Image reconstruction with deformable motion correction for dynamic contrast-enhanced (DCE) MRI can counteract artifacts in dynamic images and estimated perfusion maps. In this study, we present the results of applying a reconstruction method with deformable motion correction to 54 DCE-MRI examinations of 31 patients. Deformable motion correction is found to compensate for up to 15 mm of residual motion after rigid-body motion correction. Motion-correction also reduces liver-wide bias caused by motion-distorted input functions and removes localized artifacts at liver edges. Finally, for several cases, motion-correction makes lesion edges sharper in reconstructed images.
