  • Fillings and permanent retainers do not provide a safety risk and are not general exclusions. However, upper retainers may cause artifacts in ventral frontal regions and therefore may be an exclusion for some studies.
  • Individuals with surgical pins or plates above the neck are excluded. Surgical pins or plates below the neck are exclusions, except when the material is fixed to bone, and considered acceptable by the Reference Manual for Magnetic Resonance Safety. Implants and Devices, 2020 Edition. Almost all recent orthopedic implants are made of materials that are not ferromagnetic and therefore are safe for scanning, and even though some screws are still made of ferromagnetic materials these are firmly screwed into bone. In cases where the material is unknown or deemed unsafe for scanning by the Reference Manual for Magnetic Resonance Safety. Implants and Devices the participant will be excluded.
