Do I have to do anything special if I have metal in my body?

According to TSA, if you have implants or internal medical devices, “Inform the TSA officer that you have an artificial knee, hip, other metal implant or a pacemaker, defibrillator or other internal medical device. You may provide the officer with the TSA notification card or other medical documentation to describe your condition.

Advanced imaging technology can facilitate your screening and reduces the likelihood of a pat-down. You should not be screened by a walk-through metal detector if you have an internal medical device such as a pacemaker. Consult with your physician prior to flying.

If you choose to not be screened through the advanced imaging technology or you alarm the walk-through metal detector, you will undergo a pat-down screening instead.
