What else can I help you with?
Will a MRI work without a magnet?
No. Put simply, an MRI scanner utilised radio waves and a magnetic field. Without a magnet, there is no magnetic resonance imaging (MRI).
Can you have an MRI with a steel plate in your head?
No u can't. An MRI is done by a giant magnet.
Is it possible to have a MRI body scan with a defibrillator fitted?
no it is not possible to have an MRI scan because the dfibrillator is dirupted by magnets and that is what an MRI is, a giant magnet.
How much stronger is a MRI magnet compared to refrigerator magnet?
20000
Will my head be out of the MRI for an MRI of my tibia?
If the MRI technologist positions you with your leg going into the magnet (the MRI machine) then your head would be out of it. Call the facility where you are scheduled to have the MRI and ask to speak with the MRI technologist and they can fully explain to you exactly how you will be positioned.
How is the MRI used to study cross sections of the brain?
The Magnet
CAN YOU HAVE A MRI WITH A COCHLEAR IMPLANT?
Cochlear implants have magnets in them which interfere with the MRI process. The magnet from the implant will require removal before the MRI exam, but can be replaced after the scan. There are cochlear implants nowadays which can undergo medical procedures such as MRI's without removing anything.
When Liquid helium is cut off by a power loss what happens to a MRI magnet?
When power is lost, the liquid helium in an MRI magnet will begin to warm up and boil off. This can lead to a rapid increase in pressure inside the magnet, causing a potential risk of an explosion if not handled properly. The magnet will also lose its superconducting properties, rendering the MRI machine unusable until it is refilled with liquid helium and re-cooled.
How much stronger are MRI systems compared to a refrigerator magnet?
MRI systems are significantly stronger than refrigerator magnets, with MRI systems typically having magnetic fields thousands of times stronger than refrigerator magnets.
What do you mean by quench in relation to MRI scanners?
Most of the MRI scanners today use superconducting magnets that need liquid helium to keep them cold enough for proper function. A malfunction may, however, cause the helium to convert to gas and rapidly escape the cryogenic chamber that effectively demagnetizes the main MRI magnet. When this happens, a MRI magnet is said to have "quenched". This not only incurs expensive repairs to the equipment but the rapidly escaping helium in the close confines of a MRI suite may also cause asphyxiation injury to any person present there. Fortunately this catastrophe is extremely rare and has been virtually eliminated in the newer equipment through improved design.

How does an MRI work and what does an MRI Tech do?
The magnetic resonance imaging system uses a superconducting magnet to interpretate the behavior of the particles and convert to image using a computer. The technician operates the machine.
