The purpose of this prospective study was to quantitatively measure the hepatocyte-specific uptake of Gd-EOB-DTPA using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and compare it with histopathological grading of fibrosis. The biopsy scores were grouped into no/mild fibrosis (F0-2, n=27) and advanced fibrosis (F3-4, n=11). Applying a new quantification procedure for calculation of the hepatocyte specific contrast uptake, this study can confirm that impaired hepatobiliary function severely influences the hepatocyte-specific uptake of Gd-EOB-DTPA and shows promising results for a non-invasive approach to separate mild liver fibrosis from advanced, something pure SI-based contrast ratios may fail to distinguish.
