TMS treatment should not be used by anyone with a seizure disorder or high seizure risk. TMS should also not be used by anyone who has magnetic-sensitive metal in their head within 10 cm or 4 inches from the TMS coil, that cannot be removed. This would include patients with any unremovable metal, implanted in or around the head, including metal plates, aneurysm coils, cochlear implants, ocular implants, brain stimulation devices, stents or bullet fragments.
