ObjectiveTo explore the relationship between the signal intensity on hepatobiliary phase of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI and the degree of differentiation of hepatocelluar carcinoma (HCC). MethodsForty-eight cases of HCC with Gd-EOB-DTPA-enhanced MRI images in our hospital were retrospectively included. The signal to noise ratio (SNR), contrast ratio (CR), enhancement ratio of signal to noise ratio (%EnhancementSNR), enhancement ratio of the contrast ratio (%EnhancementCR), enhancement ratio (ER), and relative enhancement ratio (RER) were calculated, respectively. Then comparisons of these signal values among different differentiations of HCC were performed. ResultsAmong the 48 cases of HCC, there were 6 cases of well differentiated, 24 cases of moderately differentiated, and 18 cases of poorly differentiated. There were 37 cases of Child-Turcotte-Pugh (CTP)A classification and 11 cases of B classification, respectively. Neither in all cases nor in cases of CTP A classification, there was no statistically significant difference in SNR, CR, %EnhancementSNR, %EnhancementCR, ER, and RER among cases of different differentiation (P > 0.05). ConclusionThe signal intensity on hepatobiliary phase images of Gd-EOB-DTPA-enhanced MRI has limited value in predicting the degree of differentiation of HCC.
