Studies have sought to use changes in hepatic apparent diffusion coefficient (ADC) as an imaging biomarker for the assessment of the degree of fibrosis. In this study, the effect of a high-caloric food intake on ADC was investigated. The result showed that ADC(b = 0,1000s/mm2) and ADC(b = 200,1000s/mm2) increased following a 1090kcal meal ingestion.
