What is MRI? Magnetic Resonance Imaging is a technology that allows your physician to see inside your body without surgery or potentially harmful ionizing radiation. MRI utilizes a strong magnetic field along with radio waves to produce an image. The MRI has no known biological effects. How long will the exam take? The length of the exam depends on the part of the body being imaged and the information your doctor needs. This usually takes from 30 to 60 minutes.

Is there any risk?
Magnetic Resonance Imaging is very safe. There are no health risks associated with the magnetic field or the radio waves used by the machine. However, some special circumstances limit the use of a magnetic field, so it is important for you to tell us if any of the following apply to you or someone accompanying you into the exam room:

Cardiac pacemaker or artificial heart valve Metal plate, pin or other metallic implant Intrauterine device, such as Copper-7 IUD Insulin pump or other infusion pump Aneurysm clips Previous gun wound Inner ear implant Metal fragments in your eye or other parts of your body Permanent (tattoo) eyeliner

How should I prepare for the exam?
No special preparation is needed. You can eat normally and take medication as usual, unless your doctor has given you other instructions. You may find it easier to relax if you avoid drinking coffee or other caffeinated beverages prior to your exam.

Will I need an injection?
In most cases, an MRI exam does not require any injections. In some situations for examining certain areas of the body, the physician may decide to administer a contrast agent to enhance the details of the MR image. All contrast agents are FDA approved and are considered safe. The technologist will discuss this procedure with you and answer any questions you may have.
