Pelvic MRI images of the same patient at different phases of the menstrual cycle. Pelvic MRI scans of the same volunteer (28 years old, parity = 1, regular 28-d cycle) were obtained three times during the menstrual cycle. (a) Day 3: menstrual period; (b) Day 14: ovulatory period; (c) Day 21: implantation period. Note the small angle and strong anteversion during the menstrual and implantation periods [(a) red line; (c) green line] and the larger angle with an upright shift during the ovulatory period [(b) yellow line].
