Bone Marrow Edema on Magnetic Resonance Imaging (MRI) of the Sacroiliac Joints Is Associated with Development of Fatty Lesions on MRI over a 1-year Interval in Patients with Early Inflammatory Low Back Pain: A 2-year Followup Study

Objective. To assess whether bone marrow edema (BME) detected on magnetic resonance imaging (MRI) of the sacroiliac joints (MRI-SIJ) is associated with development of structural changes on both MRI and pelvic radiographs in patients with early inflammatory back pain (IBP). Methods. Patients with IB
