- To understand the relevance of spine involvement in Axial Spondyloarthritis (SpA). - Description of characteristic spinal MRI lesions in Axial SpA: Inflammatory and structural changes, with radiographic correlation. - To discuss the role of MRI as a biological marker of disease activity: definition of positive MRI of the spine, and utility for monitoring.

I- IMAGING AND AXIAL SpA A. Diagnostic Criteria of axial SpA B. Spine involvement in Axial SpA II- IMAGING OF THE SPINE IN AXIAL SpA A.Spine MRI Protocol B.Characteristic MRI findings with Plain film and CT correlation: 1. Inflammatory changes: Anterior and Posterior Spondylitis, Spondylodiscitis, Arthritis of facet joints, costovertebral joints, and costransverse joints, and Enthesitis of spinal ligaments. 2. Structural changes: Fatty depositions, Erosions, Syndesmophytes, and Ankylosis. C. Differential Diagnosis III- MRI AS A BIOLOGICAL MARKER OF DISEASE ACTIVITY A. Definition of positive MRI of the Spine for inflammation (according to ASAS Working Group) B. Monitoring: Disease activity and treatment response
