About Magnetic Resonance Imaging (MRI)

​

An MRI scan uses a magnetic field and energy pulses to create detailed, cross-sectional images of specific organs or structures of the body. It is a tool to help identify a variety of problems with various symptoms or conditions.

 

Before the test

​

Physical preparation for an MRI test is minimal. You should let your doctor know if you have a pacemaker, artificial heart valves or prosthetic limbs, as well as any ear implants, metal implants, pins or are pregnant. If you are on medication in patch form, consult your physician, as some patches have aluminum or foil backing. If you are uncomfortable in small spaces, let your physician know and you may be prescribed a sedative.  An eye (Orbit) X-Ray is required if patients have worked with metal, welding or grinding prior to an MRI examination.

​

On the day of your test remove all jewelry and leave it at home.

​

An MRI will require you to remove your clothing and put on a gown for the examination. It is important to note that if you have any metal jewelry or other metal objects, you should notify the Technologist.

​

During the test

​

You will lie on a table inside of a narrow tunnel and remain as still as possible. Test times can vary between 30-90 minutes and you will be in contact with the technician via intercom throughout to ensure your comfort.

In some cases, a special dye will be injected in your bloodstream to help produce clearer images.

During the exam, you will not experience any pain.

​

After the test

​

Once the test is completed, there are no pain sensations or discomforts that occur normally. You will be able to return to your normal activities when the test is complete. If you were prescribed a sedative for the test, you must arrange for transportation home.
