  •   Objective   Preoperative CT perfusion imaging is beneficial to the prognosis assessment of patients with liver cancer, but there are few studies on the effect of postoperative CT perfusion imaging. This study analyzed the relationship between CT perfusion imaging parameters and short-term efficacy and long-term prognosis of patients with liver cancer after CT-guided microwave ablation (MWA), so as to further explore its application value in patients with liver cancer.   Methods   A total of 150 patients with primary liver cancer admitted to Baoding First Central Hospital from January 2020 to January 2022 were selected and separated into the effective group and the ineffective group according to the modified response evaluation criteria in solid tumor (mRECIST). CT perfusion parameters between the two groups were compared after 4 weeks of MWA treatment, and the receiver operating characteristic (ROC) curve was used to evaluate the value of CT perfusion parameters in predicting the short-term efficacy; With all-cause death as the end event, Kaplan-Meier survival curve was used to evaluate the relationship between CT perfusion parameters and prognosis of patients, and log-rank test was used to compare the differences.   Results   Hepatic artery perfusion volume (HAP) in the effective group was lower than that in the ineffective group, and the portal vein perfusion volume (PVP) was higher (P < 0.001); Both HAP and PVP had certain predictive value for the short-term efficacy of patients, and their combined detection had the highest predictive efficacy, with AUC of 0.894, sensitivity and specificity of 94.64% and 65.96%, respectively; The overall survival rate of HAP low-level group and PVP high-level group was higher than that of HAP high-level group and PVP low-level group (P < 0.05).   Conclusion   CT perfusion parameters are closely related to the short-term efficacy and long-term prognosis of HCC patients after MWA. The higher the HAP and lower the PVP, the worse the therapeutic effect and prognosis.
