Abstract
The recently-proposed MP2RAGE sequence was purposely optimized for cervical spinal cord imaging at 3T. Sequence parameters were chosen to optimize gray/white matter T <sub>1</sub> contrast with sub-millimetric resolution and scan-time < 10 min while preserving reliable T <sub>1</sub> determination with minimal B <sub>1</sub> <sup>+</sup> variation effects within a range of values compatible with pathologies and surrounding structures. Results showed good agreements with IR-based measurements, high MP2RAGE-based T <sub>1</sub> reproducibility and preliminary evidences of age- and tract-related T <sub>1</sub> variations in the healthy spinal cord.
