Ankylosing Spondylitis Sacroiliitis CT changes MRI Online Radiology Course
Another three quick images with some basic key points from our online spine MRI courses.
Here we look at the changes seen on CT at the Sacro Iliac Joint.
Bony erosions and sclerosis are the common findings on CT. Look for irregularity of the margins at the SIJ with sclerosis deep to the erosions. The sclerosis represents areas of previous inflammation that have resolved and sclerosed.
Fusion of the SIJ is a late finding. Initial chondral destruction followed by progressive ossification.
As a late stage finding ossification of the capsule can occur. Look for linear ossification at the superior > inferior margins.
We go into more detail with videos, dicoms, quizzes and the ability for you to ask questions to clear doubts about Ankylosing Spondylitis, Spondyloarthritis SpA and Arthritis Imaging in our Guided MRI Spine Spondyloarthritis and Arthritis Mini Fellowship.
