Axial spondyloarthritis (axSpA) is a chronic rheumatic disease characterised by inflammatory back pain and several other disease manifestations and comorbidities. The 2009 ASAS classification criteria differentiate between the classical ankylosing spondylitis or radiographic axSpA and non-radiographic axSpA based on the presence or absence of definite radiographic changes in the sacroiliac joints. Importantly, back pain in patients with axSpA may well have reasons other than axial inflammation or new bone formation. There are several important differential diagnoses such as diffuse idiopathic skeletal hyperostosis and osteitis condensans. This review summarises recent publications concerning the performance of imaging modalities in the field, such as conventional radiography, magnetic resonance imaging, computed tomography and dual energy x-ray absorptiometry including the trabecular bone score.
中轴型脊柱关节炎（axSpA）是一种慢性风湿性疾病，其特征为炎性下背痛和其他几种疾病表现和合并症。2009 年 ASAS 分类标准基于骶髂关节是否存在明确的放射学改变，将经典的强直性脊柱炎或放射学中轴型脊柱关节炎与非放射学中轴型脊柱关节炎区分开来。重要的是，axSpA 患者的背痛可能不仅仅是轴性炎症或新骨形成的原因。还有一些重要的鉴别诊断，如弥漫性特发性骨肥厚和骨硬化症。这篇综述总结了最近关于影像学方法在该领域的表现的出版物，如常规放射摄影、磁共振成像、计算机断层扫描和双能 X 射线吸收法，包括小梁骨评分。
