In this study, we aimed to investigate susceptibility changes related to microvascular invasion (MVI) of hepatocellular carcinoma. We applied liver quantitative susceptibility mapping to measure lesions’ susceptibility. Significant differences in both tumorous and peritumoral susceptibility values were observed for MVI positive and negative lesions. With these findings, QSM imaging can be considered a potential technique for noninvasive preoperational assessment of MVI in hepatocellular carcinoma.
