Texture analysis provides quantitative image analysis based on mathematically calculated features. A high number of features calculated with texture analysis showed to be significantly different between the intervertebral discs with and without annular fissuring that had been classified from CT discograms. When the features based on T2-weighted images were used for classification by "Random Forest" a very high accuracy in differentiating between discs with and without annular fissuring was achieved.
