Thigh muscle MRI in immune-mediated necrotising myopathy: extensive oedema early muscle damage and role of anti-SRP autoantibodies as a marker of severity

摘要

ObjectivesThe aims of this study were to define the pattern of muscle involvement in patients with immune-mediated necrotising myopathy (IMNM) relative to those with other inflammatory myopathies and to compare patients with IMNM with different autoantibodies.
