Should radiologists image and report sacroiliac joints in patients referred for examination of the lumbar spine? Original Research Article

It is routine to image the sacroiliac joints (SIJs) in patients referred for radiographic examination of the lumbar spine but there were only two consistent with ankylosing spondylitis in a review of 392 radiographic reports of lumbar spine examinations. A more sensible policy would be to only image and report on the SIJs if the clinical history were indicative of ankylosing spondylosis.
