Synopsis

Keywords: Spinal Cord, Neuro, Myelin

Motivation: Discrimination between gray and white matter of the spinal cord remains challenging.

Goal(s): To investigate imaging techniques that best discriminate gray matter from white matter.

Approach: Inhomogeneous magnetization transfer (ihMT) and phase-sensitive inversion recovery (PSIR) have been reported effective in discriminating between gray and white matter. Myelin-sensitive inversion recovery (MySIR) was compared with ihMT and PSIR for evaluating the discriminability between gray and white matter.

Results: MySIR had the highest contrast ratio compared to ihMT and PSIR.

Impact: MySIR was superior to ihMT and PSIR in discriminating gray matter from white matter, and MySIR can be useful as a new myelin-specific MR imaging technique for spinal cord segmentation.
