[Abstract] Objective: To evaluate the immediate value of dynamic contrast-enhanced MRI(DCE-MRI)quantitative parameters after HIFU treatment of uterine fibroids.Materials and Methods: Thirteen patients with uterine fibroids were scanned with DCE-MRI before and after HIFU ablation. They were grouped into two groups, the complete ablation group and the non-complete ablation group according to appearance of DCE-MRI. Mann-Whitney U test and Spearman's correlations were applied to find the association between quantitative parameters and grouping.Results: Ktrans(after treatment), Ve (after treatment) and Vp (after treatment) were positively correlated with the grouping, and correlation coefficents were 0.713 , 0.757 and 0.668 respectively. Ktrans(rate of change) and Ve(rate of change) were negatively correlated with the grouping, and correlation coefficients were both-0.802.Conclusion: DCE-MRI quantitative parameters have reference value in HIFU treatment's immediate effect evaluations for uterine fibroids.
