In Vivo Intervertebral Disc Characterization Using Magnetic Resonance Spectroscopy and T1ρ Imaging

Abstract

This study demonstrated a relationship between in vivo MRS spectroscopy (water content and PG content), imaging parameters (T1ρ and Pfirrmann grade), discography results, and clinical self-assessment, suggesting that MRS-quantified water, PG, and MR T1ρ relaxation time may potentially serve as biomarkers of symptomatic IVDD.
