目的:探讨MRI检查在子宫动脉栓塞术治疗子宫肌瘤疗效评价中的应用价值。方法:17例临床及影像学检查诊断为子宫肌瘤的患者(39枚肌瘤)采用Seldinger方法行双侧子宫动脉栓塞术,运用MRI常规序列和弥散加权成像(diffusion-weighed imaging,DWI),观察患者治疗前、后(3个月、6个月)病灶体积、长径、数量、信号特点及表观弥散系数(apparent diffusion coefficient,ADC)值的变化,并应用临床症状调查表比较患者治疗前、后的症状。结果:MRI检查显示,治疗后患者的39枚子宫肌瘤体积平均缩小了79.72%,平均长径总和减小44.92%,84.62%的病灶T1WI序列信号强度较治疗前上升,82.05%的病灶的ADC值较治疗前下降。结论:MRI检查可用于监测和评价子宫动脉栓塞术治疗子宫肌瘤后的疗效。
Objective: To investigate the value of MRI in evaluating the curative effect of uterine fibroids in uterine artery embolization. Methods: Seventeen patients diagnosed as uterine myoma (39 fibroids) by clinical and radiological examinations underwent bilateral uterine artery embolization using Seldinger method and conventional MRI and diffusion-weighted imaging (DWI) The change of volume, long diameter, number, signal characteristics and apparent diffusion coefficient (ADC) of the patients before and after treatment (3 months and 6 months) were observed. The patients were treated with the clinical symptom questionnaire Before and after the symptoms. Results: MRI examination showed that the volume of 39 uterine fibroids was reduced by 79.72% on average and the average long diameter was reduced by 44.92%. The signal intensity of T1WI sequence in 84.62% lesions was higher than that before treatment, and 82.05% Value decreased before treatment. Conclusion: MRI can be used to monitor and evaluate the efficacy of uterine artery embolization after uterine fibroids.
