Fiber tractography of normal human atria, obtained from diffusion-weighted MRI imaging of ex-vivo samples. (Top) Atrial geometry. Left column (A, B) shows standard T1-weighted MRI images of the anatomy. Middle column (C, D) External surface view of the fiber tracts. Right column (E, F) anterior view of atrium. (Bottom) Changes in fiber tract orientation with depth in the left atrial wall of a single subject. Color code on right measures the similarity to the fiber tract direction on the epicardial surface.
