Synopsis

Keywords: MSK, Skeletal, Spine, TaggingThe reference standard for spinal-cord motion measurement is phase-contrast (PC) imaging. This approach, however, requires a dedicated phase correction during post processing, which renders clinical application very challenging. The objective of this work was to employ MR-tag imaging to directly visualize cervical spinal-cord motion in patients with spinal-canal stenosis and compare results with PC imaging. Among all patients, a good correlation between tag imaging and matched PC measurements was found (R² = 0.84). Hence, MR-tag imaging may well complement standard static imaging within clinical routine of patients with spinal-canal stenosis, reflecting dynamic spinal cord distress.
