This paper discusses the application of CT, MR imaging, and 131I-6 beta-iodomethyl-19-norcholesterol scintigraphy in establishing the nature of incidentally discovered adrenal masses. It is concluded that CT and MR imaging can permit confident differentiation between nonhyperfunctioning adenomas and metastases in cases of incidentalomas that meet all the criteria of a nonhyperfunctioning adenoma. In cancer patients, fine-needle aspiration biopsy of lesions is, in general, essential because a definitive diagnosis of metastatic disease is crucial to disease management. MR imaging and norcholesterol scintigraphy are useful if a relative contraindication for fine-needle biopsy exists or when biopsy results are inconclusive in patients with a presumably benign lesion.
本文探讨了CT、磁共振成像（MR）及131I-6β-碘甲基-19-去甲胆固醇闪烁扫描术在确定偶然发现的肾上腺肿块性质方面的应用。得出的结论是，对于符合无功能腺瘤所有标准的偶然瘤病例，CT和MR成像能够可靠地区分无功能腺瘤与转移瘤。对于癌症患者，一般来说，对病变进行细针穿刺活检至关重要，因为转移性疾病的确切诊断对疾病管理至关重要。如果存在细针活检的相对禁忌证，或者在可能为良性病变的患者中活检结果不明确时，MR成像和去甲胆固醇闪烁扫描术会很有用。
