Abstract:
Modern imaging including ultrasound, MRI and PET have all played a pivotal role in characterizing the distinctive musculotendinous pathology that is now recognized to define PMR. Each of these modalities offers inherent advantages and disadvantages relative to availability, cost and radiation exposure, although MRI and hybrid PET/CT are particularly capable of detecting highly sensitive and specific findings, and thus should be considered reliable tools for PMR diagnosis in everyday clinical practice. By contrast, the utility of imaging for monitoring disease activity and predicting long-term clinical outcomes represents areas of ongoing research interest. This narrative review outlines the invaluable contribution made by imaging to our current understanding of PMR as a distinct disease entity and evaluates the diagnostic performance of available modalities together with their future potential for disease activity assessment and prognostication.
Insights
Modern imaging techniques like MRI and PET/CT are crucial for diagnosing polymyalgia rheumatica (PMR) by identifying characteristic muscle and tendon issues. Further research is needed to determine their role in monitoring disease activity and predicting patient outcomes.
Area of Science:
- Rheumatology
- Radiology
- Medical Imaging
Background:
- Polymyalgia rheumatica (PMR) is increasingly understood through its distinct musculotendinous pathology.
- Modern imaging modalities have become essential in characterizing this pathology.
Purpose of the Study:
- To review the role of imaging in diagnosing PMR.
- To evaluate the diagnostic performance of various imaging modalities for PMR.
- To explore the future potential of imaging in assessing disease activity and prognosis.
Main Methods:
- Narrative review of current literature on imaging in PMR.
- Evaluation of ultrasound, MRI, and PET/CT for PMR diagnosis.
- Discussion of advantages and disadvantages of each modality.
Main Results:
- Ultrasound, MRI, and PET have been pivotal in defining PMR pathology.
- MRI and PET/CT demonstrate high sensitivity and specificity for PMR diagnosis.
- Imaging is considered reliable for everyday clinical practice in PMR diagnosis.
Conclusions:
- Imaging significantly contributes to understanding PMR as a distinct disease.
- MRI and PET/CT are valuable tools for PMR diagnosis.
- The utility of imaging for monitoring disease activity and prognosis requires further investigation.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
