Inflammatory and chronic structural changes are objective signs of axial spondyloarthritis. In the sacroiliac joints (SIJs), inflammation (sacroiliitis) can be visualized as bone marrow edema, whereas chronic structural changes are visualized as fat metaplasia, erosions, sclerosis, or ankylosis in the area of the SIJ. In the spine, bone marrow edema in the vertebral bodies represents spondylitis but can also affect the facet and the costovertebral and costotransverse joints (arthritis), whereas structural changes are visualized as fat metaplasia, sclerosis or syndesmophytes and ankylosis at the vertebral edges.
炎症和慢性结构改变是轴性脊柱关节炎的客观体征。在骶髂关节（SIJ）中，炎症（骶髂关节炎）可表现为骨髓水肿，而慢性结构改变则表现为SIJ区域的脂肪化生、侵蚀、硬化或强直。在脊柱中，椎体的骨髓水肿代表脊柱炎，但也可影响小关节以及肋椎关节和肋横突关节（关节炎），而结构改变则表现为椎体边缘的脂肪化生、硬化或骨桥形成及强直。
