Whole-body MRI in arthritis

Area of Science:

• Radiology and Imaging
• Rheumatology
• Medical Technology

Background:

• Whole-body MRI (wbMRI) provides high-resolution, full-body imaging, increasingly used for systemic conditions.
• Its comprehensive coverage is valuable for diagnosing and monitoring systemic arthritides, which often involve multiple sites.

Purpose of the Study:

• To overview current wbMRI technology for inflammatory arthritis.
• To discuss wbMRI's role in diagnosing and monitoring multifocal inflammatory conditions.
• To provide a general wbMRI protocol for non-oncologic musculoskeletal applications.

Main Methods:

• Review of current wbMRI technology and applications in inflammatory arthritis.
• Comparison of wbMRI sensitivity and reproducibility against radiography, ultrasound, and targeted MRI.
• Discussion of customizable scan protocols and benefits for monitoring autoimmune diseases.

Main Results:

• wbMRI enables early detection of subclinical disease foci, offering a more accurate assessment of total disease burden.
• wbMRI demonstrates superior sensitivity and reproducibility compared to conventional methods, especially for intraosseous and axial involvement.
• The technology is advantageous for monitoring autoimmune diseases due to its comprehensive nature and lack of ionizing radiation.

Conclusions:

• wbMRI is a valuable tool for diagnosing and monitoring systemic inflammatory arthropathies.
• Further research is required to validate standard protocols, assess cost-effectiveness, and integrate wbMRI into routine clinical practice.
• wbMRI holds significant potential for improving diagnostic accuracy and patient outcomes in inflammatory arthritis.
