Abstract: This study investigated the characteristics and significance of spectral CT parameters of residual lesions and early new lesions after intervention for advanced liver cancer. 100 patients with primary liver cancer (liver cancer group) were selected, and 50 patients with hepatic hemangioma were selected as the control group (liver hemangioma group), and the patients with primary liver cancer were treated with percutaneous hepatic arterial chemoembolization (TACE). The differences of energy spectrum CT parameters between the two groups before operation were analyzed, the differences of energy spectrum CT parameters of residual and recurrent lesions and no residual or recurrent lesions in liver cancer group were analyzed. The venous standardized iodine concentration (VNIC), arterial standardized iodine concentration (ANIC), standardized iodine concentration ratio (ICratio), arterial curve slope and venous curve slope in liver cancer group were significantly higher than those in patients with hepatic hemangioma (P<0.05). VNIC, ANIC, ICratio, arterial phase curve slope and venous phase curve slope of recurrent lesions were significantly higher than those of residual lesions, no residual or recurrent lesions (P<0.05). There are significant differences in the energy spectrum CT parameters between hepatic hemangioma and liver cancer, and it has a certain application value in the diagnosis of postoperative recurrence of primary liver cancer patients.
