Are Sacroiliac Joint MRIs Accurate in Routine Clinical Practice?

Conclusion

This large European real-world study overall showed moderate agreement between local and central reads, but also demonstrated that local radiologists tend to overestimate inflammatory lesions and underestimate structural lesions in routine care sacroiliac joint MRIs. This speaks to a need for further training of local radiologists to optimize the diagnostic accuracy of MRI in spondyloarthritis.
