Objective: To analyze the value of C-arm CT and angiography in the diagnosis of liver cancer and the value of interventional therapy. Methods: Sixty-three patients with hepatocellular carcinoma confirmed by our hospital were treated with interventional therapy. Among them, 66 patients were C-arm CT-assisted interventional therapy group, CT group, 70 patients in DSA-assisted intervention group and DSA group. The Methods for the diagnosis of tumor blood supply and the effect of adjuvant intervention were compared. SPSS 17.0 statistical software was used to build the database and complete the data analysis. Results: In the study, CT images of the patients with both CT and DSA imaging results suggest that the location of the main lesion consistent with that of DSA, the number and size were basically matching. In the CT group, 61 patients(92.42%) had arterial blood supply, 5(7.58%) and moderate blood supply. The DSA group indicated that 60 cases(85.71%) showed arterial blood supply, 8 cases(11.43%) and 2 cases(2.86%) were moderate and less blood supply. There was no statistical difference between the two groups. At the same time, the two Methods were found to have direct blood supply of portal vein cases; CT group showed 7 cases(10.61%) cases of portal vein blood supply cases, DSA group suggested 6 cases(8.57%) portal vein blood supply cases with no differences between the two groups. The effective rate of CT group was significantly higher than that of DSA group(17.14%), P<0.05; In addition, the effective rate of CT group was 59.09%, the total effective rate was 93.94% in the study which was(effective + effective)/total number of cases×100%; DSA group effective rate was 71.43% The total effective rate was 88.57%, but the difference between the effective and the total effective rate was not statistically significant between the two groups. Conclusion: C-arm CT-assisted diagnosis and treatment of liver cancer can provide more detailed real-time image information, which has ertain contribution in improving the effective rate, thus it is worthy of clinical promotion.
