- What is an MRI Test?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I'm to have a new test called MRI. As with anything medical, and
- unknown, I have become quite worried about this whole deal. Is there
- anything I can do to prepare myself for the test?
-
- ------------------------------------------------------------------------------
-
- ANSWER: Magnetic resonance imaging (MRI) is used to check for possible
- disorders of the brain or spinal cord, or for problems with the lower back,
- heart, chest, pelvis, and other areas. It places you in a strong magnetic
- field, where a series of radio signals will be beamed at the part of your body
- being studied. This will stimulate certain atoms in your own tissue to
- produce radio signals of their own. The resulting signals are translated by
- computer into pictures of that body part.
- Because MRI involves magnets, you will need to remove all jewelry and
- metallic objects, and the test is not for people with pacemakers, surgical
- clips, or other metal objects in their bodies.
- During the test, you will be lying on a table that will slide you inside
- a large metal cylinder. Although you will be able to talk through a
- communications system, tell your doctor if you have ever had claustrophobia or
- anxiety from being a small enclosure.
- Finally, as with x-rays or photos, you need to relax and remain still
- during the test. You won't feel anything, but you'll hear a soft tapping from
- the radio signals. Afterwards, unless your doctor gives you other
- instructions, you'll be able to resume normal activities immediately. It
- would seem that your biggest task at present is to remain calm awaiting a
- test that will cause no physical pain and will assist your physician in
- caring for you.
