Overview
CT
- May be useful in selected patients with normal or equivocal findings on sacroiliac joint radiographs
- Joint erosions, subchondral sclerosis, and bony ankylosis are better visualized on CT
- Some normal variants of the SI joints may mimic features of sacroiliitis
- CT supplements scintigraphy in evaluated areas of increased uptake
- Multidetector CT is superior to radiographs and MRI in demonstrating injuries
- MDCT is imaging modality of choice in patients with advanced ankylosing spondylitis for whom there is suspicion of cervical spine fracture
