Research Abstract

This study evaluated if the major diffusion tensor imaging (DTI) metrics of the brain and the spinal cord can become the quantitative metrics for noninvasive evaluation of intractable diseases of the central nervous system.
Significant alterations in the major DTI metrics were observed in sporadic amyotrophic lateral sclerosis, multiple sclerosis, and neuromyelitis optica spectrum disorders, despite no abnormality on the routine MRI sequences. The abnormalities detected on DTI are thought to reflect axonal loss and/ or demyelination. In sporadic amyotrophic lateral sclerosis, the DTI abnormalities correlated strongly with the scores which determine disease severity or progression. In conclusion, DTI is considered a sensitive technique to detect the microstructural abnormalities of the brain and the spinal cord in the intractable diseases of the central nervous system; and can be used to noninvasively quantify the severity or progression of these diseases.
