目的 分析脑膜癌病的磁共振成像表现 ,探讨MRI对脑膜癌病的诊断价值。方法 回顾性分析 2 5例脑膜癌病的磁共振资料。结果 MRI平扫SE序列T2 WI 11例阳性 ,T1WI 8例阳性 ,增强后T1WI 2 5例阳性。按Meltzer等的标准 ,依据增强MRI表现把脑膜癌病分为 2型 :硬脑膜 -蛛网膜型 7例 ;软脑膜 -蛛网膜下腔型 18例。结论 MRI扫描 ,特别是增强扫描是诊断脑膜癌病的最佳手段 ,双倍造影剂及薄层扫描能提供更多的信息
Objective To analyze the MRI findings of meningeal carcinomatosis and to evaluate the diagnostic value of MRI in meningeal carcinomatosis. Methods The MRI data of 25 cases of meningeal carcinomatosis were retrospectively analyzed. Results 11 cases were positive in T1 WI and 8 cases were positive in T1WI. According to Meltzer and other criteria, according to enhanced MRI manifestations of meningeal cancer is divided into 2 types: dura-arachnoid type in 7 cases; pial-subarachnoid type in 18 cases. Conclusions MRI scans, especially enhanced scans, are the best means of diagnosing meningeal carcinomatosis and double contrast media and thin-layer scanning provide more information
