Uterine peristalsis has been evaluated using cine MRI, but it was only at sagittal plane. We tried to evaluate this movement both on sagittal and coronal plane on 3T at pre-ovulation usinig cine MR. There were no significant differences in frequency of peristaltic waves between each walls of sagittal and coronal plane. However, peristaltic direction and outer myometrial conduction of low signal intensity were more recognized in coronal plane than sagittal plane. Although there may be no relation between laterality of ovulation and peristaltic movement, more population is necessary for evaluation.
