I have multiple sclerosis and have had 22 mri's with gadolinum in the last 10 years. Does this put me risk of cancer?

7 doctors agree

In brief: Probably not

Gadolinium is a paramagnetic substance that enhances MRI images when given intravenously.
It is not clearly associated with any cancers. It is largely inert in humans and completely eliminated from the system in a fairly short period of time, though in patients with kidney failure there are rare cases of kidney damage from repeated injection.

As for the MRI itself, the procedure does NOT use radiation, so there is no risk of cancer from the MRI itself. CT, however, does cause increased risk of cancer
1 doctor agrees

In brief: No additional risk

No. The MRI posses no cancer risk as there is no ionizing radiation associated with the scan.
The gadolinium is a potential nephrotoxin(kidney) in patients with impaired renal function. Typically bun/creatinine levels are checked prior to the administration of gadolinium.

In brief: NO radiation

MRI's use magnets, not radiation.
No known risk of cancer.
