Imaging in polymyalgia rheumatica: which technique to use?

Area of Science:

• Rheumatology
• Medical Imaging
• Inflammatory Disorders

Background:

• Polymyalgia rheumatica (PM) is an inflammatory rheumatic condition causing pain and stiffness in the neck, shoulders, and pelvic girdle.
• PM may be associated with giant cell arteritis.
• Current diagnosis lacks a gold standard, necessitating comprehensive inflammatory assessment and imaging.

Purpose of the Study:

• To review the current applications of various imaging modalities in the diagnosis and follow-up of polymyalgia rheumatica.
• To clarify the advantages and disadvantages of different imaging techniques for PM.
• To provide an updated overview based on literature from the last 10 years.

Main Methods:

• Literature review of studies published in the last 10 years.
• Analysis of imaging techniques used in polymyalgia rheumatica.
• Evaluation of imaging for diagnosis, complications, and association with giant cell arteritis.

Main Results:

• Multiple imaging techniques including radiography, ultrasound, MRI, and PET/CT are utilized in PM assessment.
• Each imaging modality presents unique benefits and limitations for evaluating PM.
• Imaging plays a crucial role in disease stratification and monitoring PM patients.

Conclusions:

• Imaging is integral to the diagnostic process and follow-up of polymyalgia rheumatica.
• Understanding the strengths and weaknesses of different imaging methods aids in optimal patient management.
• Further research may refine the role of specific imaging techniques in PM.
