目的：探讨肾上腺肿块ＭＲＩ信号产生机制，初步评价ＭＲＩ在其诊断中的作用。方法：对５３例患者６７只肾上腺肿块进行ＭＲＩ检查，同时行手术病理或活检病理检查。结果：ＭＲＩ对肿块的检出率为１００％，定位精确；可对大多数肿块作出定性诊断；可以明确肿块与邻近组织结构的关系。结论：肾上腺肿块病理结构是其ＭＲＩ信号变化的基础，ＭＲＩ对肾上腺肿块的定位、定性诊断均有重要作用。
Objective: To investigate the mechanism of MRI signal generation in the adrenal mass and to evaluate the role of MRI in its diagnosis. METHODS: MRI was performed on 67 adrenal masses of 53 patients. Surgical pathology or biopsy was performed at the same time. RESULTS: The detection rate of MRI on the mass was 100%, and the positioning was accurate. The majority of masses could be diagnosed qualitatively; the relationship between the mass and the adjacent tissue structure could be clearly defined. Conclusion: The pathological structure of the adrenal mass is the basis of the MRI signal changes. MRI plays an important role in the localization and qualitative diagnosis of the adrenal mass.
