Visual comparison between 2D LGE and 3D water LGE images, acquired every heartbeat for 2 representative patients, showing short-axis (top row) and horizontal long-axis (bottom row) views. In Patient 6, small areas of LGE can be observed with both the 2D LGE and 3D LGE water images (green arrows), with an increased scar-to-blood contrast ratio observable in the 3D water images (blue arrows). A similar depiction of the myocardial wall with no LGE findings can be observed for both the conventional 2D and proposed 3D approaches in Patient 8
