Ex vivo imaging. Ex vivo short axis images in a representative pig heart from base (top) to apex (bottom). Left column shows high resolution T1 weighted images, middle column shows 2D-PSIR images and right column show 3D-IR images. The green line denotes the epicardial border and the red line denotes the endocardial border. The infarct is delineated in yellow. Note the difference in infarct size between the T1w-sequence and the IR-LGE sequences as showed by the white arrows in the top two rows.
