作者在一个完整的月经周期内每周两次从六名健康女性身上获取矢状磁共振 (MR) 图像，以确定子宫各层的变化。使用并行内分泌和超声研究来精确确定排卵日。在月经周期期间，所有受试者的子宫内膜和子宫肌层的厚度和强度均出现一致的变化。子宫肌层厚度和子宫内膜面积在周期的卵泡（排卵前）阶段线性增加；黄体期增加率显着下降。观察到两个子宫肌层；在周期的前半段展示了各层之间的最佳对比度。
The authors obtained sagittal magnetic resonance (MR) images twice a week from six healthy women during one full menstrual cycle to establish the changes depicted in the uterine layers. Parallel endocrine and ultrasound studies were used to establish the day of ovulation precisely. Consistent changes in the thickness and intensity of the endometrium and myometrium were noted in all subjects during the menstrual cycle. Both myometrial thickness and endometrial area increased linearly during the follicular (preovulatory) phase of the cycle; the rate of increase dropped significantly during the luteal phase. Two myometrial layers were observed; the best contrast between the layers was demonstrated during the first half of the cycle.
