Limb-girdle muscular dystrophies (LGMD) are a group of autosomal dominantly or recessive inherited muscular dystrophies that also present with primary proximal (limb-girdle) muscle weakness, involving the shoulder and pelvic girdles, distinct phenotypic or clinical characteristics are recognized. MRI has great potential for non-invasive characterization of muscle properties in LGMDs utilizing techniques such as Dixon-based imaging for fat-water quantification and diffusion MRI for probing muscle microstructure. The aim of this study was to compare quantitative MRI measurements from Dixon-based imaging and DWI in the thigh muscles of adults with LGMDs and healthy volunteers.
