Abstract：Objective: To analyze the application value of dual-energy CT imaging in the evaluation of postoperative effect of hepatic arterial chemoembolization for primary hepatocellular carcinoma (HCC). Methods: Imaging data of 40 patients with HCC treated by hepatic artery embolization chemotherapy admitted from January 2019 to January 2020 were retrospectively analyzed, with conventional CT images and CT dual-energy iodograms obtained by dual-energy CT scan examination 4 weeks after surgery. Using the results of DSA as the gold standard, the diagnostic efficacy of two CT examination methods for residual lesions after liver cancer surgery was compared. the iodine concentration values (IC) and standard iodine concentration values (NIC) of CT dual-energy iodograms of patients' postoperative residual lesions and normal liver tissue were measured to determine their residual lesion activity. Results: Using DSA findings as the gold standard, the sensitivity, specificity and accuracy of dual-energy CT in detecting residual lesions after HCC were higher than those of conventional CT, and the difference was statistically significant (P<0.05). The ROC curve showed that the AUC of dual-energy CT for the diagnosis of residual lesions after HCC was 0.861, which was greater than that of conventional CT at 0.658. The IC and NIC values of residual active lesions after HCC were higher than those of normal liver tissue, and the difference was statistically significant (P<0.05). Conclusion: Dual-energy CT imaging has significant clinical value in the detection of residual lesions after hepatic arterial chemoembolization for liver cancer, and its IC value and NIC values have a certain potential in judging the degree of lesion activity.
