PURPOSE OF REVIEW: The idiopathic inflammatory myopathies are diseases that can
be difficult to diagnose and evaluate, but diagnosis has been improved by modern
imaging techniques. Advances in imaging continue to be made. Therefore, it is
necessary to evaluate the implications of these advances for the diagnosis,
understanding, and management of muscle diseases. RECENT FINDINGS: There have
been advances in imaging across multiple modalities. Several new radiotracers
show an improved ability to focus on inflammation better than older agents.
Magnetic resonance spectroscopy has shown the ability to diagnose several
idiopathic inflammatory myopathy mimics. MRI reveals previously unknown areas of
disease when used for full-body imaging. Ultrasound has the ability to
differentiate inclusion body myositis from other myopathies. SUMMARY: Currently,
MRI and ultrasound offer the most information about these diseases in a given
patient, and new advances in these fields have served to only make them more
useful. New advances in nuclear imaging and magnetic resonance spectroscopy are
showing that they have utility as well, and advances in these techniques may
allow them to come to the forefront in evaluating difficult idiopathic
inflammatory myopathy patients.
