This study was to evaluate CT vein image segmentation and three-dimensional imaging in the anatomical structure of gastrocolic venous trunk before operation for colon cancer.
CT scanning images by Philips Brilliance CT 256CT scanner. Vein position was segmented and calculated by grey value through algorithm flow. Intensity measurement of selected image area by a calculate through noise cancellation and missing pixel filling, based on numerical morphology.
The direction of the right colonic vein could be clearly displayed in all 96 patients by morphological filtering technique. Among these patients, there were 78 patients with gastrocolic vein trunk, with an occurrence rate of 81.25%. According to the classification of GVT, there were 36 cases of type A (46.2%), 22 cases of type B (28.2%), 12 cases of type C (15.4%) and 6 cases of type D (7.7%).
CT vein image segmentation and three-dimensional imaging can effectively evaluate the anatomical variation of gastrocolic vein trunk before operation, which is helpful for operators to correctly understand its anatomical structure and choose a reasonable anatomical approach.
本研究旨在评估结肠癌手术前胃结肠静脉干解剖结构的CT静脉图像分割及三维成像。
采用飞利浦Brilliance CT 256CT扫描仪进行CT扫描成像。通过算法流程利用灰度值对静脉位置进行分割和计算。基于数字形态学，通过噪声消除和缺失像素填充对选定图像区域进行强度测量。
采用形态学滤波技术可在全部96例患者中清晰显示右结肠静脉走行。其中，胃结肠静脉干78例，发生率为81.25%。根据胃结肠静脉干分类，A型36例（46.2%），B型22例（28.2%），C型12例（15.4%），D型6例（7.7%）。
CT静脉图像分割及三维成像可有效评估手术前胃结肠静脉干的解剖变异，有助于术者正确了解其解剖结构并选择合理的解剖入路。
