We present a method to reconstruct 4D images from MR PET list mode data with motion correction. We estimate a high resolution motion vector field from a short time MR acquisition and extend this frame using data driven PET techniques. Finally we reconstruct a motion corrected fully 4D image using time activity curves. We present results on clinical data.
