Application of muscle MRI in diagnosis of hereditary myopathies

MRI is the most clear and accurate imaging technique for detecting muscle involvement. In recent years, MRI has been widely used in diagnosis and follow⁃up of muscle disorders. A variety of muscle disorders have specific selective muscle involvement patterns. There is accumulating evidence that patterns of involved muscles shown by muscle MRI can help delineate the possible diagnoses. The aim of this paper is to state MRI manifestations of hereditary myopathies, so as to improve neurologist's understanding of muscle MRI and promote application of muscle MRI in diagnosis of hereditary myopathies
