The muscular system is one of the largest organ systems of the human body. In almost every MR image, skeletal muscles are also displayed. Although muscular diseases encompass a huge and heterogeneous group of both hereditary and acquired disorders, in most cases of progressive disease, myopathy presents with focal or general muscle weakness, which is, however, an unspecific symptom. Since the clinical presentation of these disorders may be quite similar, there is a need for ancillary testing. Therefore, in principle, imaging techniques that offer differential diagnostic clues are urgently needed.
