摘要: 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。

Abstract: Objective: To evaluate the therapeutic efficacy of uterine artery embolization for leiomyoma by MRI. Methods: Seventeen patients with leiomyoma (39 leiomyomas) undergone uterine artery embolization with Seldinger′s method were enrolled and the indices of uterine leiomyoma were recorded, including volume, major axis, number, signals and ADC on magnetic resonance imaging before and 3 months,6 months after the procedure as well as the clinical symptoms. Results: The average volume of 39 leiomyomas was reduced by 79.72%. Meanwhile, the average of total major axis was reduced by 44.92%. And the symptoms of 9 patients with menorrhagia improved markedly, the symptoms of 7 of the 9 patients with severe dysmenorrhea relieved dramatically. After treatment, signal intensity on T1WI imaging was increased in 84.62% lesions, while ADC values were decreased in 82.05% lesions. Conclusions: MRI is a preferable approach to evaluate the efficacy of uterine artery embolization.
