| MRI image acquired approx. 15 minutes after contrast injection and prior to ablation. (The LA is the gray, horizontally oriented structure above the spine in the center of the image) | MRI image acquired approx. 15 minutes after contrast injection and after the ablation was performed. Sections of the LA wall which were ablated appear as hyper-enhanced pixels in the LA wall. |
| MRA Image | Segmentation of LGE-MRI Image |
| The MRA is acquired after contrast injection and before the LGE-MRI images above. This image type highlights the blood pool of the LA and some surrounding structures. | manual segmentation of the LA is performed on pre- and post-ablation LGE-MRI images by the CARMA team. Here the blue mask denotes the LA wall and the orange the blood pool. |
