The aim of this study was to investigate the ability of diffusion tensor imaging (DTI) and T2 measurements to detect changes due to healing in athletes with muscle tears. 13 professional athletes were imaged within 2 days of injury and at the point that they returned to training. Regions of interest depicting the tear were drawn at visit 1 and were propagated to parameter maps from both visits taking into account motion between images. The study showed significant differences in DTI parameters and T2 values between visits, implying that these measures may be useful quantitative markers in assessing muscle healing.
