Figure 1

Comparison between (left) 2-dimensional late gadolinium enhancement (LGE) imaging (typical voxel size 2.9 × 1.9 × 6 mm) and (right) corresponding high-resolution 3D LGE imaging (voxel size 1.3 × 1.3 × 1.3 mm) in a patient with surgically corrected Tetralogy of Fallot. White arrows indicate region of surgical infundibulotomy scar with improved characterization of the thin surgical scar being apparent using 3D LGE imaging. Yellow arrows indicate inferior RV insertion site fibrosis.
