We tested the use of diffusion tensor imaging with three-dimensional fiber tracking (DTI-FT) for the assessment of spinal sensory tract lesions. We systematically examined the relationships between tract lesions quantified with DTI-FT, and somatosensory dysfunction assessed with quantitative sensory testing (QST) and laser evoked potentials (LEP), in patients with syringomyelia.
