FIG. 9.

a: Comparison between the wideband 2D LGE sequence the modified wideband 3D LGE sequence at the same slice locations of the myocardium from two ICD patients who were scheduled for VT ablation. The 3D images appear less noisy and provide better coverage of the myocardium and scar regions. The ICD is located at the upper-left of the image. b,c: Four-chamber HLA images created from the 2D (B) and 3D (C) LGE images. In (B), the 2D LGE images were stacked to produce the volume, and reformatted to the HLA view. The large slice thickness and slice mis-registration is evident in the 2D reformatted image (B), while the 3D volume and higher slice resolution in (C) produces a better HLA image. d–f: A similar comparison on a different ICD patient. Note the slices in the 2D scans were 100% thicker than the 3D scans.
