No. Put simply, an MRI scanner utilised radio waves and a magnetic field. Without a magnet, there is no magnetic resonance imaging (MRI).
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.
No u can't. An MRI is done by a giant magnet.
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.

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.
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.
The Magnet
A 1 Tesla magnet in MRI technology creates a strong magnetic field that aligns the hydrogen atoms in the body. When radio waves are applied, the atoms emit signals that are used to create detailed images of the internal structures of the body.
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.
MRI systems are significantly stronger than refrigerator magnets, with MRI systems typically having magnetic fields thousands of times stronger than refrigerator magnets.
To keep the magnet cool. MRI machines need to generate a very strong magnetic field. They do this using superconducting electromagnet- basically a large coil of wire with a large current passing through it. The magnet must be kept very cold, almost at absolute zero, or it will not superconduct.
