- 36. Should make sacroiliac and / or spine MRI? • Reading MRI of the spine in addition to the SI increases the number of nonradiographic forms that are ultimately recognized positive MRI compared to reading only SI Sog IH et al. Arthritis Rheum 2008 • It increases quite significantly the number of false positives (mechanical or healthy) • In addition it allows to diagnose other causes of lumbar pain
