摘要
Abstract
AbstractObjective: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 andSpearman's correlations were applied to ifnd 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 coefifcents 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 coefifcients were both -0.802.Conclusion:DCE-MRI quantitative parameters have reference value in HIFU treatment's immediate effect evaluations for uterine ifbroids.关键词
