Core tip: This manuscript deals with tumor imaging characterization in patients with adrenal tumors; in particular, we discuss our results obtained in three different groups of patients with incidentalomas, adenomas and pheochromocytomas; on the basis of our experience, nuclear imaging modalities using different radiotracers such as labeled nor-cholesterol, metaiodobenzylguanidine and fluorine-deoxy-glucose are able to better characterize, compared with magnetic resonance (MR), adrenal tumors; the functional as well as metabolic features of radionuclide imaging, compared to anatomical characteristics of MR, may explain the better performance of nuclear imaging in characterizing adrenal tumors.
