“…21 Various NMR indices reflect different aspects of muscle anomalies and their interpretation has been detailed in a dog model of DMD. 25,31 Overall, NMR alterations observed here in the upper limb of patients correlated with those observed in the lower limbs of younger patients. Fat infiltration correlated with clinical assessments such as timed walking/running or rising from supine tests, manual muscle testing, MFM, or Brooke scales.…”

“…31,[34][35][36] It does not follow the same disease progression as fat infiltration 13,34 ; instead, T2 of muscle water appears to be highest in earlier stages of the disease. 15 In a study on corticosteroid therapy followup in young patients with DMD with very low fat infiltration, 35 investigators used NMRI and 1 H NMRS to measure fat fraction and T2 of water with the 6MWT, timed tests, and quantitative force measurements of the lower limb.…”

“…La même observation a été réalisée chez le GRMD, un modèle canin de la myopathie de Duchenne, plus proche du phénotype humain (Thibaud et al 2007 ;Thibaud et al 2012 ;Wang et al 2013 normaliser lorsqu'une thérapie génique restaure efficacement la protéine défective (Walter et al 2005 ;Pacak et al 2007 ;Yokota et al 2009). Plus récemment, plusieurs travaux ont confirmé ces observations, et amélioré notre compréhension des processus d'altération du T2 sur ces modèles animaux de dystrophie musculaire.…”

“…La fibrose endomysiale est fortement corrélée à la perte de fonction motrice chez les patients atteints de la maladie de Duchenne (Desguerre et al 2009). C'est pourquoi un pan de la recherche thérapeutique vise à bloquer voire à rendre réversible l'accumulation pathologique de tissu conjonctif (Zhou et Lu 2010 (Parzy et al 2007 ;Thibaud et al 2012 ;Wary et al 2015a). La décroissance T2 du signal des tissus est un processus multi-exponentiel complexe.…”

“…Dystrophic muscle tissue feature such as fibrosis, necrosis and abnormal vascularization could be evaluated by texture analysis (TA). Several successful attempts have already been made to identify abnormal muscle features using MRI [5][6][7][8][9][10][11][12][13]. In the light of these findings, it appears that MRI-TA could be a powerful image processing tool for a better assessment of diagnosis and therapy effectiveness.…”
