We evaluated whether DKI analysis as an indicator of liver function can replace laboratory tests. The mean kurtosis value was found to correlate with the Child–Pugh score and the ICG score. However, the correlation between the mean kurtosis valueand the ALBI score was the poorest among these. ADC values correlated with only the ICG score. The mean kurtosis value can be one of predictors for liver function owing to its correlation with typical indicators of liver function by serum data although this method, which shows liver function using DKI alone, cannot completely substitute the laboratory tests.
