Muscle Changes Detected with Diffusion-Tensor Imaging after Long-Distance Running

Abstract: A feasible method for DTI measurements of the upper legs was developed that fully included frequently injured muscles, such as hamstrings, in one single imaging session. This study also revealed changes in DTI parameters that over time were not revealed by qualitative T2-weighted MR imaging with fat suppression.

“…With the triexponential fit, the diffusion coefficient further decreases, suggesting that biexponential fitting does not fully differentiate between pure diffusion and other water motion processes and that introducing an additional intermediate component allows to further distinguish between them. The value of D 3 is more in range of MD values found in other organs such as muscle,44 heart,45 and brain 46…”

“…Change of apparent diffusion coefficient has been observed even in the Trunk muscles between before and after training 16) . Change of diffusion tensor parameters after long-distance running (marathon) also has been reported 17) . Marathon runners were scanned before, 2 days after and 3 weeks after marathon.…”

“…Peu ont exploré des pathologies musculaires (Zaraiskaya et al 2006 ;Qi et al 2008 ;Sigmund et al 2013 ;Sigmund et al 2014 ;Ponrartana et al 2015) dans le contexte de l'utilisation des variables de diffusion comme biomarqueurs ou comme outils d'évaluation. Le coefficient de diffusion apparent s'est logiquement révélé anormalement élevé dans les myopathies inflammatoires, tandis que le calcul de la fraction d'anisotropie a donné des résultats divergents (Ai et al 2014 ;Froeling et al 2015). Il n'y a pas encore eu d'analyse longitudinale de l'activité de la maladie ni de la réponse à un traitement.…”
