| 目的 观察MRI评价生育与未生育女性髂尾肌形态及功能的价值。方法 对50名健康经产妇（生育组，根据分娩方式分为剖宫产亚组和自然分娩亚组）和17名未生育健康女性（未生育组）于自然状态及增加腹压状态下行MR检查，测量髂尾肌厚度（ICT）、冠状位髂尾肌角（cICA）和矢状位髂尾肌角（sICA），比较两种状态下各组间差异。结果 自然状态下，生育组右侧和双侧平均sICA均大于未生育组（P均<0.05），两组ICT、左右侧及双侧平均cICA、左侧sICA差异均无统计学意义（P均>0.05）；自然分娩亚组双侧平均sICA大于剖宫产亚组（P<0.05）。增加腹压状态下，生育组左侧、右侧及双侧平均sICA均大于未生育组（P均<0.05），两组间ICT及cICA差异均无统计学意义（P均>0.05）；自然分娩亚组与剖宫产亚组ICT、sICA及cICA差异均无统计学意义（P均>0.05）。结论 MRI可准确评估女性髂尾肌形态和功能改变。 |

| Objective To observe the value of MRI in evaluation on the morphology and function of iliococcygeal muscles in fertile and nulliparous women. Methods Totally 50 healthy fertile women (fertile group, further divided into cesarean section subgroup and spontaneous delivery subgroup according to the mode of delivery) and 17 nulliparous healthy women (nulliparous group) underwent MR scanning in both natural and increased abdominal pressure state. Iliococcygeus thickness (ICT), coronal iliococcygeal angle (cICA) and sagittal iliococcygeal angle (sICA) of different states were measured and compared between the groups. Results In the natural state, the right and bilateral average sICA in the fertile group were larger than those in nulliparous group (both P<0.05), while no statistical difference of ICT, right, left and bilateral average cICA and left sICA were found between two groups (all P>0.05); the bilateral average sICA in spontaneous delivery subgroup was larger than that in cesarean section subgroup (P<0.05). In increased abdominal pressure state, left, right sICA and bilateral average sICA in fertile group were larger than those in nulliparous group (all P<0.05), while there was no statistical difference of ICT and cICA between two groups (all P>0.05); no statistical difference of ICT, cICA nor sICA was found between spontaneous delivery subgroup and cesarean section subgroup (all P>0.05). Conclusion MRI can accurately evaluate morphological and functional changes of iliococcygeal muscle in females. |
