I have an artificial hip, and I need an MRI scan of my low back. I know the MRI machine uses a very strong magnet. Will the metal in my artificial hip cause a problem with the MRI?
No. MRI scans are safe even for people with metal implants such as artificial joints, metal plates, and large screws.
The only metal that can cause problems with the MRI is if you have any metal pieces in your head. You need to tell the doctor or the MRI technician if you have any sort of metal clips in your skull from a brain surgery. You may need to get an X-ray of your skull before the scan to double check that there are no pieces of metal near your eyes.
