Overview
MRI from muscles may be helpful in the diagnosis of polymyositis and dermatomyositis. Findings on MRI suggestive of polymyositis and dermatomyositis include areas of high signal intensity reflecting an active disease and muscle edema, fatty infiltration of muscles, and muscle calcification.
MRI
- MRI from muscles may be helpful in the diagnosis of polymyositis and dermatomyositis.[1][2][3][4][5]
- MRI is required for follow-up, and to identify the best site for muscle biopsy.
- Findings on MRI suggestive of polymyositis and dermatomyositis include:
- Areas of high signal intensity reflecting an active disease and muscle edema
- Fatty infiltration of muscles
- Muscle calcification
