【摘要】：目的:利用MRI评价健康育龄期未育女性子宫的影像表现及其在不同月经周期的变化等。方法:利用西门子1.5T磁共振对100名月经规律的健康育龄期未育女性行盆腔扫描,测量子宫正中矢状位宫底部及宫体前后壁肌层厚度、子宫内膜厚度并利用单因素方差分析法分析其在不同月经周期的变化,同时评估子宫的倾斜度及弯曲度。结果:测量处子宫底部肌层厚度为(1.18±0.22)cm,子宫前后壁肌层厚度分别约为(1.44±0.24)cm、(1.37±0.32)cm,宫底部肌层较宫体部薄,子宫前后壁肌层厚度无明显差异。子宫内膜自卵泡期、排卵期、黄体期逐渐增厚,厚度分别约为(0.58±0.19)cm、(0.92±0.25)cm、(1.21±0.26)cm。在100名健康志愿者中子宫前倾62例,直立位27例,后倾11例;前屈位62例,平直位6例,后屈32例。结论:明确健康育龄期未生育的女性子宫肌层及内膜厚度及其位置,可以与生育后女性子宫作对比并可为磁共振波谱的研究感兴趣容积的设置提供依据。
[Abstract]:Objective: to evaluate the imaging manifestations of unfertile women and their changes in different menstrual cycles by MRI. Methods: pelvic scans were performed on 100 unfertile women with normal menstrual cycle by Siemens 1.5T magnetic resonance imaging. The thickness of myometrium and endometrium in the medial sagittal position of uterus and the anterior and posterior wall of uterine body were measured, and the changes in menstrual cycle were analyzed by single factor variance analysis. Results: the thickness of myometrium at the bottom of uterus was 1.18 卤0.22 cm, the thickness of muscular layer of anterior and posterior wall of uterus was 1.44 卤0.24 cm and 1.37 卤0.32 cm, respectively. The myometrium of the bottom of uterus was thinner than that of uterine body. There was no significant difference in the thickness of myometrium between anterior and posterior wall of uterus. The thickness of endometrium increased gradually from follicular phase, ovulation stage and luteal phase, and the thickness was 0.92 卤0.25 cm ~ (-1) 卤0.26 cm ~ (-1) respectively. In 100 healthy volunteers, there were 62 cases of anteversion of uterus, 27 cases of upright position, 11 cases of retroversion, 62 cases of anterior flexion, 62 cases of anterior flexion, 62 cases of anterior flexion, 62 cases of anteversion of uterus, 27 cases of vertical position and 11 cases of retroversion. Conclusion: the thickness and location of the myometrium and endometrium of healthy childbearing women were determined in 6 cases of straight position and 32 cases of retroflexion. It can be compared with the female uterus after birth and can provide the basis for the setting of the volume of interest in the study of magnetic resonance spectroscopy.
