摘　　要：目的 :探讨脑干肿瘤MRI的诊断价值。材料与方法 :对 10例脑干肿瘤患者行常规TSE序列、水抑制成像及Ga DTPA增强扫描 ,并与手术病理进行对照。结果 :7～ 13岁为该病好发年龄 ,桥脑为常见部位。MRI特征为脑干增粗、信号异常、占位效应、基底动脉包绕症及脑水肿、脑积水等。结论 :MRI是目前脑干肿瘤检查的最佳方法 ,可为诊断与手术适应证的选择。Purpose:To evaluate MRI in the diagnosis of brainstem tumors Material and Methods: The MRI data of 10 cases of brainstem tumors proved by pathology were analysed and correlated with pathologic findings. All patients had Gd DTPA enhancement. Results: The main abnormalies demonstrated by MRI included brainstem changed large、mass effect、mild edema and focus degeneration or necrosis. Conclusion: MRI scans can provide reliable images for diagnosis of brainstem tumors, and have important significance in improving diagnosis and operation of the patients with brainstem tumors.
