Proton NMR relaxation properties (T2*) in human Achilles tendon were assessed in vivo at 3T and 7T field strength. 3D-UTE sequence (capable of minimum TE=0.07ms) was used with the set of 8 different TE {min 0.07 ms, max 4.00 ms}. T2* were found to be statistically significantly different between two field strengths in the most of the selected anatomical regions. Bulk T2* was 0.980.08ms (3T) and 0.410.10 (7T). T2 may prospectively serve as a marker for diagnosis of early tendon diseases.
