A free-breathing non-rigid motion
corrected high-resolution 3D whole heart grey-blood PSIR slow infusion imaging
protocol with water/fat Dixon encoding at 1.5 mm3
isotropic resolution was proposed for improved scar visualization.
3D
grey-blood PSIR image and fat volume in coronal and short axis views for two
representative cases with scar. Excellent scar to myocardium SNR can be observed
in both cases.
Comparison
between the 2D and 3D grey-blood PSIR images for 3
patients. Corresponding slice positions of the 2D short-axis images were
reformatted for the 3D grey-blood PSIR images. Image quality is comparable
across the slices for all the cases with a good depiction of scar observed
across the whole 3D volume compared to the 2D acquisition.
