摘　　要：目的讨论3.0T磁共振(MR)在颅咽管瘤诊断中的应用价值。方法对我院7年间入院的41例颅咽管瘤患者的磁共振成像(MRI)图像进行回顾性诊断分析,所有患者均经手术病理证实,总结颅咽管瘤的MRI特点。结果 41例患者中,有19例患者MRI T1WI呈低信号、T2WI高信号;12例T1WI呈现高信号、T2WI高信号;8例患者T1WI为等信号、T2WI高信号;2例患者T1WI为低信号、T2WI低信号。增强后所有患者实性部分均出现明显强化,囊性部分均无强化,但出现囊壁强化。结论颅咽管瘤的MRI诊断具有较高的准确率,掌握对本病MRI信号的认识,利于在疾病的早期作出准确的诊断。Objective To discuss the application value of 3.0TMRI in the diagnosis of craniopharyngioma. Methods Selected 41 cases of MRI images with craniopharyngioma patients through 7 years in our hospital for retrospective diagnostic analysis, all the patients were confirmed by pathology. Summarized the characteristics of magnetic resonance imaging of craniopharyngioma. Results In 41 patients, MRI T1WI imaging of 19 patients showed low signal, T2WI imaging showed high signal; T1WI imaging of 12 cases showed high signal, T2WI imaging showed high signal; T1WI imaging of 8 patients showed equal signal, T2WI imaging showed high signal; TlWI imaging of 2 patients showed low signal, T2WI imaging showed low signal. Enhanced solid portion of all patients were significantly enhanced. There was no enhancement found in the cystic part but enhancement in the cyst wall. Conclusion MRI diagnosis of craniopharyngioma is of higher accuracy, through mastery of the MRI signal awareness of this disease, it is easy to achieve accurate diagnosis in the early stages oft：he disease.
