Summary

Ankylosing spondylitis diagnosis is improved with MRI, detecting early sacroiliitis and spinal inflammation. This imaging is crucial for guiding treatment with new biologic agents like TNF-alpha inhibitors.

Area of Science:

  • Radiology
  • Rheumatology
  • Immunology

Background:

  • Ankylosing spondylitis (AS) is a primary spondyloarthropathy (SpA) characterized by sacroiliitis and spinal inflammation.
  • Early detection of inflammatory back pain and spinal lesions is vital for effective management.
  • Conventional X-rays have limitations in visualizing early disease activity.

Purpose of the Study:

  • To review current MRI techniques for diagnosing AS and SpA.
  • To present novel MRI approaches for assessing spinal inflammation.
  • To highlight MRI's role in guiding treatment with biological agents.

Main Methods:

  • Magnetic resonance imaging (MRI) techniques, including short tau inversion recovery (STIR) and gadolinium-diethylenetriamine pentaacetic acid (DTPA) contrast enhancement.
  • Review of available scoring tools for spinal inflammation.
  • Presentation of novel MRI approaches.

Main Results:

  • MRI effectively visualizes early sacroiliitis and spinal inflammation, including spondylitis and spondylodiscitis.
  • MRI is particularly useful in early/active disease, young women, children, and for differentiating septic sacroiliitis.
  • MRI offers superior sensitivity compared to conventional X-rays for detecting spinal inflammation.

Conclusions:

  • MRI is a sensitive tool for early diagnosis and monitoring of ankylosing spondylitis and spondyloarthropathies.
  • Advanced MRI techniques aid in assessing disease activity and guiding therapy with anti-tumour necrosis factor-alpha (TNF-alpha) agents.
  • Improved spinal imaging is essential given the efficacy of novel biological therapies in SpA.
