We evaluated cine MR findings of the uterus in 7 patients with dysmenorrhea associated with endometriosis, changes of these findings after treatment of low dose contraceptives (LOC), with association of these findings with degree of pain. Pre/post-treatment MRI were obtained with 60 image/3 min in a midsagittal plane of the uterus using HASTE sequence, displayed in cine mode to evaluate JZ thickness, endometrial distortion, and frequency of peristalsis. After treatment, endometrial distortion, peristalsis frequencies, and degree of pain were significantly decreased. Endometrial distortion were mildly associated with pain. Cine MRI may be a promising tool in this context.
