(A) Projection DSI tractogram looking onto the anterior and anterolateral walls of a normal rat heart. The visualized fibers have helix angles consistent with subepicardial (green-yellow) and mid-myocardial (blue) myofibers and are arranged in an orderly and dense network of myofiber sheets. (B) A hematoxylin and eosin stained section of the myocardium (outlined by the black lines in Panel A) showing a similar structure. (C, D) A normal rat heart viewed from (C) its lateral wall and (D) its apex. Subendocardial (pink) and mid-myocardial (blue) fibers cross over each other in separate transmural planes that do not intersect or make contact. Reproduced with permission from Sosnovik et al [27].
