MRI Sacro-Iliac (SI) Joint with Contrast

A Magnetic Resonance Imaging (MRI) SI (Sacroiliac) Joint with Contrast creates a picture of the joint located between the ilium and sacrum bones of the pelvis and surrounding soft tissues. The contrast helps in increasing the visibility of the internal organs and hence improves the sensitivity and diagnostic accuracy of the MRI scan.

This test is prescribed by the doctor to find out subchondral sclerosis (thickening of the bone in joints) and sacroiliitis (inflammatory condition of the connection point of pelvis and lower spine).
