Abstract: Objective  To investigate the application value of spectral CT in the differential diagnosis of  benign and malignant portal vein thrombosis. Methods  The spectral CT images of 58 cases of hepatic carcinoma complicated with portal venous emboli were retrospectively analyzed. Single energy CT value (40～140Kev) of primary hepatic tumors and portal venous emboli were calculated. The datasets were divided into portal tumor thrombus group (n=32) and portal vein thrombosis group (n=26) and then compared.  Results  Single energy CT value in the primary hepatic carcinoma and portal tumor thrombus group was similar (P>0.05), but there was significant difference between primary hepatic carcinoma and portal vein thrombosis (P<0.05).  Conclusion  The spectral CT as a new and non-invasive method can improve the diagnostic efficiency of portal venous emboli.
