What Is MRI?
Magnetic Resonance Imaging (MRI) is a sophisticated and highly accurate imaging technique used to diagnose diseases of the brain, spine, skeleton, chest, abdomen, pelvis and blood vessels.
MRI is a completely safe, non-invasive and painless diagnostic procedure. With a large magnet, radio waves and a computer, MRI produces detailed cross-sectional pictures of your internal organs and structures without using ionizing radiation.
During your MRI exam, you will lie on a table and a "coil" will be placed on or under your body. This coil helps direct the magnetic energy to a specific body part. The table will move you into a tunnel-like opening. The amount of your body that is actually in the tunnel will depend upon the body part being examined.
Very simply, the tunnel-like opening contains a magnet that helps to create images of your body. These images go to a computer and show the organs, bones, muscles, arteries, etc. Your doctor will use those images to make an accurate diagnosis and plan your treatment as necessary.
Additional information about what you can expect is defined below. If you have any additional questions about your MRI exam, please contact your physician or a member of our staff.
What Can I Expect?
An MRI exam generally takes between 30 minutes and an hour. The length of your exam will depend on the type of study your doctor has ordered.
We want to ensure complete comfort during your exam. The technologist will help you lie on an automatic, cushioned scanning table. You'll rest on your back with your head in a cushioned headrest.
Once you are completely comfortable, the technologist will position a device, called a "coil," over or under you. The coil helps produce the clearest picture of the area it covers.
When you are properly positioned, the table will slide into the opening of the machine and the exam will begin. It's important that you remain as still as possible throughout the exam. You won't feel a thing, but you will hear a muted thumping or knocking sound for several minutes at a time. This is completely normal.
If you become uncomfortable or have questions at any time, you'll be able to communicate with the technologist through a built-in intercom. When the exam is complete, the technologist will help you off the table and you'll collect your personal belongings.
Will I Need An Injection?
In some cases, your doctor may order a contrast agent to enhance the images. The agents, which are completely safe and FDA-approved, are injected into a vein in your arm.
How Do I Prepare?
Metallic objects limit the accuracy of MRI, and the magnetic field can interfere with some surgically implanted devices. Also there are other safety concerns. If any of the following apply to you, tell your doctor:
