Tracer-kinetic model-driven motion correction is an attractive solution for DCE-MRI, but previous studies only use the extended Tofts model. We propose a generalisation based on a 4-parameter 2-compartment tracer-kinetic model, and evaluate it in simulated and patient kidney data. Results show a significantly improved alignment of the data and removal of the motion-induced parameter error at a wide range of noise levels. With improvement in calculation time this is viable method for motion correction in arbitrary DCE-MRI data.
