PurposeTo compare diagnostic performance of unenhanced and CTA images (Image set 1) to that of combined unenhanced, CTA, and venous-phase images (Image set 2) for incidentalomas in patients with aortic aneurysm.MethodsPreoperative CT Images of consecutive 240 patients were reviewed by two observers for incidentalomas. Diagnostic performance was assessed.ResultsSensitivity was higher in Image set 2 than Image set 1 in observer 1 and overall (P=0.03 and 0.00). AUCs for both observers were higher in Image set 2 than Image set 1 (P=0.03 and 0.01).ConclusionAddition of venous-phase to CTA significantly improved diagnostic performance of incidentalomas.
