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 investigate the MRI findings of uterine fibroids before and after uterine artery embolization. Methods Eighty-seven patients with uterine fibroids underwent uterine arterial embolization. The levels of fibroids, location, size and MRI signals were observed at 3 to 14 days before operation and 3 months to 6 months after operation. Intensity and myometrial signal changes. Results After uterine arterial embolization, the average size of fibroids decreased by 64.3%. The signal intensity of T2WI decreased in 175 (94.6%) of the patients. There was no enhancement of 175 tumors (94.6%) in enhanced scan and disappearance of 4 tumors. Conclusion MRI can monitor the volume change, necrosis and blood supply of fibroids after embolization, guide the clinical treatment and judge the curative effect.
