目的探讨多层螺旋CT血管成像在肝癌介入治疗中的临床应用价值。方法对249例肝癌患者行MSCT肝脏增强扫描,观察肿瘤的供血血管、分支、走行、毗邻和变异情况,比较多平面重建、最大密度投影、三维容积重建技术在肝癌介入治疗前后的作用。结果MPR及VR两种方法对肝脏二级血管的显示有显著差异(P<0.017),MPR、MIP在肝脏肿瘤的二级血管显示中无显著统计学差异(P>0.017),对肝脏三级血管的显示MPR、MIP有显著统计学差异,MIP与VR比较在肝脏三级血管的显示中有显著差异(P<0.017)。经肝动脉插管栓塞化疗共计112例,且均在术前行CTA检查,占肝癌患者总数的45.0%。成功插管110例,占插管总数的98.0%。结论MSCTA能准确地显示肿瘤供血动脉解剖特点,对指导肝癌的介入治疗具有重要作用。
Objective To investigate the clinical value of multislice CT angiography in the interventional treatment of liver cancer. Methods 249 cases of liver cancer patients underwent MSCT enhanced liver scan to observe the tumor blood vessels, branches, walking, adjacent and mutation, more planar reconstruction, maximum density projection, three-dimensional volume reconstruction in the intervention of liver cancer before and after the role. Results Both MPR and VR showed significant differences in the display of hepatic secondary blood vessels (P <0.017). MPR and MIP showed no significant difference in secondary blood vessels of liver tumors (P> 0.017) Vascular MPR, MIP showed statistically significant differences, MIP and VR in the comparison of the three blood vessels showed significant differences (P <0.017). Transcatheter arterial chemoembolization for a total of 112 cases, and were preoperative CTA examination, accounting for 45.0% of the total number of patients with liver cancer. 110 cases of successful intubation, accounting for 98.0% of the total number of intubation. Conclusion MSCTA can accurately display the anatomic features of the donor artery of the tumor and play an important role in guiding the interventional treatment of liver cancer.
