SIR, MRI is increasingly employed in the investigation of suspected neuromuscular disease. High signal intensity on fat-suppressed T2-weighted and short T1 inversion recovery (STIR) muscle MR images is found in inflammatory myositis [1]. MRI is sensitive for localizing non-homogeneous muscle abnormalities allowing biopsy to be targeted [2]. Previous studies have shown that non-targeted single site biopsy may lead to the diagnosis being missed in approximately one-third of cases [3].
Suspected muscle disease is a
