What happens if you have an MRI with metal in your body?
The presence of metal can be a serious problem in MRI, because (1) Magnetic metals can experience a force in the scanner, (2) Long wires (such as in pacemakers) can result in induced currents and heating from the RF magnetic field and (3) Metals cause the static (B0) magnetic field to be inhomogeneous, causing severe …
Can you have an MRI with metal implants?
In most cases, an MRI exam is safe for patients with metal implants, except for a few types.
