Abstract:
Objective To investigate the differences in GD-EOB-DTPA multi-modality MR images be-tween well-differentiated hepatocellular carcinoma(WHCC)and non well-differentiated HCC.Methods The clin-ical and MR images of 57 patients with pathologically proved HCC were retrospectively collected. All patients un-derwent abdominal enhancement MRI,including T1 weighted and T2 weighted imaging(T1WI and T2WI),diffu-sion weighted imaging(DWI),the apparent diffusion coefficient(ADC)map,and gadoxetic acid-enhanced multi-phase sequences. The patients were classified into well-differentiated HCC(WHCC)group and non-WHCC group which combined moderate HCC and poor differentiated HCC according to their histopathological differentiation.Dif-ferences of T1WI,T2WI,DWI,ADC map,the types of HCC on hepatobiliary phase(HBP)images,and enhance-ment patterns on dynamic images were compared. The chi-square test or Fisher exact was used for comparing the imaging signal differences between WHCC and non-WHCC. Multiple logistic regression analysis was performed to identify the independent predictors of WHCC. Results T1WI signal intensities,HBP signal types,enhancement patterns and ADC maps showed statistical significance between WHCC and non-WHCC(P<0.05).But,multiple logistic regression analysis showed that signal intensities on T1WI were independent risk factors for WHCC(P =0.001). In addition,hyperintense on T1WI showed higher statistical significance compared with isointense or hy-pointense on T1WI(P = 0.002). Conclusions Multi-modality of GD-EOB-DTPA MRI is useful for assessing WHCC. The signal intensities on T1WI are independent risk factors for evaluating WHCC. Moreover,WHCC are more likely in hyperintense T1WI signal intensity.
