Dynamic contrast-enhanced magnetic resonance imaging parameters of spleen corresponding to the stage of liver fibrosis.

Notes: TTP  =  time to peak, PEI  =  positive enhancement integral, MSI  =  maximum slope of increase, and MSD  =  maximum slope of decrease. S0, S1, S2, S3 and S4 represent liver fibrosis stage 0, 1, 2, 3 and 4, respectively; a, b, c and d represent different from S0, from S1, from S2, and from S3, respectively (all P<0.05). * denotes the significance after Bonferroni correction.
