本研究的目的是通过计算机断层扫描可视化女性骨盆的手术解剖结构，并研究解剖学教育、放射学诊断和手术模拟的参数组成。我们对保持在精确手术解剖位置的新鲜女性尸体进行手术解剖，并使用实验细细胞检测器多层计算机断层扫描（FDCT）检查解剖结构，层厚为0.3125 mm。此外，我们使用Materialise的交互式医学图像控制系统（Mimics）建立了一个三维（3D）重建模型，用于精确观察手术解剖结构。我们结合三维重建模型评估了手术解剖结构的二维（2D）图像。以430具尸体连续轴向骨盆CT图像为基础，重建三维模型。在手术切除部位的CT图像上显示主韧带、子宫骶韧带、膀胱旁间隙和直肠旁间隙。在手术解剖侧，参数组成清晰区分。根据解剖侧的信息，也可以区分未解剖侧的这些成分。我们确认了在根治性子宫切除术中切除区域的参数成分。该方法使用尸体，实验FDCT和3D软件提供了良好的骨盆结构可视化。高质量的外科解剖结构图像为女性骨盆的精确外科解剖提供了新的见解。放射学信息对放射治疗计划和手术模拟具有实用价值。中国。[j] .农业学报，2014。©2013 Wiley期刊公司
The objectives of this study were to visualize the surgical anatomical structures in the female pelvis by computed tomography and to investigate the components of the parametrium for anatomical education, radiological diagnosis, and surgical simulation. We surgically dissected fresh female cadavers maintained in precise surgical anatomic positions and examined the anatomical structures using experimental fine cell detector multislice computed tomography (FDCT) with a slice thickness of 0.3125 mm. In addition, we established a three‐dimensional (3D) reconstruction model for precise observation of the surgical anatomy using Materialise's Interactive Medical Image Control System (Mimics). We evaluated two‐dimensional (2D) images of the surgical anatomical structures in combination with the 3D reconstruction model. The 3D model was reconstructed from 430 serial axial pelvic CT images of a cadaver. The cardinal ligament, uterosacral ligament, paravesical space, and pararectal space were visualized on the CT images obtained from the surgically dissected part. The parametrium components were clearly distinguished on the surgically dissected side. Based on the information from the dissected side, these components on the undissected side could be distinguished as well. We recognized the parametrium components in the area extirpated during radical hysterectomy. The approach using cadavers, experimental FDCT, and 3D software provided excellent visualization of pelvic structures. High‐quality images of surgical anatomical structures provide new insight regarding precise surgical anatomy in the female pelvis. The radiological information has practical usefulness for radiotherapeutic planning and surgical simulation. Clin. Anat. 27:503–510, 2014. © 2013 Wiley Periodicals, Inc.
