Phantom Fiber Crossing Results. (A) The top row illustrates the reconstruction tractography results for pathway 1, characteristic of cortical “U” fibers. The second row shows the tractography results across reconstruction methods in pathway 2 demonstrating successful traversal of the “U” fiber geometry. (B) Quantitative analysis based on the number of correct “U” streamlines demonstrated significant differences between all reconstruction methods with DTI providing the greatest number of correct streamlines. (C) Quantitative analysis based on the number of correct straight streamlines demonstrated that the ball-and-sticks reconstruction (0.01) generated the greatest number of correct streamlines while DTI and GQI were unable to produce any streamlines. DTI, diffusion tensor imaging; GQI, generalized q-sampling imaging; decon, deconvolution; M, mean; BSM, ball-and-sticks model. *Significance of at least p < 0.05.
