Patterns of spinal new bone formation in patients with axial spondyloarthritis, psoriatic arthritis, rheumatoid arthritis and healthy controls: a low-dose CT study.

Key Points

• This research aims to identify and compare patterns of new bone formation in axial spondyloarthritis, psoriatic arthritis, rheumatoid arthritis, and healthy controls.
• Conducted low-dose CT imaging to assess new bone formation patterns
• Compared findings across axial spondyloarthritis, psoriatic arthritis, rheumatoid arthritis, and healthy controls
• Analyzed locations and types of bone formations such as syndesmophytes and osteophytes
• Axial spondyloarthritis showed frequent marginal syndesmophytes, especially in the thoracic spine.
• Other groups primarily exhibited osteophytes with no unique pattern of new bone formation.
• No consistent new bone formation patterns distinguished the groups comprehensively.
