705Correlation of Radiologic Tests in the Diagnosis of Brucellosis with Osteoarticular Involvement

Eight patients (42.1%) had both sacroiliitis and spondylitis. Pathological involvement was determined in Tc99m bone scintigraphy in only three of 19 patients (15.8%) with sacroiliitis in plain x-rays. One patient with normal bone scintigraphy had bilateral sacroiliitis in MRI. Two patients with normal bone scintigraphy had bilateral spondylitis in MRI. Seven patients had findings of spondylodisciitis in both bone scintigraphy and MRI.
