Abstract

Objective To demonstrate and evaluate uterine peristalsis on cine magnetic resonance imaging (MRI) using ultrafast imaging. Methods Between September 2014 and December 2014, a total of fifty-five volunteers were underwent cine MR imaging over 360 seconds and videotaped at the speed of ten times. Two radiologists independently evaluated videotapes of 98 studies. Results Uterine peristalsis is found depending on menstrual cycle phase.It is most active during periovulatory phase from cevico to fudal at the speed of 12.48 times every 6 minutes.It is most inactive during luteal phase at the speed of 1 time every 6 minutes.Uterine peristalsis during menstrua phase is from fudal to cervico at the speed of 3.55 times every 6 minutes. Conclusion Uterine peristalsis was demonstrated on cine MR using ultrafast MRI. Direction and frequency of peristaltic waves are closely related to menstrual cycle phases
