The radiographic diagnosis of sacroiliitis. A comparison of different views with computed tomograms of the sacroiliac joint

Arthritis Rheum. 1983 Jun;26(6):760-3. doi: 10.1002/art.1780260609.


Conventional radiography is the standard method of objectively identifying sacroiliitis. Single views of the sacroiliac joints can be unequivocally interpreted in 70-80% of patients with low back pain. A series of views usually correctly resolves the ambiguity in the remaining 20-30% of patients (67% correct). Computed tomography will be helpful in the few patients in whom a series of views produces equivocal interpretation.
