Experimental Study on Evaluation of Blood Supply Level and Embolization Ratio of Liver Cancer Based on I-Flow Software.

Abstract:

OBJECTIVE:To confirm the feasibility and accuracy of the method for evaluating blood supply and embolization rate of liver cancer based on I-flow software through animal experiments and clinical study. METHODS:Rabbits underwent selective angiography under different perfusion conditions in the same kidney. The blood supply level was evaluated by I-flow software method. The results were analyzed for coefficient of variation. Thirty patients with liver cancer who underwent selective hepatic artery embolization were enrolled. The mathematical methods and 3 diagnostic specialists were used to evaluate the preoperative blood supply level and embolization rate. The results were recorded and the results were tested for consistency. RESULTS:Animal experiments confirmed that the blood supply level analysis method designed by the research team was consistent under different contrast conditions (including total contrast agent, contrast medium perfusion rate, and limiting pressure) (coefficient of variation: 8.55%). The mathematical calculation results of preoperative blood supply level and embolization ratio of liver cancer are consistent with the average value of visual judgment results of diagnostic experts. (Preoperative blood supply level: concordance coefficient = 0.284, P = 0.003; embolization ratio: concordance coefficient = 0.218, P = 0.011). CONCLUSION:Based on I-flow software, the mathematical calculation method designed by this research group can effectively estimate the preoperative blood supply level of liver cancer and the embolization rate of single vascular embolization treatment, which can provide reliable data support for embolization treatment of liver cancer.
