Synopsis

Keywords: Spinal Cord, Relaxometry, T1rho dispersion

Motivation: R1rho imaging can provide novel information on dynamic processes within tissues, allowing for a more comprehensive analysis of the parameters of chemical exchange and/or intrinsic microstructure.

Goal(s): To examine the feasibility of R1rho imaging in spinal cord.

Approach: We performed high resolution R1rho imaging in the swine spinal cord of swine spine specimens.

Results: The results showed that the dispersion is measurable in both spinal white matter and gray matter, suggesting that R1rho dispersion may have potential to characterize the de/remyelination and nerve injuries/repairs in neurological disorders.

Impact: The study suggested that R1rho dispersion is measurable in spinal cord, which may have potential to characterize the de/remyelination and nerve injuries/repairs in spinal cord disorders.
