What is MRI? MRI is Magnetic Resonance Imaging. It allows us to see very clearly inside the human body without the use of X-rays. MRI pictures, called images, help make us the best possible diagnosis.
 
 

How Does It Work? Magnetic resonance produces clear internal body images by using a particular radio frequency to create momentary magnetic changes, and analyzing by computer the signals returned by various tissues.
 
 

Is There Any Risk? There is no risk to the average patient who follows appropriate guidelines regarding metallic items within the body. Before an MRI exam, please tell your physician or the technologist if you have: A pacemaker A metal plate, pin or other metallic implant Ever been wounded during military service An artificial heart valve An intrauterine device (IUD) Aneurysm clips Ever been a metal worker Metallic items within the body may cause discomfort or injury to you when placed in the magnetic field, and may exclude you from the exam. Also be sure to tell us if you are pregnant.

How Long Does An Exam Take? The average MRI scan takes 5 to 15 minutes, with a complete exam running 30 to 60 minutes. During this time, several dozen images may be obtained.

What Can I Expect During The Exam? MRI is very comfortable and easy for the patient. First, the technologist will help you lie down on a cushioned table. When you are comfortably positioned for the exam, the table will move under the magnet. The technologist will then step to the control area, and remain in constant contact with you. As the MRI scan proceeds, you will hear a muffled thumping sound for several minutes at a time. Other than the sound, scanning creates no body sensation. Just relax - or you can even take a nap - but  try to lie as still as possible. Any movement during this time will blur the picture. When scanning is complete, the technologist will return to assist you off the table.

Anything I Can Do For Best Results? Any metallic substance on your person can cause a bright or blank spot on the picture. To help your doctor make the best diagnosis, please do not wear: Hairspray Mascara A hearing aid Any removable dental work Jewelry Eyeglasses In addition, you may find it is easier to lie calmly for several minutes at a time if you avoid drinking coffee or other caffeinated beverages before scanning.
