摘要

一项回顾性研究对267名连续被送去评估一次或多次癫痫发作的患者进行了MRI和CT扫描。21%(57267)的MRI扫描异常。在这些MRI记录的异常病例中，28%的CT扫描正常。在另外10%的病例中，MRI比CT扫描更具特异性。CT对钙化和脓肿的特异性更强(7%)。有一例病理不确定，CT显示异常，尽管MRI正常。MRI上的主要异常包括肿瘤、梗死和血管畸形。MRI在发现癫痫患者中枢神经系统病理和潜在治疗意义的病变方面比CT更敏感。

MRI in epilepsy

A retrospective study was done of the MRI and CT scans of 267 consecutive patients sent for an evaluation of one or more seizures. 21% ( $57267$ ) of the MRI scans were abnormal. The CT scan was normal in 28% of these MRI documented abnormal cases. In an additional 10% of these cases, MRI was more specific than CT scan. CT was more specific in cases of calcification and abscess (7%). There was one case of undetermined pathology in which CT was abnormal despite a normal MRI. The predominant abnormalities found on MRI included tumor, infarction and vascular malformation. MRI is more sensitive than CT in noting central nervous system pathology and lesions of potential therapeutic significance in patients with seizures.
