This study introduces a methodology for detecting subtle variations in tissues with very rapid T2* decay through a difference image ultra-short T2* mapping technique using a 3D cones k-space trajectory. The new method is demonstrated in both a normal and surgically repaired Achilles tendon. The resulting UTE images were differenced and T2* values were calculated using a mono-exponential least squares fit on a voxel by voxel basis. The ultrashort T2* maps yield very consistent short T2* values in healthy tendon of 0.3 – 0.5 ms, while notable variations and elevations of T2* values are observed in the surgically repaired tendon.
