Abstract: Objective To investigate the computed tomography （CT） scan in evaluating the therapeutic effect of transcatheter arterial chemoembolization（TACE） in patients with primary liver cancer（PLC）. Methods The clinical data of 92 patients with PLC treated by TACE in our hospital between October 2015 and December 2016 were retrospectively collected. The CT scan and enhanced scan were performed before and after TACE. The density,enhancement patterns,border and size of the intrahepatic lesions before and after TACE were compared. Results There were 22 cases （30.1%） of type I,40 cases （54.7%） of type II,8 cases （10.9%） of type III and 3 cases（4.1%） of type IV lipiodol deposition in 73 patients with intrahepatic huge mass,and there were 14 cases（73.6%） of type I,4 cases（21%） of type II and 1 cases （5.2%） of type III lipiodol deposition in 19 patients with intrahepatic nodular lesions. The total effective rates in the two groups after TACE treatment were 95.5% （69/73） and 94.7% （18/19,P>0.05）. Conclusion CT examination is effective in evaluating the clinical efficacy of TACE treatment in patients with PLC, which provides accurate imaging information for further clinical strategy.
