Histogram analysis of whole-liver ADC maps was applied for patients with liver fibrosis to assess its diagnostic value and correlation with fibrosis stages achieved from liver biopsy. Our study shows that the mean and the 75th percentile ADC were significantly lower with the increasing grade of liver fibrosis. The median, standard deviation (SD), 5th, 10th, 25th, 90th and 95th percentiles also showed statistical differences among pathological fibrosis grades. In conclusion, histogram analysis of whole-liver ADC maps has a potential value for quantifying liver fibrosis grades.
