Computed tomography and magnetic resonance imaging features for differentiating functioning from non-functioning adrenal lesions

Abstract

Aim: It is not well known whether the radiological features of adenomas differ between functioning and non-functioning adrenal lesions (NFAL). The aim of this study was to evaluate the characteristic features of computed tomography (CT) and magnetic resonance imaging (MRI) characteristics among functioning and non-functioning adrenal lesions. Material and Methods: This retrospective study included 89 patients with functioning adrenal lesions and 148 patients with NFAL, whose CT or MRI findings were present. Group 1 included patients with functioning adrenal lesions and group 2 patients with NFAL. Results: In patients with functioning adrenal mass, adenoma size (p:0.001), unenhanced and early-enhanced Hounsfield units (HU) (p
