 ==Overview==
-An option for more accurate (and much earlier) diagnosis of ankylosing spondylitis is [[Computed tomography|tomography]]  of the sacroiliac joints. Joint erosions, [[subchondral]] [[sclerosis]], and bony [[ankylosis]] are better visualized on CT.
 ==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.
