Characteristics of malignant adrenal masses on CT include tumors of at least 5 cm in size, irregular margins, heterogeneity/necrosis, high CT attenuation (>20 HU), delayed contrast washout <50% ...

A total of 165 adrenal lesions were found, with 139 lesions (84%) ultimately determined as benign and 26 lesions (16%) as malignant. The analysis of the unenhanced CT demonstrated a mean diameter ...

Between 2012 and 2016, researchers at Japan's Okayama University studied 1807 image sets from 168 pathologically diagnosed small (≤ 4 cm) solid renal masses with four CT phases -- unenhanced ...
