Most MRI contrast agents distributes extracellular only. If the extracellular water signal is suppressed by diffusion weighting the short ranged T1-relaxation effect of a the contrast agent will be solely through water exchange through the cell membrane. In this paper we describe the implementation of a dynamic contrast enhanced diffusion weighted acquisition facilitating the study of diffusion weighting on the relaxivity of contrast agents. This is all done within a Split Dynamic framework allowing for this study to be performed without sacrificing assessment of the established pharmacokinetic parameters.
