Key result
Imaging modalities, particularly MRI, are sensitive to pathology in idiopathic inflammatory myopathies and may contribute to more rapid diagnosis, treatment planning, and disease monitoring.
Why the study?
MRI limitations such as cost, accessibility, scan delays, and contraindications prompted exploration of other imaging techniques to diagnose idiopathic inflammatory myopathies and monitor therapy response.
What is the utility of imaging modalities in the diagnosis and monitoring of idiopathic inflammatory myopathies?
What is the utility of imaging modalities in the diagnosis and monitoring of idiopathic inflammatory myopathies?
Imaging modalities like MRI are useful for diagnosing and monitoring idiopathic inflammatory myopathies, but further research is needed to establish their full validity and utility.
Supports selective MRI use in IIM evaluation; leaves open validation of diagnostic performance and standardization.
INTRODUCTION: Idiopathic inflammatory myopathies (IIM) are a heterogeneous group of muscle diseases that carry a significant morbidity and mortality risk. The utilization of imaging in the diagnostic pathway of IIM is therefore important to obtain early diagnosis and even monitor patients over time. Areas covered: Magnetic resonance imaging (MRI) has been the main imaging modality used to detect myositis but limitations include cost and accessibility, leading to delays in time to scan, and patient contraindications. This has led to the exploration of other imaging techniques to diagnose and monitor response to therapy. This article is based primarily on a literature search via PubMed using Boolean terms 'myositis' and the various imaging modalities. Expert opinion: Imaging is sensitive to pathology in IIM and may contribute to the diagnostic process. Learning how specific imaging features can distinguish different forms of IIM may allow more rapid diagnosis of myositis subtype and treatment planning, and to monitor disease activity particularly in patients who respond poorly to treatment. However, more work is needed to investigate the validity and relative utility of these imaging modalities.

Paramalingam et al. (2019) conducted a review in Idiopathic inflammatory myopathies (IIM). Imaging modalities (including MRI) was evaluated. Imaging modalities, particularly MRI, are sensitive to pathology in idiopathic inflammatory myopathies and may contribute to more rapid diagnosis, treatment planning, and disease monitoring.
