摘要 目的探讨通过术前MRI来预测垂体腺瘤质地的临床意义及不同质地垂体腺瘤的手术处理技巧。方法收集本院显微手术治疗的306例大型垂体腺瘤的临床资料,重点调查术前MRI对肿瘤质地的评估结果及不同质地肿瘤的切除情况。采用Iuchi等的方法对肿瘤质地进行评估,即T2加权像肿瘤信号越低,质地越坚韧;信号越高,质地越软。结果T2加权像的信号强度值位于5~30的有38例,30~36有132例,60~100有136例。该结果与术中证实的结果基本相符。质地坚韧、中等及质软者全切除率分别为25%、83.6%、98.4%。结论MRI能够较准确地预测垂体腺瘤的质地,借此选择适当的手术入路及显微切除技术方式对改进治疗效果有重要的意义。
