Tractograms of the infarcted region color-coded by (A) the helix angle (HA), and (B) propagation angle (PA). Tractograms of the remote zone color-coded by (C) the HA, and (D) PA. While myofibers in the remote zone are coherent and follow the typical transmural helical orientation, myofibers in the infarct zone exhibit disarray leading to an increase in PA. Bar plots comparing (E) PA, (F) HAvariance, (G) MD, and (H) FA reveal significant differences in microstructure and myofiber organization between the infarcted and remote zones.
