摘　　要：目的探讨子宫肌瘤子宫动脉栓塞治疗前后的MRI表现。方法对87例子宫肌瘤患者行子宫动脉栓塞治疗,于术前3d^14d,术后3个月~6个月行MRI平扫及增强检查,观察肌瘤数目、部位、大小、MRI信号、强化幅度及子宫肌层信号改变。结果子宫动脉栓塞术后,肌瘤体积平均缩小约64.3%,175个(94.6%)瘤体T2WI信号下降,增强扫描175个(94.6%)瘤体无强化,4个瘤体消失。结论MRI可以监测栓塞术后肌瘤体积变化、坏死及血供情况,指导临床治疗及判断疗效。Objective To explore the MRI appearances of hysteromyoma before and after uterine arterial embolization （UAE）. Methods 87 cases of hysteromyoma were treated by UAE. MRI was performed 3 to 14 days before and 3 to 6 months after embolization. The changes of number.location, volume, signal intensity and blood supply of myoma and signal changes of myometrium were observed. Results The mean reduction in volume of post-UAE myoma was 64.3 % 175 myoma showed the signal on T2 WI reduction and no enhanced on T1 WI, 4 myoma disappeared. Conclusion MRI can evaluate the volume changes,necrosis and the blood supply of the post-UAE myoma, and guide the clinical treatment and decide the response of treatment.
