Reddit reviews Ankylosing Spondylitis (Oxford American Respiratory Library) (Oxford American Rheumatology Library)

I'm not a doctor, so I'm not disagreeing with you, but my little booklet about AS says that sacroilitis revealed by STIR MRI has both sensitivity and specificity of 90%. It's also from 2009.

I just recall my rheumatologist that glanced at my MRI evaulation for no more than 5 seconds (before asking me about anything else), and said "It's Bechterew's. 100% certain." :-)

By the way, I paid full price (no insurance involved) for my MRI, but it was not a contrast MRI.
