Tendon exhibits changes in T2, T2*, and resonant frequency as a function of its orientation with respect to B0. An ultrashort echo time (UTE) sequence was employed to characterize the frequency of fresh bovine digital flexor tendon at angles of 0⁰ to 90⁰ relative to B0, causing a maximal frequency shift of 1.0 ppm. Factors that could influence the frequency of tendon were evaluated. It was found that the frequency of tendon was affected by the enclosing container, but not the geometry of the tendon.
