In this study, 7 human cadaveric rotator cuff tendons
were used to compare orientation-dependent value changes
using T2, T2*, and MT techniques. We found that mean
percent change was up to 38% using T2, up to 92% using
T2*, and up to 15% using OSR. OSR measured with the
UTE-MT technique may be more useful than T2 and T2* due
to the strong dipolar-dipolar influence on the latter
two biomarkers.
