1 Percentage appearances of MRI findings in the MSAs/MAAs-positive and MSAs/MAAs-negative groups.
Percentage appearances of MRI findings in the MSAs/MAAs-positive and MSAs/MAAs-negative groups. The percentage appearances of subcutaneous HSI, fascial HSI, peripheral/diffuse/patchy distribution of HSI in muscle and honeycomb/foggy/SHSI patterns of HSI in muscle were compared between the MSAs/MAAs-positive and MSAs/MAAs-negative groups. STIR and Gd-T1WI images were evaluated. *p<0.05. ADM, amyopathic dermatomyositis; DM, dermatomyositis; Gd-T1WI, gadolinium-enhanced fat-suppressed T1-weighted imaging; HSI, high signal intensity; IIM, idiopathic inflammatory myopathy; MAAs, myositis-associated autoantibodies; MSAs, myositis-specific autoantibodies; PM, polymyositis; SHSI, strong high signal intensity; STIR, short-tau inversion recovery.
