If you're talking about superconducting magnets, because the boiling point of argon is way too high.
If you're talking about electromagnets (I don't know that any MRI instruments actually use electromagnets, but quite a few research NMR instruments, which use the same principle, do), then it's because argon, as a monatomic gas, has a low heat capacity. The usual coolant for an electromagnet in an NMR spectrometer is the much cheaper and more readily available water, which is both a darn good coolant in its own right, and can be readily re-cooled for another pass through the coils with a swamp cooler.

What is the main purpose of helium?
helium is used to cool superconducting magnets in mri scanners as helium is lighter then air airships use them as gasses
What types of magnets are used in a MRI machine?
Electromagnets
What element cools mri magnets?
liquid helium
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.
What does The force of the MRI magnets pull?
The MRI magnets create a strong magnetic field that aligns the hydrogen atoms in your body. The force of the magnets pulls these aligned atoms, which emit signals used to create detailed images of the inside of your body.
How was science used in creating the MRI?
MRI stands for Magnetic Resonance Imaging therefor magnets are in use of science.
What are 2 jobs that use magnets?
Magnetic resonance imaging (MRI) technician: operates MRI machines that use magnets to produce detailed images of internal body structures for medical diagnosis. Electrician: may use magnets to troubleshoot electrical systems or to create electromagnetic fields for various applications.
How do you demagnetize a credit card?
if you are an mri tech whis the mri machine uses big magnets to see images it can demagnitize a credit card.
What are the uses of magnets?
They are used for: Roller coasters, MRI scans, trains,refrigerators and etc.
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.
Where are permanent magnets located?
Permanent magnets can be found in various everyday items such as refrigerator magnets, electric motors, and speakers. They are also used in many industrial applications like generators and MRI machines.
What uses powerful magnets to examine soft tissue and structure in the brain?
Magnetic Resonance Imaging (MRI) uses powerful magnets to create detailed images of soft tissues and structures in the brain. By applying radio waves in a strong magnetic field, MRI can provide valuable information about the brain's anatomy, function, and possible abnormalities.
