目的探讨双源螺旋CT三维重建技术在肝癌介入治疗中的应用价值。方法对37例肝癌患者进行双源螺旋CT扫描诊断后,在后处理工作站进行容积再现(VR)、最大密度投影(MIP)血管重建。结果肝动脉期VR图像和MIP多平面重建图像均能清晰显示腹腔干、脾动脉、肝总动脉左右动脉及其2～3级分支,还能清晰显示l～6级门静脉血管结构及1～3级肝静脉血管分支,具有较强的空间立体感。结论双源螺旋CT门静脉三维重建成像是一种快捷而有效的无创性血管造影技术,有助于临床治疗方案的合理选择及疗效随访。
Objective To investigate the value of dual-source helical CT three-dimensional reconstruction in the interventional treatment of liver cancer. Methods 37 patients with hepatocellular carcinoma were diagnosed by dual-source helical CT scan, and volume rendering (VR) and maximum density projection (MIP) revascularization were performed in the post-processing workstation. Results Both hepatic arterial phase VR images and MIP multiplanar reconstruction images clearly showed celiac trunk, splenic artery, left and right hepatic artery and their 2 nd and 3 branches, as well as clear visualization of grade 1 ~ 6 portal vein structures and 1 ~ 3 Grade hepatic vein branch, with a strong sense of spatial three-dimensional. Conclusion Three-dimensional reconstruction of portal vein by dual-source spiral CT is a quick and effective noninvasive angiography technique, which is helpful for the rational selection and follow-up of clinical treatment.
