The MR appearance of normal and pathological meninges was studied in 23 patients. Amongst twelve normals, T1-weighted images demonstrated the meninges as slightly hyperintense density structures (compared with CSF) which increased in signal intensity somewhat after the administration of gadolinium-DTPA. On T2-weighted images, the subarachnoid space and meninges were isointense. In eleven patients with inflammatory disease or tumourous infiltration of the meninges, abnormal findings were evident in the unenhanced images as well as after administration of gadolinium-DTPA. Compared with CT, MR proved greatly superior in the diagnosis of meningeal abnormalities.
对23例患者的正常和病理性脑膜的磁共振成像表现进行了研究。在12例正常患者中，T1加权图像显示脑膜为略高信号密度结构（与脑脊液相比），注射钆-DTPA后信号强度有所增加。在T2加权图像上，蛛网膜下腔和脑膜呈等信号。在11例患有脑膜炎症性疾病或肿瘤浸润的患者中，未增强图像以及注射钆-DTPA后均有明显异常表现。与CT相比，磁共振成像在脑膜异常的诊断中显示出极大的优越性。
