MRI

• MRI from muscles may be helpful in the diagnosis of polymyositis and dermatomyositis.
• 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 active disease and muscle edema
  • Fatty infiltration of muscles
  • Muscle calcification
