Human Fiber Length Results. To quantitatively evaluate length estimates the streamline lengths were multiplied by the probability. Results shown indicate significant differences between model-free (GQI, GQI Decon., DSI, and DSI Decon.) and ball-and-sticks (BSM 0.01, BSM 0.03) reconstructions. Additionally, single tensor (DTI) reconstruction showed a significantly lower modal streamline length compared to all other reconstruction methods tested. DTI, diffusion tensor imaging; BSM, ball-and-sticks model; DSI, diffusion spectrum imaging; GQI, generalized q-sampling imaging. *Significance of at least p < 0.05.
