摘要
目的:探讨利用CTA原始数据集构建在体女性盆腔静脉血管网数字化三维模型的方法及意义。方法:基于双源CTA技术,获取1例宫颈癌患者的Dicom 3.0原始二维断层图像数据集。利用Mimics 10.01软件分别对骨盆、盆腔动脉血管网以及盆腔静脉血管网进行三维重建并配准融合。结果:构建的盆腔静脉血管网数字化三维模型可以清楚地显示下腔静脉、髂总静脉、髂外静脉、髂内静脉及其初级属支,以及双侧卵巢静脉等。与重建的骨盆、盆腔动脉血管网配准融合后,各支静脉血管的解剖走形及引流区域变得更加清晰明确。结论:基于CTA的计算机三维重建技术是一种研究女性盆腔静脉血管网的好方法,具有较大的运用价值。
Objective： To investigate the construction and significance of digital three-dimensional model of in vivo female pelvic venous vascular network based on computed tomography angiography. Methods： The original Dicom 3.0 datasets were obtained from one cervical cancer patient by CTA. Then the pelvis, pelvic artery vascular network and pelvic venous vascular network were reconstructed b- y inputting the datasets into Mimics 10.01 software. Results：The digital three-dimensional model of pelvic venous vascular network can clearly show the inferior vena cava, the common iliac vein, the external iliac vein, the internal iliac vein and its primary branches, bilater- al ovarian vein, et al. Combined with the view of venous vascular network with pelvis and pelvic arterial vascular network, the anatomic structure and drainage region of pelvic veins are much more clearer. Conclusion：The three-dimensional construction technology is a good method to investigate the female venous vascular network, which may have great potential in clinical practice.
