Correlation analysis between biliary R1 at early stage and biochemical parameters at 4 h of NMP. Correlation analysis was conducted between biliary R1 at 1 h after Gd-EOB-DTPA injection (60′) and conventional biochemical indexes at 4 h after NMP (ALT, perfusate lactate and biliary pH). (A) ALT value at 4 h after NMP had a strong correlation with values of biliary R1 (60′) (Spearman; r, − 0.854; p < 0.001). (B) Lactate value at 4 h after NMP had no significant correlation with values of biliary R1 (60′) (Spearman; r, − 0.476; p = 0.054). (C) There is a moderate between values of R1 (60′) and Biliary pH at 4 h after NMP (Spearman; r, 0.531; p = 0.028).
