Lipiodol deposition after CT-RFA. (A) Uniformity of lipiodol deposition using CT plain scanning; (B) high blood perfusion in lipiodol sparse region by HAP map; (C) no blood perfusion in lipiodol concentrated region by PVP map; and (D) blood perfusion in lipiodol sparse region by HPI map. CT = computed tomography, CT-RFA = CT-guided radiofrequency ablation, HAP = hepatic arterial perfusion, HPI = hepatic perfusion index, PVP = portal vein perfusion.
