Abstract: The purpose of this study was to explore the comparative study of contrast-enhanced CT and contrast-enhanced magnetic resonance imaging (CE-MRI) in the assessment of the size and blood supply of hepatocellular carcinoma (HCC), 112 lesions of 102 patients with HCC were selected, the contrast-enhanced CT and CE-MRI images were compared, chi square test was used to test the differences in sensitivity and specificity between the groups, and Kappa was used to test the consistency of the two methods.The HCC diagnostic sensitivity, specificity and accuracy of enhanced CT and CE-MRI were 90.29% and 94.17%, 88.89% and 88.89%, 90.18% and 93.75% respectively, and the difference was not statistically significant (P>0.05). The lesions measured by contrast-enhanced CT and CE-MRI was not statistically significant (P>0.05). In female and male patients, there was no significant difference in the volume of lesions measured by contrast-enhanced CT and CE-MRI (P>0.05). Among 112 lesions, 99 lesions with rich blood supply and 3 lesions with poor blood supply were determined by contrast-enhanced CT and CE-MRI. The consistency of Kappa value of blood supply was determined by contrast-enhanced CT and CE-MRI was 0.668, P< 0.05. There was no significant difference in blood supply between male and female patients by contrast-enhanced CT and CE-MRI (P>0.05). Contrast-enhanced CT and CE-MRI showed good consistency in the size and blood supply assessment of HCC.
