What is MRI?
Magnetic Resonance Imaging (MRI) is a diagnostic imaging
technology that uses a strong magnet and radio frequency waves to produce images
of your internal organs.
Do I need an order from my doctor to get an MRI?
Yes, you need an order from your medical provider, similar to
when you need a prescription medication.
Does MRI use x-ray?
No. There is no ionizing (x-ray) radiation used.
Why is this test important?
An MRI allows physicians to see internal organs and structures
from many angles in great detail. It provides needed information quicker, and
often more economically, than exploratory surgeries.
Will the MRI scan be painful?
No. MRI scans are non-invasive and painless. Your physician may
request the use of a contrast agent, however, to better visualize certain
structures. In this case, you will receive a simple IV prior to or during the
exam.
Will I have to change my clothes?
You may need to change your clothes, depending on the body part
we are scanning. However, if you come wearing comfortable clothes with no
zippers or metal, and a sports bra for women, you will most likely not have to
change.
Will I feel anything?
No, but you might hear a loud knocking or buzzing sound at
various intervals during your exam. This is normal, however, and should not
worry you.
Is the machine open at both ends?
Yes. All MRI machines are open at both ends.
Will I be able to keep my head outside of the
MRI machine?
This depends on your height and the body part being scanned. The
area to be scanned is positioned in the center of the magnet, so if your foot is
being scanned, your head will likely be outside the machine. If your head, neck,
or chest is being scanned, however, your head will likely be inside the machine.
Will I be alone during the scan?
You will be alone in the MRI room throughout most of the scan,
but you will be able to contact the technologist at all times via intercom. The
technologist is also able to see you through a large window between the MRI
machine and the control room.
Do I have to hold still throughout the entire
exam?
It is important to remain as still as possible in order to
obtain the best images. Movement during the scan may require the technologist to
repeat certain portions of your exam.
Will I have to drink contrast for my exam?
Contrast is not given orally for MRIs. However, you may be given
contrast by IV depending on what your doctor is looking for.
Will I fit comfortably in the scanner?
There are very few patients who cannot be comfortably
accommodated for an MRI scan.
Is it okay to have an MRI during pregnancy?
Although at this time there are no known risks to mothers or
their fetuses during an MRI, it is not recommended for elective MRI exams.
Is there anyone who cannot have an MRI?
You will be required to complete a health history questionnaire
before having an MRI. Some patients who have metal implants cannot be safely
scanned by MRI. In addition, those with pacemakers, aneurysm clips, and
neurostimulators generally cannot be scanned. Anyone with surgical pins,
shrapnel, plates or metal implants should inform the technologist prior to their
exam.
