Gated MRI reconstructions with shortened scan times (10, 7, 5, 3 and 1 min) and different levels of k-space undersampling (a). Sagittal slice of fluorine-18 fludeoxyglucose uptake in the heart and in a lesion, as a result of an ungated reconstruction using all the positron emission tomography (PET) data (b), gated reconstruction using 40% of the PET data (c) and gated reconstruction using post-reconstruction registration (d).
