Synopsis

Keywords: Liver, Diffusion/other diffusion imaging techniques, IVIMThe accurate evaluation of tumor response after Transarterial Chemoembolization (TACE) treatment is important for tumor prognosis and subsequent treatment. In this study, we comprehensively investigated the feasibility of IVIM parameters in the TACE treatment area, peritumoral area, and hepatic parenchymal to predict tumor recurrence in hepatocellular carcinoma patients after TACE treatment. ADC and D of TACE-treated area, and D of the peritumoral area can predict the intralesional and peritumoral recurrence after TACE treatment with high accuracy, indicating that IVIM might be a useful tool in predicting the therapeutic response and the peritumoral invasion.
