摘要： 目的 探讨垂体腺瘤核磁共振信号强度与质地之间的关系。方法 研究68例垂体腺瘤患者，统计分析垂体腺瘤质地与核磁共振信号之间的关系。结果 不同质地的肿瘤在T2WI像上信号高低具有显著性差异，而T1WI像上信号高低无显著性差异。结论 术前通过垂体瘤核磁共振信号可以初步判断垂体瘤的质地，为制定手术入路提供重要依据。

    【Abstract】 Objective：To investigate the relationship between MR signal intensit and the hardness of pituitary adenomas. Methods: Analysis the relationgship between MR images and the hardness of pituitary adenomas in 68 patients.Results: There was significant differenct signal on T2WI between pituitary adenomas with different consistence.but There was not differenct signal on T2WI.Conclusion: Through magnetic resonance signal we can predict the hardness of pituitary adenoma before operation and this can provide the best approach to the pituitary adenomas.
