目的对比观察子宫肌瘤子宫动 脉栓塞术(UAE)治疗前后磁共振成像(MRI) 影像学特征。方法 回顾性分析2015年1 月-2017年7月于我院行UAE治疗的45例子 宫肌瘤患者临床资料，均于UAE治疗前行 临床检查及MRI检查，排除手术禁忌症， 并于治疗后1个月内行MRI复查，观察治疗 前后子宫肌瘤MRI信号特点及体积变化。 结果 经UAE治疗后，42例(93.33%)患者月 经恢复正常，另3例月经也有不同程度改 善，无闭经、子宫坏死等严重并发症出 现；45例患者中，单发肌瘤15例，多发30 例，共发现80个子宫肌瘤；治疗后共有68 个(85.00%)肌瘤T1WI序列明显升高，15个 (18.75%)肌瘤T2WI序列明显降低，，72 个(90.00%)肌瘤增强扫描强化程度明显 降低，13个(16.25%)肌瘤DWI序列明显降 低；治疗后肌瘤体积(32.48±21.20)cm3 较治疗前(69.48±30.74)cm3显著减小， 差异有统计学意义(t=8.862，P<0.05)。 结论 MRI是评价子宫肌瘤患者UAE治疗疗 效的重要影像学检查方法。

Objective To compare the magnetic resonance imaging (MRI) features of uterine fibroids before and after uterine artery embolization (UAE). Methods The clinical data of 45 cases of patients with uterine fibroids treated in our hospital from January 2015 -2017 July were retrospectively analyzed. All patients were given clinical examination and MRI examination before UAE so as to exclude surgical contraindications, and were given MRI recheck within 1 month after treatment. The MRI signal features and volume change of uterine fibroids were observed before and after treatment. Results After UAE, there were 42 cases (93.33%) with menstruation returned to normal, and 3 cases with different degrees of improvement, and there were no serious complications such as amenorrhea and uterine necrosis. Among 45 cases, 15 cases were single fibroids and 30 cases were multiple fibroids, and a total of 80 uterine fibroids were found. After treatment, T1WI sequences of 68(85%) fibroids were significantly increased, and T2WI sequences of 15(18.75%) fibroids were significantly reduced, and enhancement degrees of myoma enhanced scan of 72(90%) fibroids were significantly reduced, and DWI sequences of 13(16.25%) fibroids were significantly reduced. After treatment, the fibroid volume was significantly decreased compared with that before treatment [(32.48±21.20) cm3 vs (69.48±30.74) cm3 ] (t=8.862, P<0.05). Conclusion MRI is an important imaging method to evaluate the efficacy of UAE in patients with uterine fibroids.
