| 摘 要： | 目的研究垂体瘤的MRI检查技术并分析其MRI表现。方法对96例垂体瘤病人行MRI检查，应用0．3T永磁成像系统分别做轴位T1、T2加权及矢、冠状面T1加权成像。结果垂体巨腺瘤84例，微腺瘤12例。MRI诊断与最终诊断符合率为100％。86％（72／84）的巨腺瘤在T1WI上为中低信号，81％（68／84）在T2WI是高信号。结论MRI检查定位准确，诊断正确率高，是检查诊断垂体瘤的理想工具。

| Abstract: | Objective To study the MRI scanning method and analyze the MRI expressions of pituitary tumor. Methods Ninety-six cases of pituitary tumor patients were examined under 0. 3 Tesla permanentmagnet scanner,both TIWI and TZWI images and TIWI image on sagittal and coronal sections were obtained. Results Among 96 cases, 84 were macro-adenoma,and the other 12 were micro-adenoma. The correspondency between MRI and clinical diagnosis was 100%. 86% of macro-adenomas showed moderate hypointensity on T1WI and 81% showed hyperintensity on T2WI. Conclusion MRI has a high accuracy of localization and diagnosis on pituitary tumor,thus it is and ideal diagnostic method of pituitary tumor. |
