Examples of raw images and corresponding scar shells for a single subject. Scans 1 and 2 were performed using identical (standard) acquisition parameters, with acquisitions performed at 10 min, 20 min and 30 min post injection of gadolinium. Scan 2 was performed 2 days after Scan 1. Upper six panels show single representative slices of the 3D late gadolinium enhancement (LGE) dataset, at the level of the aortic root. The six panels below show corresponding scar shells, normalised according to blood pool z-score. Note the relatively poor reproducibility for acquisitions at 10 min, particularly Scan 1. The bottom two panels show the baseline scan, performed 20 min after gadolinium based contrast agent (GBCA) administration one month prior to ablation. Acq: acquisition. LSPV: left superior pulmonary vein, LIPV: left inferior pulmonary vein, RSPV: right superior pulmonary vein, RIPV: right inferior pulmonary vein, LAA: left atrial appendage, SD: standard deviation
