Submucosal leiomyoma is one of the most recognized causes of infertility. We aim to evaluate uterine peristalsis in patients with uterine leiomyomas using kinematic MR imaging. We performed kinematic HASTE MR imaging of the midsagittal plane of uterus in 26 patients with leiomyoma, and evaluated peristaltic movements at the endometralmyometrial junction and focal myometrial movements adjacent to leiomyomas. Uterine peristaltic movement were partly interrupted by submucosal leiomoymas, but not by myometrial or subserosal leiomyomas. Focal myometrial movements was noted only adjacent to submucosal leiomyomas. These findings are considered to represent dysfunctional contractility, and may be related with pregnancy loss.
