Question

Quizplus · Accepted Answer

X-ray imaging is the most important test for diagnosing ankylosing spondylitis as it can reveal characteristic changes in the spine and sacroiliac joints. Bone biopsy and electromyography are not typically used in the diagnosis of ankylosing spondylitis, while radionuclide bone scans may be useful for detecting early changes but are not as sensitive as x-ray imaging.
