We obtained consistent T2, T1rho, and sodium concentration in intervertebral discs from normal subjects using spin-lock, and ultra-short echo-time spiral sequence with a dual-tuned multi-channel RF torso coil at 3T human scanner. These MR-based measures of intervertebral discs may play an important role as imaging biomarkers for early diagnosis of degenerative disc disease..
