3 Key Takeaways
Plain English Summary- 01Core Finding
Recommendations were formulated based on evidence and expert opinion and refined iteratively until consensus was achieved.
- 02Study Evidence
Tested in a expert consensus / perspective at the guideline and clinical review stage.
- 03Practical Meaning
Expert perspective or consensus guidance synthesizing existing studies rather than reporting new randomized trial data.
What This Means for You
These recommendations provide the first evidence-based guidance for the use of imaging in PMR, reinforcing clinical assessment as the cornerstone of diagnosis and positioning imaging as a context-driven adjunct.
The Discovery
The study aims to develop international recommendations for the use of imaging in the diagnosis and assessment of polymyalgia rheumatica (PMR). An international, multidisciplinary task force of 30 members from 12 countries was convened; the European Alliance of Associations for Rheumatology standard operating procedures were followed. Six clinical key questions addressing the role of imaging (ultrasound, magnetic resonance imaging, and 18 F-fluorodeoxyglucose positron emission tomography) in diagnosis, monitoring, outcome prediction, and technical aspects in PMR were the basis for a systematic literature review. Recommendations were formulated based on evidence and expert opinion and refined iteratively until consensus was achieved. The level of agreement was assessed by voting. Three overarching principles and 7 recommendations were developed. PMR remains primarily a clinical diagnosis. Imaging is neither required to confirm PMR in patients with a high clinical probability of the disease nor to exclude PMR in case of low clinical probability. Imaging is most useful in patients with intermediate pretest probability (ie, atypical presentations or suspected alternative/overlapping conditions). No single imaging modality demonstrated sufficient accuracy to be recommended as a first-line test; therefore, imaging should be individualised according to clinical presentation, differential diagnoses, access, and local expertise. Vascular imaging should be performed when overlap with giant cell arteritis is suspected, whereas systematic screening for subclinical vasculitis is not supported by current evidence. Utilising imaging for disease monitoring or outcome prediction is currently not recommended.
How It Works, Simply
This immunology research focuses on adaptive cytokine & immune-cell regulation. Researchers evaluated it using an expert consensus / Perspective at the guideline and clinical review stage of medical research.
