Learning that you better undergo a magnetic resonance imaging (MRI) test can be intimidating.
What Is a Magnetic Resonance Imaging (MRI) Scan?
Magnetic resonance imaging (MRI)is a non-invasive radiographic study used to diagnose medical problems.

Much like anx-ray, the technique allows the visualization of structures that would otherwise be inaccessible without surgery.
The pulse of the magnet affects the water molecules of the body and the resulting changes can produce images.
MRI is especially helpful in specific areas of the body, including the brain.
As part of this, a careful assessment of your history will occur.
This typically involves a checklist to ensure that the MRI can be performed safely.
You may lie with a neck and head brace, padding, or sheet to make you more comfortable.
There may be a few belts put in place to help you remain in place.
In some cases, a helmet-like structure called a brain receiver coil may be placed around the head.
As the test can be noisy, earplugs, headphones, or other hearing protection devices may be used.
In some cases, you may be able to listen to music.
The examination table will move in and out of a large tube during the study.
A mirror may be put into place above your eyes so that you might see out of the machine.
Once you are initially put in position, the technologist will leave the room.
You will be able to communicate with them during the study.
They will be able to monitor you from nearby and can return quickly should the need arise.
The MRI itself will typically consist of a series of imaging sequences.
This may require that you lie still for seconds or minutes at a time.
The technologist will prompt you over a two-way intercom as the test proceeds.
How to Cope With the MRI Experience
There are some common concerns related to having an MRI.
The biggest concern most people have is feelingclaustrophobic.
Although the use of mirrors may help, some people may need medications to help them feel more relaxed.
The use of open-ended (or open-sided) MRI machines can also alleviate this feeling.
If you are significantly obese, the MRI machine may be too small to fit you inside.
The size restriction varies based on the machine, and alternatives can typically be found.
If you are concerned about tolerating the test, don’t simply refuse to do it.
