目的：正确认识健康育龄妇女子宫周期MRI影像表现，为患者预约最佳生理周期检查时间，以便获取更精准的子宫影像资料。方法采用高分辨T2WI序列对无子宫疾病且月经周期规律的30名年龄21~35岁健康志愿者，进行月经期(第1天)、增生期(第14天)及分泌期(第28天)的子宫MRI扫描。总结分析不同生理周期子宫结合带宽度及子宫肌层信号特征。结果子宫结合带的宽度于月经期、增生期和分泌期依次递减，子宫肌层的信号强度于月经期、增生期和分泌期依次递增；在月经期，子宫有类似腺肌症的征象，在分泌期，子宫各层的显示更为清晰。结论在分泌期对子宫进行MRI检查，能更清晰地分辨子宫的各层结构，提高诊断子宫疾病的准确率。

Objective To understand the MRI findings of normal uterus in reproductive age female during different stages, and to select the optimal inspection time for patients, so as to gain the more accurate MRI findings of normal uterus. Methods Thirty healthy volunteers of reproductive age, all with regular menstrual cycles, underwent uterine MRI scanning with high resolution T2WI sequence in the menstrual phase (the first day of menstrual cycle), the proliferative phase (the 14th day of menstrual cycle) and the secretory phase (the 28th day of menstrual cycle). The thickness of uterine junctional zone and signal features of myometrium in different physiological cycles were analyzed. Results The thickness of uterine junctional zone were decreased from menstrual phase and proliferative phase to secretory phase, while the signal intensity of myometrium were increased from menstrual phase and proliferative phase to secretory phase. In menstrual phase, the uterine junctional zone showed symptoms of similar adenomyosis, the layers of uterus in secretory phase were clearer than those in the other two phases. Conclusions The layers structures of uterus can be distinguished clearly in secretory phase. Patients should undergo MRI scanning in secretory phase, which can improve the diagnostic accuracy of uterine diseases.
