With the steep increase in the use of cross-sectional imaging in recent years, the incidentally detected adrenal lesion, or "incidentaloma", has become an increasingly common diagnostic problem for the radiologist, and a need for an approach to classifying these lesions as benign, malignant or indeterminate with imaging has spurred an explosion of research. While most incidentalomas represent benign disease, typically an adenoma, the possibility of malignant involvement of the adrenal gland necessitates a reliance on imaging to inform management decisions. In this article, we review the literature on adrenal gland imaging, with particular emphasis on computed tomography, magnetic resonance imaging, and photon-emission tomography, and discuss how these findings relate to clinical practice. Emerging technologies, such as contrast-enhanced ultrasonography, dual-energy computed tomography, and magnetic resonance spectroscopic imaging will also be briefly addressed.
近年来，随着横断面成像技术的使用急剧增加，偶然发现的肾上腺病变，即“肾上腺意外瘤”，已成为放射科医生越来越常见的诊断问题，并且需要一种通过成像将这些病变分类为良性、恶性或不确定的方法，这刺激了大量的研究。虽然大多数肾上腺意外瘤代表良性疾病，通常是腺瘤，但肾上腺发生恶性病变的可能性使得必须依靠成像来为管理决策提供依据。在本文中，我们回顾了有关肾上腺成像的文献，特别强调计算机断层扫描、磁共振成像和正电子发射断层扫描，并讨论这些检查结果如何与临床实践相关。新兴技术，如超声造影、双能量计算机断层扫描和磁共振波谱成像也将简要提及。
