Correcting Patient Movement in Dynamic Contrast Enhanced MRI

Andrew Melbourne¹

This work is a review of techniques for retrospective automatic image registration techniques in dynamic contrast enhanced (DCE) MRI. Due to the length of time required to obtain a DCE MRI series image registration techniques are used to correct subject movement between imaging volumes prior to physiological model-fitting to extract features of the enhancement pattern. These techniques are often modified for the DCE setting so that they separate motion artefacts from contrast enhancement. Due to the proliferation of techniques a review is worthwhile so that knowledge of the technical details of image registration can be made more widely available.
