What is CECT SI Joints?

Contrast Enhanced Computerized Tomography(CECT) Scan of the SI joints (sacro-iliac joints) is a diagnostic procedure in which a contrast material is injected and the rotating beams of X-rays are used to create cross sectional images of the SI joint. This joint is formed between the triangular bone at the lower end of the spine and the right and left iliac bones of the pelvis, which can then be used to create a three dimensional image to detect and diagnose disorders of this joint.
