摘要 目的:探讨健康女性子宫肌层在不同月经周期的厚度、信号强度及表观弥散系数值的变化。方法:采用3.0T MRI分别于增殖中期、分泌晚期、月经期对36例年轻健康女性行3次子宫MR检查,研究子宫体、子宫颈肌层在不同月经周期的厚度、T2WI信号强度及ADC值变化。结果:(1)宫体肌层、结合带厚度于增殖期、分泌期与月经期有明显差异;宫颈肌外层厚度于月经周期各期无明显差异;(2)宫体肌层、结合带的信号强度在月经期与分泌期间存在差异;宫颈基质环的信号强度在增殖期与月经期间存在差异,增殖期、月经期宫颈肌外层的信号强度与分泌期相比均存在差异;(3)宫体肌层及宫颈肌外层的ADC值在月经周期各期间无明显差异,增殖期、分泌期的宫体结合带ADC值与均与月经期间存在差异;宫颈基质环ADC值在增殖期与分泌期间存在差异。结论:不同的月经周期中,子宫各肌层的厚度、信号强度及ADC值均存在不同程度的差异。在诊断不同类型的子宫疾病时应充分考虑到这些因素,以达到选择正确的检查时间窗的目的。
