Characterizing in vivo spinal lesions in amyotrophic lateral sclerosis (ALS) is crucial to explore the anatomic structures affected by the disease more precisely. In this study we combined for the first time DW, MT imaging and atrophy measurements to evaluate the cervical spinal cord of ALS patients. In the ventro-lateral aspect of the cervical cord, significant differences were detected in FA, radial diffusivity and MTR. Spinal atrophy was correlated with some clinical measures. From a clinical perspective, it could provide new non-invasive tools for early diagnostic, measuring disease progression in ALS.
