We assessed the frequency of stroke diagnostic errors revealed by CT in 197 patients. In five patients, CT was an emergency procedure. In the other 192 patients, CT was used to check diagnosis based on routine investigations. All but eight diagnoses (4%) were thereby confirmed. Either hemorrhage was discovered where an ischemic lesion had been suspected (2 cases) or the reverse (3 cases). Disorders other than stroke were found in three patients--subdural hematoma, hydrocephalus, and suspected tumor. Thus, few but important errors were revealed by the CT investigations.
我们评估了197例患者中CT所揭示的中风诊断错误的发生率。其中5例患者进行CT检查属于急诊情况。在另外192例患者中，CT用于基于常规检查结果来核实诊断。除8例诊断（4%）外，其余诊断均得到了证实。出现了2例在怀疑为缺血性病变处发现出血的情况，以及3例相反的情况（在怀疑为出血处发现缺血性病变）。在3例患者中发现了非中风性疾病——硬膜下血肿、脑积水和疑似肿瘤。因此，CT检查揭示的错误虽少，但很重要。
