[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.
