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.
