Pfirrmann classification on T2WI has been the qualitative grading of intervertebral disc (IVD) degeneration which is difficult to classify subtle changes of degeneration. A quantitative and more sensitive classification system has been sought.

In this research, probability at zero displacement obtained from Q-space imaging (QSI) which is a quantitative diffusion-weighted MRI procedure made it possible to observe the effect of the regenerative antioxidant drug: N-Acetyl Cystaine on IVD degeneration which could not be observed by using T2 mapping.

Probability at zero displacement obtained from QSI has the possibility to be a novel biomarker of IVD degeneration.
