摘要 目的探讨MRI对肾上腺疾病的诊断价值。方法收集53例肾上腺疾病患者MRI检查资料,分析肾上腺增生、囊肿、腺瘤、嗜铬细胞瘤及肾上腺皮质腺癌、转移性肿瘤的MRI表现,并与临床症状、实验室资料相结合。结果肾上腺疾病与其形态变化密切相关,增生、囊肿、腺瘤具有较特征性MRI表现,可通过MRI检查确诊,但无功能腺瘤、原发性醛固酮增多症及其它腺瘤仅靠影像检查不能区分,应结合临床症状及实验室资料进行诊断;肾上腺皮质腺癌、转移性肿瘤及嗜铬细胞瘤MRI表现相似,均可表现为较大的分叶状、不规则形肿块,信号混杂,内部有出血、坏死、囊变及钙化,要结合其各不相同的临床症状进行鉴别。结论 MRI具有较高的信噪比及分辨率,可直观显示肾上腺的形态学改变,可为临床诊断提供充足证据。
