Identification of Infarct Border Zone Using Late Gadolinium Enhanced MRI in Rats.

The extent of myocardial remodeling in LVFW during the post-infarct healing process determines the contractile behavior in the LVFW and influences long-term outcomes. Automated identification of infarct, BZ, and remote myocardium regions using LGE-MRI is a step towards image-based characterization of the heterogenous remodeling in the LVFW. Additionally, our algorithm enables the simple definition of a BZ of varied size and could allow us to better understand the influence of distinct regional remodeling events on organ-level function as MI proceeds from early-stage scarring to late-stage remodeling.
