本文报告了３８例手术证实的桥小脑角肿瘤的ＭＲ表现。结果表明，ＭＲＩ不仅具有精确的术前定位能力，而且能够对多数肿瘤进行定性诊断，术前定性诊断的正确率为９０．２％。分析了肿瘤的ＭＲＩ特征，认为肿瘤的信号和形态改变结合在肿瘤定性诊断中有重要意义。Ｇｄ—ＤＴＰＡ增强扫描有助于肿瘤的定住。基于ＭＲＩ在桥小脑角肿瘤诊断中具有精确的发现、定位和定性能力，对临床可疑桥小脑用肿瘤病人，ＭＲＩ是首选的影像诊断方法。
This article reports the MR findings of 38 surgically-treated cerebellopontine angle tumors. The results show that MRI not only has accurate preoperative localization ability, but also can make qualitative diagnosis of most tumors. The correct rate of preoperative qualitative diagnosis is 90.2%. Analyze the MRI features of the tumor, that the combination of tumor signal and morphological changes in the qualitative diagnosis of tumors is of great significance. Gd-DTPA enhanced scan helps to fix the tumor. Based on MRI in the diagnosis of cerebellopontine angle tumor with accurate discovery, localization and qualitative ability, clinical suspected cerebellar tumor patients, MRI is the preferred imaging diagnosis method.
