Abstract

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.
