【摘要】：目的:建立各期宫颈癌患者盆腔动脉血管网的三维可视化数字模型并分析其特点。方法:应用64排螺旋CT血管成像技术(CTA),获得宫颈癌患者CT薄层扫描数据,在腹部医学三维可视化系统进行图像分割及三维重建,然后将重建模型导入Free Form Modeling System平台进行平滑、上色、透明化、旋转等操作,获得盆腔动脉血管网三维可视化模型。结果:成功重建出宫颈癌患者盆腔动脉血管网的三维可视化数字模型,可以清楚显示腹主动脉、髂内及髂外动脉、子宫动脉、子宫动脉上行支等主要及细小血管分支,并与骨盆配准后,可清楚了解各血管走行及空间位置,并且随着肿瘤期别的提高,患者盆腔动脉血管网的密度、分支情况等均呈增加趋势。结论:基于CTA数据,应用腹部医学三维可视化系统软件,可以成功重建出活体宫颈癌患者盆腔动脉血管网的三维可视化数字模型,并且各期宫颈癌患者动脉血管网有其不同特点,了解其不同特点对我们的手术或介入治疗有一定的指导意义。
[Abstract]:Objective: to establish a three-dimensional visualization digital model of pelvic arterial network in patients with cervical cancer and analyze its characteristics. Methods: the CT thin slice scanning data of cervical cancer patients were obtained by using 64-slice spiral CT angiography technique. The images were segmented and reconstructed in the three-dimensional visualization system of abdominal medicine. Then the reconstruction model was imported into the Free Form Modeling System platform for smoothing. Three-dimensional visualization model of pelvic artery network was obtained by coloring, transparency, rotation and so on. Results: the 3D visual digital model of pelvic artery network was successfully reconstructed. The main and small branches of abdominal aorta, internal and external iliac artery, uterine artery, ascending branch of uterine artery, and so on could be clearly displayed. After registration with the pelvis, we can clearly understand the route and space position of each vessel, and with the increase of tumor stage, the density and branch of the pelvic artery vascular network in the patients showed an increasing trend. Conclusion: based on the CTA data, the 3D visualization digital model of pelvic artery network in patients with cervical cancer can be successfully reconstructed by using the three-dimensional visualization system software of abdominal medicine. There are different characteristics of arterial vascular network in patients with cervical cancer in different stages. Understanding the different characteristics of arterial vascular network has certain guiding significance for our operation or interventional therapy.
