How Imaging Can Assist with Diagnosis and Monitoring of Disease in Myositis

To summarize recent findings and progression in the field of imaging of inflammatory myopathies. The most commonly used method is magnetic resonance imaging, and the article focuses on this technique, but covers also several other less frequently used or emerging methods.

A relatively good agreement exists regarding some technical parameters, area of investigation, and assessment of inflammatory activity and chronic damage using magnetic resonance imaging. There are inconsistent data available with respect to distribution of involvement in individual IIM subtypes. Ultrasound and other imaging methods lack the validation and still face many unresolved problems. Imaging plays a crucial role in the evaluation of impairment in patients with IIMs. The future research should be focused on standardization of each method in order to obtain comparable results and on defining the most appropriate indications of their use.
