A schematic of the semi-automated tractography and hippocampal subfield fiber density calculation workflow. The dMRI image (A) was used to derive the fiber orientation distribution image (B1, with magnification inset B2), which was then used to perform whole-brain probabilistic tractography (C). The T1- weighted anatomical image (D) was used to determine the gray matter-white matter boundary (E) and to segment the hippocampal subfields (F). The hippocampal subfields were defined as seed points for tractography of the individual subfields (G) from which connectomes were defined (H).
