Multi-slice CT angiography in the guidance of interventional chemotherapy and embolization of liver tumr

Objective To discuss the value of multi-slice CT angiography in interventional chemotherapy treatment of liver tumor. Methods A total of 32 patients with liver tumor underwent 16 slice CT angiography, and the results were compared with DSA during interventional chemotherapy and embolization. Results Variation arteries were detecded by MSCTA in 10 cases and supplement arteries of tumor in 30 cases with the accurate ratio of 100% and 93.75%, respectively while tumor stain (24 cases), abnormal tumor vessels (20 cases), embolism in portal vein (7 cases), and A-V shunt (4 cases) were found with MSCTA and proverd with DSA. Conclusion MSCTA shows variation artery and supplement artery of tumor outside liver accurately and provides the information of embolism in portal vein before interventional therapy. It is important for the guidance of interventional therapy of liver tumor.
