Abstract
Purpose
This study aimed to compare the image quality and adverse events between Iopamidol 250 and Ioversol 320 usage during transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).
Materials and Methods
Medical records and hepatic angiography from 113 patients who un-derwent TACE with Iopamidol 250 (44 patients) and Ioversol 320 (69 patients) were retrospective-ly reviewed. Vessel perception on hepatic angiography was graded into three categories by two radiologists for hepatic subsegmental arteries, the right gastroepiploic artery, right gastric artery, and pancreaticoduodenal artery. Imaging concordance was assessed by comparing the number of detected HCCs on hepatic angiography and CT. The adverse events before and after hepatic angiography were evaluated.
Results
The mean vessel perception scores were 2.92 and 2.94 for Iopamidol 250 and Ioversol 320, respectively. The imaging concordance was 31 (70.5%) and 46 (66.7%) patients for Iopamidol 250 and Ioversol 320, respectively. There were no statistical differences in vessel perception or imaging concordance (p > 0.05). One and six patients experienced nausea for Iopamidol 250 and Ioversol 320, respectively. There was no statistical difference in adverse events (p = 0.24).
