目的:探讨MRI评价子宫动脉栓塞治疗子宫肌瘤的疗效及优点。方法:选择性动脉栓塞,注入PVA颗粒。术前、术后3个月、术后6个月行MRI检查。结果:采用核磁复查,75个肌瘤术前体积为108.6 cm3(范围4.2~256.7 cm3),肌瘤3个月平均缩小率为44.6%,6个月平均缩小46.4%。T1WI上肌瘤信号50个为极低信号,19个为低信号,6个为稍高信号;T2WI上肌瘤信号69个为极低信号,6个为稍低信号。结论:MRI有助于评价UAE治疗子宫肌瘤的体积变化和血供改变。
Objective: To evaluate the efficacy and advantages of MRI in the treatment of uterine fibroids by uterine artery embolization. Methods: Selective arterial embolization, injection of PVA particles. Preoperative, postoperative 3 months, 6 months after the line MRI examination. Results: The nuclear volume of 75 fibroids was 108.6 cm3 (range 4.2 ~ 256.7 cm3). The average reduction rate of fibroids in 3 months was 44.6% and 46.4% on average in 6 months. Fifty of the 50 myofilamentary signals on T1WI were very low, 19 were low, and 6 were slightly higher; on the T2WI, 69 were low and 6 were slightly low. Conclusion: MRI is helpful to evaluate the volume change and blood supply changes of uterine fibroids treated by UAE.
