I am not as sure what having a replacement hip or other joint or large metal pins or screws in one's body will do in an MRI scan; there could possibly be some concern there that would limit its usefulness. Of course, we who have had dental cavities have plenty of metal in our teeth and are able to go through MRIs without a problem.
I bet it would wreck your laptop and might even cause problems with pacemakers,


MRI is not an option. The magnet is thousands of times stronger than he earths magnetic field. The gold and silver and mercury fillings in your teeth are not a problem, only iron/steel as a previous writer said.

I worked near one once, you leave your steel tools and your wallet in your car. The magnetic field will erase your credit card stripe, which means goodbye hard drive and floppies in your laptop. Everyone has 100% backup at home, right?

Older implants were stainless steel, many now are titanium. But stainless steel screws are common. Stainless steel is slightly magnetic. Been in a war? Those steel scraps are coming out! The stainless wire cage around your artificial heart valve? Ouch. Your pacemaker? Toast.

A hospital has special all aluminum gurneys to roll patients to the MRI. The new orderly who forgets and rolls a patient up on a steel gurney will lose his load and the hospital will win a big lawsuit from the patient who got sucked into the magnet head first.

Prohibited Items
During an MRI scan, the following items could interfere with the procedure or even become unsafe. Therefore, they are not allowed in the MRI scanning area. You may leave them at home, with family or friends, or in a secure locker which we will provide for you.
• Keys • Metal zippers • Coins
• Watches • Metal buttons • Belt buckles
• Hearing aids • Wallet/money clips • Safety pins
• Jewelry • Pocket knife • Removable dental work
• Glasses • Pens/pencils • Hairpins/barrettes
• Bras with hooks/ underwires • Credit/bank cards (magnetic strip)

Before Your Test Begins
Since a strong magnetic field is always present within the scan room, not all patients should undergo an MRI scan. Please let your physician or the MRI technologist know if you have any of the following:
• Cardiac pacemaker • Shunts • Metal mesh
• Aneurysm clips • Insulin pump • Shrapnel/bullets
• Joint replacement • Electrodes • Orbital prosthesis
• Hearing aid • Cochlear prosthesis • Dentures
• Heart valve prosthesis • IUD • Bone/joint prosthesis
• Neurostimulators (TENS-Unit) • Penile implant

If TSA did use a MRI, all the above would get bypassed.
