Abstract:
OBJECTIVE. Accurate and reproducible MRI assessment of the sacroiliac joint (SIJ) is challenging. Numerous scoring systems have been proposed to facilitate consistent SIJ assessment. The purpose of this article is to evaluate the diagnostic accuracy and reliability of existing MRI-based SIJ scoring systems for the evaluation of spondyloarthropathy. CONCLUSION. Among existing methods, there is fair (grade B) evidence to recommend the Spondyloarthropathy Research Consortium of Canada scoring systems as tools for MRI evaluation of the SIJ. However, limited data on criterion validity limit assessment of scoring system accuracy.
