目的研究垂体大腺瘤的MRI平扫及增强表现,探讨MRI增强扫描对垂体大腺瘤的诊断价值。方法回顾性分析24例经手术及病理证实的垂体大腺瘤的MRI平扫及增强表现。结果 T1加权成像等信号18例,略低信号5例,等、高混杂信号1例。T2加权成像等信号20例,等、高混杂信号4例。增强后垂体瘤均见不同程度的强化。结论磁共振增强扫描在垂体大腺瘤的定性、定位诊断上具有及其重要的应用价值。
Objective To study the MRI findings of pituitary adenoma by MRI and to explore the diagnostic value of MRI enhanced pituitary adenoma. Methods Retrospective analysis of 24 cases of pituitary adenoma confirmed by surgery and pathology were performed plain MRI and enhanced manifestations. Results T1 weighted imaging signal 18 cases, slightly lower signal in 5 cases, and so on, high mixed signal in 1 case. T2 weighted imaging signals such as 20 cases, and so on, high mixed signal in 4 cases. Enhanced pituitary tumors were seen to varying degrees of enhancement. Conclusion Magnetic resonance enhanced scan has great value in the diagnosis and localization of pituitary adenoma.
