Image navigator based free-breathing whole heart 3D T2prep-based T2 mapping achieved similar accuracy to a conventional 2D-BH T2prep-based mapping approach, and can be performed within less than 5 minutes. With this approach the limitations of conventional 2D T2 mapping (low resolution, mis-registration and diaphragmatic motion between BH) as well as 3D T2 mapping (unpredictable scan time because of navigator gating) have been overcome. These promising results warrant further investigation in patients with myocardial pathologies.
