I have a vns vagus nerve stimulator for epilepsy, how safe is a mri?

Vagal nerve MRI: Vagal nerve stimulator patients can have MRI evaluation, but need to have the type of stimulator and MRI known so safety measures can be reviewed. The two main possible problems are stimulator movement in the magnetic field and heat build up in the stimulator during the procedure. Both of these risks are low with the recent models of stimulators.

MRI is restricted: Mri can be performed in patients with vns, but only under certain conditions. The type of MRI machine and location on the body being scanned are important. Also, if MRI is being performed, the vns will need to be turned off prior to the study and turned back on after the study is complete. Your neurologist and the radiologist at the MRI center should be able to provide more details.
