time elapsed from onset to examination, the use of contrast enhancement and the type of CT scanner used. To further elucidate these aspects, we designed the present study including 300 consecutive patients, all investigated by CT with a 160 x 160 matrix and cerebrospinal fluid spectrophotometry (CSF-SPE). CT indicated a specific diagnosis in 52.7%. In the majority of the remaining cases, additional subclassification was possible by CSF-SPE, emphasizing the complementary information obtained by combined examinations. CT was also found to be a useful tool for reliable prognostic prediction, irrespective of the initial clinical course.
据报道，在患有脑血管疾病的患者中，13%至52%的患者计算机断层扫描（CT）结果正常。决定诊断准确性的因素包括病变的大小和位置、发病至检查的时间、是否使用对比增强以及所使用的CT扫描仪类型。为了进一步阐明这些方面，我们设计了本研究，纳入了300例连续患者，所有患者均接受了160×160矩阵的CT检查和脑脊液分光光度法（CSF-SPE）检查。CT明确诊断率为52.7%。在大多数其余病例中，通过CSF-SPE可以进行进一步的亚分类，这强调了联合检查所获得的补充信息。还发现，无论初始临床病程如何，CT都是进行可靠预后预测的有用工具。
