Key result
MRI evaluates skeletal muscle disease burden, guides biopsies, and assesses function in inflammatory myopathies.
Why the study?
Various imaging modalities exist for skeletal muscle evaluation, but their utility and advances in inflammatory myopathies require clarification.
Magnetic resonance imaging, including newer functional techniques, is the standard for evaluating disease burden and guiding biopsy in inflammatory myopathies.
No takes yet. Share an insight, caveat, or question.
May support MRI for myositis assessment; hypothesis-generating and requires prospective validation before practice change.
Kuo et al. (2007) conducted a review in Skeletal muscle diseases and inflammatory myopathies. Skeletal muscle imaging (MRI, CT, ultrasound, radiography) was evaluated. Magnetic resonance imaging is a useful modality for evaluating skeletal muscle disease burden, elucidating biopsy targets, and acquiring functional information in inflammatory myopathies.
