Distinguishing Benign from Malignant Adrenal Masses: Multi–Detector Row CT Protocol with 10-Minute Delay

Abstract

Precontrast attenuation of less than 0 HU supercedes the washout profile in the evaluation of an individual adrenal mass. Noncalcified, nonhemorrhagic adrenal lesions with precontrast attenuation of more than 43 HU should be considered suspicious for malignancy.
