Mono-exponential curve-fitting for T2* calculation in AT can lead to misinterpretation of the results. The suggested algorithm for bi-exponential T2* fitting enables T2* to be a robust parameter that correlates with the actual clinical condition of the patient's tendon. T2* short may be a predictive marker for the probability of an AT rupture, as well as for a re-rupture after surgery. Bi-exponential fitting, although it is computationally more demanding, is also more precise and also allows distinguishing between bound and free water molecules.
