Objective : To explore the quantitative method for the treatment of liver cancer by ultrasonic interventional injection of absolute alcohol. Methods: 86 cases of 16 recurrent hepatocellular carcinoma nodules were treated with ultrasound-guided absolute alcohol injection (PEI). The correlation coefficient between the alcohol injection volume and the maximum diameter of the diffusion range was calculated. 2 The regression equation of the size of the tumor and the alcohol injection volume. . Results: There was a very significant positive correlation between the amount of alcohol injection and the diffusion range (r=0.884, P=0. 0 0 0). The regression equation for tumor nodule size and alcohol injection volume was: when the tumor diameter was ≤ 5 cm Y = 2.885 X. When the tumor diameter is greater than 5 cm, the regression equation is Y = 1.80 5 X (where X is the maximum diameter of the tumor, and Y is the alcohol injection volume). Conclusion: The regression equation of tumor nodule diameter and alcohol injection volume derived from the correlation between alcohol injection volume and diffusion range was clinically applied and followed up for observation. It has a positive effect and can be used as a calculation method for alcohol injection volume during PEI.
