The fragment is the size of a pea.

No you can't. The magnetic field is so strong that even if your head were outside of the mri it would still dislodge the fragment.

Yes. The MRI literally does use magnets but the focus of the magnetic field is quite small. Thus an MRI of the head will have no influence on a lead fragment in the brain. Good luck with your scan.

No way will a responsible MRI company give you a scan. The magnetic field will fill the entire shielded room. I have been given many presentations by MRI companies and this is usually discussed. It also turns out that the magnetic field is so intense it can affect non-ferrous metals. Bullets also are made from re-cycled car batteries and are a mix of various alloys so you don't know what metals are in you head.

I do not think a MRI can be performed. Though it probably would not affect you, the institution will not take the risk. Ask for a multiple slice CT scan and perhaps that test will help you with your problem.

lead is not magnetic metal, so a mri would have no affect on it at all.
