NO!! A Cat scan is NOT a type of magnetic resonance imaging. A CAT SCAN - Computer Aided Tomography uses X-rays to create a 3D image of tissue density . An MRI Magnetic Resonance Imaging uses a magnetic field and radio frequencies to image tissue chemistry. Totally different imaging procedures.
I happen to be an authority on the subject.
Yes yes
@Maglatron was trying to explain his delivery of a joke the timing of it...
He's a brit so we will just laugh and tell him he's funny...
We both know MRIs employ powerful magnets which produce a strong magnetic field that forces
protons in the body to align with that field. When a radiofrequency current is pulsed through the human body, the protons are stimulated,and spin out of equilibrium,straining against the pull of the magnetic field.
When the radiofrequency field is turned off,the MRI sensors are able to detect
the energy released as the protons realign with the magnetic field.
The time it takes for the protons
to realign with the magnetic field,as well as the amount of energy released,
changes depending on the environment & the chemical nature of the molecules.
The magnetic field extends beyond the machine and exerts very powerful forces on objects of iron, some steels, ferrous materia,l magnetic coercivity , magnetic permeability, & other magnetizable objects; it is strong enough to fling a wheelchair across the room.
