Gadolinium is a commonly used contrast agent for MRI imaging of the spine. It can help differentiate between recurrent disc herniation and scar formation by highlighting areas of inflammation and enhancement, which are more commonly seen with recurrent disc herniation. Technetium is used in bone scans, iodine is used in CT scans, and Pantopaque is a type of oil-based contrast agent used in myelography, but not in MRI imaging.
