Abstract：Objective To evaluate the synergistic effect of dual-energy computed tomography angiography (CTA) and digital substraction angiography (DSA) on transcatheter chemoembolization of hepatocellular carcinoma.Methods Transcatheter chemoembolization was performed in 98 patients with hepatocellular carcinoma from Aug. 2013 to Aug. 2014. The patients were divided into two groups randomly. Fifty patients underwent dual-energy CTA before transcatheter chemoembolization were regarded as group 1 with post-procession of VR, MIP and MPR; meanwhile other 48 patients were regarded as group 2 without CTA. The number of tumor-feeding vessels and used catheters, dose of contrast medium, amount of DSA series, time of exposure and operation, dose area product, and degree of transcatheter chemoembolization were compared.Results All tumor-feeding vessels in group 1 were observed by dual-energy CTA clearly with exact display of the origin, course, and diameter of the vessels. The number of tumor-feeding vessels in group 1 was 2.72±0.89,more than that in group 2(1.88±0.74), exhibiting a statistical difference between two groups (P<0.01). The number of catheters used, dose of contrast medium, amount of DSA series, time of exposure and operation, and dose area product in group 1 were less than those in group 2, also exhibiting the statistical difference (all P values<0.05).Conclusions Combination of dual-energy CTA and DSA is reasonable and practicable, which has synergistic effect on interventional therapy for hepatocellular carcinoma.
