Predictive Value of IVIM-DWI Parameters Combined with DCE-MRI Parameters for Recurrence After Transcatheter Ar-terial Chemoembolization Treatment in Patients with Hepatocellular Carcinoma
Objective To explore the predictive value of intravoxel incoherent motion diffusion-weighted imaging(IVIM-DWI)parameters combined with dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)parameters for recurrence after transcatheter arterial chemoembolization(TACE)treatment in patients with hepatocellular carcinoma.Methods According to the recurrence situation,160 patients with hepatocellular carcinoma who were effective in TACE treatment were divided into the recurrence group and the non-recurrence group.The IVIM-DWI parameters(D,D*,ADC)and DCE-MRI parameters(Ktrans,Kep,Ve)of the two groups were compared,and the predictive value of the relevant parameters for the recurrence of patients with hepatocellular carcinoma after TACE treatment was analyzed.Results The D of the recurrence group was lower than that of the non-recurrence group,and the D*,Ktrans and Kep were higher than those of the non-recurrence group(P＜0.05).ROC curve showed that the combination of D*,D,Ktrans and Kep had good predictive value for recurrence after TACE treatment in patients with hepatocellular carcinoma(AUC=0.814).Conclusions IVIM-DWI parameters combined with DCE-MRI parameters can effectively predict the recurrence of patients with hepatocellular carcinoma after TACE treatment.
