Tests & Procedures
Gadolinium Contrast
Pronounced: gad-oh-LIN-ee-um
What it is
Gadolinium is a contrast agent sometimes given through an IV during an MRI. It helps highlight areas of active inflammation, which appear bright on the scan. Not every MS MRI uses contrast, and your team decides based on what they are looking for.
Why it matters for you
Knowing what the contrast is for helps you understand why some scans include an IV and some do not. It also explains what your radiologist means by an enhancing lesion.
Questions to ask your doctor
- How many new or enlarging lesions are there?
- Is there any enhancing (active) activity?
- How does this compare to my last scan?
- What areas of the brain or spine are affected?
- Does this change my treatment plan?
