【摘要】：目的：探讨在仰卧位与俯卧位对子宫行磁共振扫描，评价子宫形态学变化。方法：2013年11月至2014年1月，征集30位年龄在20-30岁之间的女性志愿者，行磁共振扫描。分别行仰卧位与俯卧位MRI检查，，在矢状位和轴位T2WI图像上观察子宫的位置；测量子宫体长度、子宫体横断面径线、子宫矢状位宫底至腹壁和至骶尾骨的垂直距离、子宫倾度及子宫屈度；比较仰卧位与俯卧位扫描条件下，子宫形态学改变测量数据是否有统计学差异。结果：（1）我们扫描30例志愿者的子宫中，子宫前倾位有20例，其中前屈位有14例，后屈位有6例；子宫后倾位有10例，其中前屈位有8例，后屈位有2例。仰卧位与俯卧位各组数据为：子宫体平均长度分别为54.96±6.43mm、55.363±7.90mm；子宫体横断面平均长径分别为49.74±6.74mm、50.00±6.41mm，平均短径分别为43.71±5.60mm、44.19±5.70mm；子宫平均倾度分别为113.49°±41.93°、113.126°±40.59°；子宫平均屈度分别为104.61°±34.57°、108.52°±34.84°；矢状位宫底至腹壁垂直距离平均值分别为61.21±42.16mm、66.15±62.61mm；宫底至骶尾骨垂直距离平均值分别为57.63±40.05mm、62.61±44.03mm。子宫体长度、子宫倾度及子宫横轴位长短径在仰卧位与俯卧位差异无明显统计学意义(P0.05)，矢状位宫底至腹壁垂直距离、宫底至骶尾骨垂直距离和子宫屈度差异有统计学意义（P0.05）。（2）前倾位子宫在仰卧位与俯卧位各组数据为：子宫体平均长度分别为54.96±6.39mm、55.58±8.51mm；子宫横断面平均长径分别为49.98±6.15mm、50.08±5.84mm；子宫横断面平均短径分别为43.57±5.19mm、43.98±5.16mm；子宫平均倾度分别为112.59°±43.01°、112.04°±43.47°；子宫平均屈度分别为104.87°±36.31°、112.64°±38.15°；矢状位宫底至腹壁垂直距离平均值分别为54.56±45.19mm、59.48±44.22mm；矢状位宫底至骶尾骨垂直距离平均值分别为68.53±42.11mm、74.39±46.50mm。子宫体长度、子宫体横断面长短径和子宫倾斜度在仰卧位与俯卧位差异无统计学意义(P0.05)，但矢状位宫底至腹壁垂直距离、宫底至骶尾骨垂直距离和子宫屈曲度差异有统计学意义（P0.05）。（3）后倾位子宫于仰卧位与俯卧位各组数据为：子宫体平均长度分别为54.96±6.85mm、54.92±6.92mm；子宫横断面平均长径分别为49.26±7.39mm、49.84±7.78mm，子宫横断面平均短径分别为43.98±6.66mm、44.61±6.95mm；子宫平均倾度分别为115.30°±41.90°、115.29°±36.23°；子宫平均屈度分别为104.09°±32.67°、100.28°±26.94°；矢状位宫底至腹壁垂直距离平均值分别为76.68±29.52mm、83.98±31.26mm；矢状位宫底至骶尾骨垂直距离平均值分别为35.83±25.16mm、39.05±27.50mm。子宫体长度、子宫倾度、子宫屈度、子宫体横断面长短径及矢状位宫底至骶尾骨垂直距离在仰卧位与俯卧位差异没有统计学意义，但矢状位宫底至腹壁垂直距离差异有统计学意义。结论：在仰卧位与俯卧位的不同体位相同扫描条件下，子宫形态学有一些变化：前倾位子宫屈曲度、矢状位宫底至腹壁、骶尾骨垂直距离均增大，而后倾位子宫形态学变化小，仅子宫宫底至腹壁距离有增大。
[Abstract]:Objective: To investigate the magnetic resonance imaging of uterus in supine position and prone position, and to evaluate the morphological changes of uterus.
Methods: from November 2013 to January 2014, 30 female volunteers aged 20-30 years of age were recruited by magnetic resonance imaging. The supine position and the prone position MRI were performed to observe the position of the uterus on the sagittal and axial T2WI images, and the length of the uterus, the transverse section of the uterus, the sagittal base of the uterus to the abdominal wall and the sacral caudal bone were measured. The vertical distance, uterine inclination and uterine flexion were compared. There was statistical difference in morphologic changes between the supine position and prone position scan.
Results: (1) in the uterus of 30 volunteers, there were 20 cases in the uterus, including 14 cases in the anterior flexion, 6 cases in the posterior flexion, 10 in the posterior position of the uterus, 8 in the flexion and 2 in the posterior position. The data of the supine and prone positions were 54.96 + 6.43mm, 55.363 7.90mm, and the uterine body transection. The average diameter of the surface is 49.74 6.74mm and 50 6.41mm respectively, the average short diameter of the uterus is 43.71 + 5.60mm and 44.19 + 5.70mm respectively. The average uterine inclination of the uterus is 113.49 + 41.93 and 113.126 + 40.59 degrees respectively. The average utero flexion of the uterus is 104.61 [34.57] and 108.52 + 34.84 degrees respectively. The average value of the vertical distance from the sagittal to the abdominal wall is 61.21 + 42.1, respectively. 6mm, 66.15 + 62.61mm; the average vertical distance between the uterine fundus and the sacral tail was 57.63 + 40.05mm, 62.61 + 44.03mm., and the uterine inclination and the transverse axis of the uterus had no significant difference between the supine position and the prone position (P0.05). The vertical distance from the sagittal base to the abdominal wall, the vertical distance from the fundus to the sacral caudal and the utero flexion of the sacral caudal and the uterus. The difference was statistically significant (P0.05). (2) the average length of uterus in the supine and prone positions was 54.96 + 6.39mm, 55.58 + 8.51mm, and the average length of uterus was 49.98 + 6.15mm and 50.08 + 5.84mm respectively, and the average diameter of uterus was 43.57 + 5.19mm and 43.98 + 5.16mm, respectively. The average flexion of the uterus was 104.87 [36.31] and 112.64 + 38.15 degrees, respectively, and the average value of the vertical distance between the sagittal and ventral walls was 54.56 + 45.19mm and 59.48 44.22mm, respectively, and the average vertical distance between the sagittal and the sacral caudal bone was 68.53 42.11mm and 74.39 + 46.50mm. uterus, respectively. There was no significant difference between the length and the length of the uterus and the inclination of the uterus in the supine position and the prone position (P0.05), but the vertical distance from the sagittal base to the abdominal wall, the vertical distance from the fundus to the sacral caudal bone and the uterine flexion were statistically significant (P0.05). (3) the data of the supine and prone positions of the posterior uterus in the supine and prone position were the uterine body. The average length of the uterus was 54.96 6.85mm, 54.92 6.92mm, and the average length of uterus was 49.26 + 7.39mm and 49.84 + 7.78mm respectively. The average short diameter of uterus was 43.98 + 6.66mm and 44.61 + 6.95mm, and the average uterine inclination was 115.30? 41.90 and 115.29? 36.23 degrees respectively. The average utero flexion of uterus was 104.09 + 32.67 degrees, 100.28 degrees, respectively. The average value of vertical distance between the sagittal base of the uterus and the abdominal wall was 76.68 + 29.52mm, 83.98 + 31.26mm, and the average vertical distance between the sagittal base of the uterus and the sacral tail was 35.83 + 25.16mm, 39.05 + 27.50mm., the uterus, the uterus, the transverse section of the uterus and the vertical distance between the sagittal and the sacral caudal. There was no significant difference between supine position and prone position, but the vertical distance from sagittal uterus to abdominal wall was statistically significant.
Conclusion: under the condition of the same scan of the supine position and the prone position, there are some changes in the uterus morphology: the flexion of the uterus in the forward position, the sagittal base to the abdominal wall, the vertical distance of the sacral caudal bone increased, and the morphological changes of the uterus at the back tilt are small, only the distance between the uterus and the abdominal wall is increased.
