摘要
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 spiral CT three dimensional reconstruction in the interventional treatment.Methods Totally 37 patients with liver cancer for dual source spiral CT scan diagnosis,in the post-processing workstation for volume rendering（VR）,maximum intensity projection（MIP） revascularization.Results The hepatic arterial phase MIP,VR images and multiplanar reconstruction images could clearly show the celiac trunk,splenic artery,hepatic artery about 2~3 artery and its branches,but also clearly show the 1~6 Class doors and 1 vein structure three branches of hepatic veins,with a strong spatial dimension.Conclusions The dual source spiral CT three dimensional reconstruction of portal vein imaging is a fast and effective non-invasive vascular imaging techniques,useful in clinical treatment choice and efficacy of a reasonable follow-up.
