Dual-energy computed tomography (DECT). a-d 58-year-old man with 39-mm hepatocellular carcinoma (arrows) imaged with DECT. Arterial phase hyperenhancement is better visualized on iodine map (a) than on the standard late hepatic arterial phase (b). Lesion also shows washout on portal venous (c) and delayed phase (d). e-h 79-year-old man with hepatocellular carcinoma treated with microwave ablation (arrows) and imaged with DECT. Iodine map (e), standard late hepatic arterial phase (f), portal venous (g), and delayed phase (h) demonstrate no residual enhancement consistent with complete tumor treatment
