Magnetic Resonance Imaging
Some common questions about MRI examination and procedures include the following. Please click on the question to read the answer.
1) What is an MRI scan?
Developed in the 1980’s, Magnetic Resonance
Imaging utilizes computers & magnetic fields to
provide safe and non-invasive images of the human
anatomy. Unlike X-ray & CT scans, MRI uses
no radiation.
MRI uses powerful, superconducting magnets which
generate a magnetic field 30,000 to 60,000 times
stronger than that of the Earth. The strength of the
MRI is measured in units called Tesla.
1 Tesla = 20,000 X earth’s magnetic pull
2) Is it safe?
MRI is a safe and effective diagnostic precedure. It does not use ionizing radiation like an X-ray. Like many other medical imaging
technologies, MRI has been cleared by the U.S. Food and Drug administration.
3) What do I need to tell my physician or MRI technologist?
Patients with a heart pacemaker, metal implants, or metal
chips or clips in or around the eyes cannot be scanned with
MRI because of the effect of the magnet on these objects.
4) How do I prepare for an MRI?
All metallic objects on the body are removed prior to
obtaining a MRI scan. Occasionally, patients will be given
sedative medication* to decrease anxiety and relax the
patient during the scan.
5) Do I need an injection for my MRI?
Occasionally, patients require an injection of contrast media
intravenously to enhance the images.
6) Can I move while I am getting an MRI?
It is important to remain as still as possible during the MRI.
However, if you should become uncomfortable or need to
speak, the intercom and window arrangement in the room
assures the MRI staff can see and hear you during your study.
7) What do I need to do to prepare?
8) What does NPO mean?
NPO is a Latin abbreviation for "nothing by mouth." and refers to the recommendations regarding eating
and drinking prior to an examination. Please refer to information about
patient preparation
9) How long will it take to get my results?
Results are typically available for your physician to review within 24 - 48 hours after your exam.
