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、手术入路等提供可靠的依据
Objective: To explore the diagnostic value of MRI in brain stem tumors. Materials and Methods: Ten cases of brain stem tumor patients underwent routine TSE sequence, water-suppressed imaging and enhanced Ga DTPA scanning, and compared with the surgical pathology. Results: 7 to 13 years old for the incidence of the disease age, pons the brain is a common site. MRI features thickening of the brain stem, signal abnormalities, mass effect, basilar artery embolism and cerebral edema, hydrocephalus. Conclusion: MRI is the best method for the diagnosis of brain stem tumors at present, which can provide a reliable basis for the diagnosis and selection of surgical indications and surgical approaches
