Magnetic resonance imaging in ankylosing spondylitis

Area of Science:

• Rheumatology
• Radiology
• Medical Imaging

Background:

• Ankylosing spondylitis is a chronic inflammatory disease primarily affecting the spine and sacroiliac joints.
• Accurate assessment of active inflammation is crucial for monitoring disease progression and treatment response.

Purpose of the Study:

• To review recent advancements in MRI techniques for evaluating active inflammation in ankylosing spondylitis.
• To highlight the role of MRI in quantifying disease activity and measuring therapeutic intervention effects.

Main Methods:

• Review of recent literature and randomized controlled trials.
• Focus on MRI techniques for characterizing spinal and sacroiliac joint inflammation.
• Discussion of MRI's capabilities and limitations in ankylosing spondylitis assessment.

Main Results:

• MRI can now characterize the extent and morphology of inflammation in ankylosing spondylitis.
• Published trials show MRI-detectable regression of spinal inflammatory lesions with anti-tumour necrosis factor agents.
• The utility of MRI for early diagnosis of spondyloarthritis is increasingly recognized.

Conclusions:

• MRI techniques are pivotal for the early identification of ankylosing spondylitis.
• These advancements facilitate timely and targeted therapeutic interventions.
• MRI plays a critical role in managing patients with ankylosing spondylitis.
