[Role of imaging in the evaluation and characterization of adrenal masses].

The primary role of imaging in identification as well as in characterization adrenal lesions has been demonstrated by several studies. The recent technologic progress has allowed to identify adrenal lesions even when they are very small, with a consequent conspicuous increase of the frequency of incidentalomas. Computed Tomography, Magnetic Resonance and Nuclear Medicine are routinely used to evaluate adrenal glands and their pathologic conditions. The aim of this article is to show how the imaging is employed to assess adrenal masses, with special regard to the contribution given by Computed Tomography (CT) and Magnetic Resonance (MR) imaging to the differential diagnosis between benignant and malignant lesions.
