Rheumatic diseases of the spine: imaging diagnosis.

Area of Science:

• Rheumatology
• Radiology
• Spinal Imaging

Background:

• Spinal involvement is prevalent in spondyloarthritides and rheumatoid arthritis, with the cervical spine being particularly affected in rheumatoid arthritis.
• Rheumatoid arthritis of the cervical spine presents distinct radiologic patterns of atlantoaxial instability.
• Axial involvement is a hallmark of spondyloarthritides, showing destructive and reparative changes on plain X-rays.

Purpose of the Study:

• To highlight the role of Magnetic Resonance Imaging (MRI) in evaluating cervical spine involvement in rheumatoid arthritis and spondyloarthritides.
• To emphasize MRI's capability in detecting active inflammation, bone edema, and synovitis.
• To underscore MRI's impact on early diagnosis, prognosis, and treatment planning for these conditions.

Main Methods:

• Magnetic resonance imaging (MRI) is identified as the primary imaging modality.
• MRI is utilized to assess spinal cord and nerve root repercussions from atlantoaxial instability in rheumatoid arthritis.
• MRI is employed to detect inflammatory changes in spondyloarthritis, including cases with normal plain X-ray findings.

Main Results:

• MRI effectively evaluates the consequences of atlantoaxial instability on the spinal cord and nerve roots in rheumatoid arthritis.
• MRI identifies active inflammation parameters like bone edema and synovitis in rheumatoid arthritis.
• MRI enables early diagnosis of non-radiographic axial spondyloarthritis when plain X-rays are normal.

Conclusions:

• MRI is crucial for diagnosing and managing cervical spine involvement in rheumatoid arthritis and spondyloarthritides.
• The use of MRI has revolutionized the understanding and management of spondyloarthritis, enabling earlier diagnosis and better prognosis assessment.
• MRI facilitates comprehensive assessment, including prognosis and treatment planning, for patients with inflammatory spinal diseases.
