MRI Scan
WHAT IS MAGNETIC RESONANCE IMAGING?
Magnetic Resonance Imaging (MRI) is an advanced imaging method that produces images of the body without surgery or X-rays. MRI uses a large magnet, radio waves, and a computer to produce these images.
WHAT SHOULD I EXPECT?
The MRI exam can be one of the easiest and most comfortable exams you experience. The technologist will ask you to lie on a cushioned table that will move into the tube-shaped scanner after you have been comfortably positioned. Your technologist will watch you through an observation window and will be able to communicate with you at all times. The scanner makes tapping noises that change with the various imaging sequences. Remaining still during these noises is very important in order to obtain clear images.
When scanning is complete, the technologist will return to help you from the table. You may eat normal meals unless other tests are scheduled. Your exam will take about 30 to 60 minutes, after which you will be able to return to your normal activities.
WHAT DO I NEED TO DO TO PREPARE FOR AN MRI?
There are no special diets or medication needed before an MRI. However, because MRI uses magnets, nothing metallic is allowed in the room. This includes:
-
Jewelry
-
Battery-operated objects, such as hearing aids and watches
-
Credit cards, bank cards, ATM cards or anything with a metallic strip
-
Hairpins
-
Metal zippers
-
Removable dental work
Not only may these items be damaged, but they also can distort the images. Wearing clothing without metal, such as a sweatsuit, is ideal. Make sure you tell your technologist if you have a pacemaker, hip replacement or other metal in your body. Although the test is painless, some people experience a claustrophobic reaction. You can have a friend or family member accompany you, or bring your favorite music to help you relax. (Sorry, no children are permitted.)
WHAT WILL THE MRI BE LIKE?
Once you’ve arrived at MedWise, you will be asked to change into a patient gown and remove all jewelry. You can request a pillow or blanket in order to make yourself more comfortable during the test.
During the test, you will be asked to stay as still as possible, as excessive movement can blur the image. Your technologist will be observing you the entire time and can speak with you via an intercom inside the machine.
Depending on the test, you may be injected with a contrasting agent. Contrast agents are simply dyes that allow the radiologist to see certain areas or organs more clearly.
WHAT HAPPENS AFTER THE TEST?
You can immediately resume normal activities unless you received a sedative. If you are sedated, you must be accompanied by a driver to escort you home.
WHAT IF I NEED A CONTRAST INJECTION?
MRI scans are painless, but some exams require an injection of a contrast agent to make some abnormalities easier to see. MRI contrast is an organically bound gadolinium material that is extremely safe and typically has no side effects. However, there is always the potential for allergic reaction. Be sure to tell your technologist if you've had a reaction to MRI contrast or if you are particularly sensitive to medications.
HOW DO I GET RESULTS?
After your study is over, the images will be evaluated by one of our board-certified radiologists with expertise in MRI imaging. A final report will be sent to your doctor, who can then discuss the results with you in detail.
Should you have any questions regarding your MRI scan, we will be happy to discuss them with you.
