This study investigated potential effects of gadolinium contrast agent on the IVIM derived parameters such as Dfast (blood microcirculation), Dslow (pure extravascular water diffusion), f (perfusion fraction) and the commonly used DWI-derived ADC of abdominal organs. The result shows that gadolinium administration does not make statistically significant differences in Dslow, Dfast, f or ADC of the liver, spleen, or pancreas. In the kidney, however, ADC values are significantly lower with post-contrast than pre-contrast.
