摘要

目的:探讨（Magnetic resonance imaging

MRI）判断垂体腺瘤质地的可能性及其临床价值。方法:收集97例手术、并经病理确诊的垂体腺瘤

根据术中肿瘤质度分为质地软组（71例）

质地中组（14例）和质地韧组（12例）

与术前MRI检查T2WI加权成像的瘤体/桥脑比值（T/P）进行相关分析。结果:3组的T/P值分别为1.681±0.069

1.344±0.082

0.981±0.060

其差异有统计学意义（P<0.01）。结论:术前MRI T2WI的信号强度可判断垂体腺瘤的质地

对选择手术入路、手术困难估计、预后判断及选择合适的后续治疗有重要意义。

Abstract

Objective:To discuss the possibility of MRI evaluation of pituitary adenomas consistency and its significance. Methods:All patients received surgery and pathological examination.In 97 cases

71 cases were sof(tnonfibrous)

14 cases were moderate

12 cases were firm (fibrous).In 97 cases

Preoperative MRI was performed in all cases

Tumor/Pons signal intensity ratio (TPSIR)was measured in T 2 WI.Results:In three groups

T 2 WI Tumor/Pons signal intensity ratio (TPSIR)was 1.681±0.069

1.344±0.082

0.981±0.060;there was significant difference between three groups (P<0.01).The difference was prominent(P<0.01).Conclusion:Preoperative MRI T 2 WI can predict the consistency of pituitary adenomas

which is veryimportant for choice ofsurgical approach and prognosis.
