DT-MRI-based fiber tractography allows non-invasive
estimation of three-dimensional muscle architecture;
however, DT-MRI in the leg suffers from low SNR, which
can introduce error in the estimation of diffusion
tensor eigenvectors used for tract propogation. This
study assesses the effect of anisotropic smoothing on
fiber tracking measures in the medial gastrocnemius
muscle in healthy subjects.
