Both MRI and plain radiography are used to assess sacroiliitis. A weakness of radiography - apart from its inability to detect early disease - is reader variability. On the contrary, experience with MRI is relatively limited by comparison.
This review summarizes recent advances in sacroiliac joint imaging using radiography and MRI in spondyloarthritis.
Observer variation in reading radiographs of sacroiliac joints remains an unresolved issue. In recent years, more studies on MRI in the diagnosis of axial spondyloarthritis have become available. Incorporating structural lesions in the sacroiliac joint and spine and inflammatory lesions in the spine in the definition of a positive MRI are hot topics in research.
MRI和平片均用于评估骶髂关节炎。平片的一个缺点——除了无法检测早期疾病外——是阅片者之间存在差异。相反，相比之下，MRI的应用经验相对有限。
本综述总结了在脊柱关节炎中使用平片和MRI对骶髂关节成像的最新进展。
骶髂关节X线片阅片时的观察者差异仍是一个未解决的问题。近年来，有更多关于MRI在诊断轴性脊柱关节炎方面的研究。将骶髂关节和脊柱的结构病变以及脊柱的炎症病变纳入MRI阳性的定义是研究中的热点话题。
