Diffusion tensor imaging is being increasingly used as a means to elucidate the brain's fiber structure. High spatial resolution is needed to capture details of the anatomy for tractography. However, image deteriorating factors such as low contrast-to-noise ratio, partial volume effects and subject's displacements affect the analysis.
