【摘要】：目的:研究正常未育青年女性静息状态阴道三维精细解剖结构。方法:收集2013年1月至2016年10月于南方医院妇科就诊患者的MRI影像数据及一般资料。选择满足入选要求的45例青年未育女性静息状态下MRI数据集,利用Mimics 10.01软件进行三维重建,联合UG软件对阴道及其与尿道之间的精细解剖参数进行三维测量和分析。结果:所有数据可构建阴道和尿道三维模型。阴道相关精细解剖参数如下:近、中、远端尿道阴道间隙依次为:5.99±1.95 mm、3.06±1.62 mm、1.09±1.43 mm。近端阴道前壁宽度34.09±6.83 mm,远端阴道前壁宽度29.69±5.60mm,阴道前壁中线长度61.02±10.12 mm。中段阴道轴位二维形态有H型和浅凹型两种,其中H型占比91.11%。结论:计算机三维重建技术能够直观再现人体阴道三维解剖形态,提供阴道精细解剖的三维研究的平台,通过多项径线的测量,反映正常状态下阴道及其周围支持结构功能的情况。
[Abstract]:Objective: to study the three-dimensional fine anatomical structure of the vagina in the resting state of normal unbred young women. Methods: from January 2013 to October 2016, MRI imaging data and general data of gynecological patients in South China Hospital were collected. The MRI data sets of 45 young unbred women were selected and reconstructed by Mimics 10.01 software. The fine anatomical parameters between vagina and urethra were measured and analyzed with UG software. Results: all the data can be used to construct three-dimensional models of vagina and urethra. The detailed anatomical parameters of vagina were as follows: in the proximal, middle and distal urethra, the vaginal space was: 5.99 卤1.95mm / 3.06 卤1.62mm / 1.09 卤1.43mm. The width of anterior wall was 34.09 卤6.83 mm, the width of distal anterior wall was 29.69 卤5.60 mm, and the length of midline of anterior wall of vagina was 61.02 卤10.12 mm. There are two types of H-type and shallow concave type in the axial position of the midsection of vagina, among which H-type accounts for 91.11%. Conclusion: the computer 3D reconstruction technique can visualize the three-dimensional anatomy of human vagina and provide a platform for the study of the fine anatomy of the vagina. Reflects the normal state of the vagina and its surrounding support structure function.
