Magnetic resonance imaging (MRI) of the adrenals was performed on 50 subjects: 5 normal volunteers, 6 Cushing patients with bilateral adrenal hyperplasia, 14 patients with adrenal adenomas, 3 with adrenal carcinomas, 15 with pheochromocytomas and 7 with metastatic disease to the adrenal. The normal and hyperplastic adrenal glands were imaged in all cases. Using the signal intensity of the adrenals on a T2 weighted image, various forms of adrenal pathology could be differentiated. A ratio of signal intensity of the adrenal mass to the liver was utilized and allowed the differentiation of adrenal adenomas from adrenal carcinomas, pheochromocytomas and metastases. Using the same ratio, metastases could be distinguished from pheochromocytomas as well. MRI appears to be particularly valuable in distinguishing clinically silent adrenal metastases from nonfunctioning adrenal adenomas.
对50名受试者进行了肾上腺磁共振成像（MRI）检查：5名正常志愿者、6名患有双侧肾上腺增生的库欣病患者、14名肾上腺腺瘤患者、3名肾上腺癌患者、15名嗜铬细胞瘤患者和7名肾上腺转移瘤患者。所有病例均对正常和增生的肾上腺进行了成像。利用肾上腺在T2加权图像上的信号强度，可以区分各种形式的肾上腺病变。采用肾上腺肿块与肝脏的信号强度比值，可将肾上腺腺瘤与肾上腺癌、嗜铬细胞瘤及转移瘤区分开来。使用相同的比值，也可将转移瘤与嗜铬细胞瘤区分开来。MRI在鉴别临床上无症状的肾上腺转移瘤与无功能肾上腺腺瘤方面似乎特别有价值。
