Magnetic resonance imaging (MRI) of the brain was performed in 18 patients with non-epileptiform basilar artery migraine (BAM). In a few subjects, mild enlargement of the cortical sulci and white matter T2 weighted increased signal intensity were present. Twelve of the patients also underwent computerized tomography (CT) of the head: 6 of the latter individuals had abnormalities on their MRI not detected by CT, but their finding did not modify the pre-existing diagnosis or influence clinical management. No evidence of biologic markers (i.e. congenital anomalies of the brainstem) was encountered and no signs of prior traumatic lesions, demyelinating disease or complicating stroke. MRI is a useful but limited complementary diagnostic tool in BAM.
对18例非癫痫样基底动脉型偏头痛（BAM）患者进行了脑部磁共振成像（MRI）检查。在少数受试者中，存在轻度的脑沟增宽和白质T2加权信号强度增加。其中12例患者还接受了头部计算机断层扫描（CT）：在这12例患者中，有6例患者的MRI异常未被CT检测到，但这些发现并未改变先前的诊断或影响临床治疗。未发现生物学标志物（即脑干先天性异常）的证据，也未发现既往创伤性病变、脱髓鞘疾病或并发中风的迹象。MRI是BAM中一种有用但有局限性的辅助诊断工具。
