In this study we found moderate correlation between normalized sodium signal which is believed to be related to glycosaminoglycan content in cartilage and Achilles tendon and quantitative morphological VIMAT Score. Relative low correlations suggest that sodium MRI and VIMATS are complementary markers - VIMATS for macroscopic changes and the normalized sodium signal as a marker of GAG content increase due to accompanying or preceding degeneration Sodium imaging may have the potential to detect early stages of Achilles tendon degeneration and partial tear.
