Magnetic resonance imaging (MRI) is considered to be the best imaging method to evaluate the IVD degeneration. However, grading systems for degeneration severity evaluation are based on qualitative descriptions of disc image, which impairs the detection of small changes in intervertebral discs. In order to obtain a tool for objective and continuous grading of IVD degeneration. Fractal method was used to analyze the spatial distribution of intervertebral disc signals. We found that fractal dimension value displayed the strongest association with the clinical grading of disc degeneration severity, suggesting that IVD fractal analysis is a suitable tool for objective and continuous IVD degeneration classification.
