Adrenal adenomas are common due in part to increased utilization of cross-sectional imaging, there is a growing need to evaluate the utility of CT washout for small homogenous adrenal nodules (<4cm) with HU>10 and without history of cancer given the prevalence of malignancy in true incidentalomas is low. Mohanned Alnammi, MD discusses an article that found evaluating true incidentalomas with HU >10 with CT washout and showed suboptimal diagnostic performance and that the 60% washout threshold may be of limited utility in those without a history of cancer.
