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.
