Dermatomyositis (DM) and polymyositis (PM) commonly cause weakness of the thigh muscles. However, it is debated whether DM and PM affect similar thigh muscles. Muscle oedema on fat-suppressed MRI sequences is thought to represent active inflammation. In this study, we aimed to assess which thigh muscle groups are preferentially inflamed in DM and PM, respectively, using short-tau inversion-recovery MRI sequences.

Abstract

Dermatomyositis (DM) and polymyositis (PM) commonly cause weakness of the thigh muscles. However, it is debated whether DM and PM affect similar thigh muscles. Muscle oedema on fat-suppressed MRI sequences is thought to represent active inflammation. In this study, we aimed to assess which thigh muscle groups are preferentially inflamed in DM and PM, respectively, using short-tau inversion-recovery MRI sequences.
