[Abstract] Objective To investigate the relationship between lobar based signal intensity parameters and Albumin - Bilirubin (ALBI) grade in patients with chronic hepatitis B-related liver cirrhosis on gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (Gd-EOB-DTPA) enhanced MRI.Materials and Methods: Gd-EOB-DTPA enhanced MRI images of 62 patients with normal liver (n=15), ALBI grade 1 (n=23), ALBI grade 2 (n=18), and ALBI grade 3 (n=6) with chronic hepatitis B associated cirrhosis were analyzed. Liver parenchyma relative enhancement (LRE) and liver-to-muscle ratio (LMR) of right lobe, left medial lobe, left lateral lobe and caudate lobe were calculated, and compared between normal group and different ALBI grading groups. The relationship between LRE, LMR and ALBI grading of liver lobes in patients with chronic hepatitis B-related cirrhosis was quantitatively analyzed, and the accuracy of ALBI grade 1 and ALBI grade 2-3 were evaluated by ROC curve.Results The LRE and LMR values of each liver lobe were significantly different between the normal group and different ALBI grading groups (P<0.05). The pairings of each group showed that there was no significant difference in LRE value of each liver lobe between ALBI 2 and ALBI 3 groups (P>0.05), and there was a significant difference in LMR value of each liver lobe between any two groups (P<0.001). The LRE and LMR of each lobe of liver in patients with chronic hepatitis B-related liver cirrhosis were negatively correlated with ALBI grade (P<0.001). LRE in the right lobe of the liver had the highest accuracy in distinguishing ALBI grade 1 from ALBI grade 2-3, and the area under the receiver operating characteristic curve is 0.913.Conclusions There is a correlation between LRE and LMR based on liver lobe and ALBI grade of liver function in patients with chronic hepatitis B related cirrhosis in Gd-EOB-DTPA enhanced MRI. LRE and LMR are expected to be imaging methods to evaluate liver lobe function.
