An MRI (magnetic resonance imaging) is a way for doctors to scan and see what is inside the body without having to do surgery or insert cameras into the body. It works similar to an x-ray machine, but instead of using radiation it uses magnets and radio waves.
The patient’s body is surrounded by magnets that scan the body as it passes through a circular tube, and these magnets take high-quality photographs of the inside of your body that doctors can look at and scan afterward.
What they are used for?
MRI’s can scan any body part, including brains, hearts, and the spinal cord without exposing the body to x-ray radiation. This allows for detailed diagnoses, such as looking for torn ligaments, brain injuries, injuries to the spine, and other problems.
These problems can then be treated easily, and will often give the doctors the most information about the condition.
Types of MRI
The traditional MRI scan puts the patient into a large cylinder with headphones for soft music, and they lay there for about 20 minutes while the various magnets scan them. For patients with claustrophobia, being in the enclosed dark tube could cause a trigger for their fears.
Open MRI scanners only have the magnets on the sides and are very open, allowing the patients to see the light of the room, the person performing the test, and the scan is usually quieter than a fully enclosed MRI scan. This is often better for children who must undergo the procedure, as they can see and talk to their parents in the room.
Regardless of what kind of MRI the patient uses, it is often a way to get better and clearer info on a diagnosis without potential side effects from radiation.
