Cellular sizes in skeletal muscle are significantly larger than in the brain. Therefore standard spin-echo (SE)-DTI with inherently short diffusion times may lack sensitivity for the study skeletal muscle of neuromuscular disorders (NMDs). Alternatively, stimulated-echo (STE-)DTI allows for much longer diffusion times, increasing sensitivity to cell size. Due to the challenges presented by fat replacement STE-DTI has not been previously applied in NMDs. Here, we show that STE-DTI is feasible in Becker Muscular Dystrophy patients, and can detect FA differences compared to healthy controls in mildly affected muscles.
