What is Magnetic Resonance Imaging?
Magnetic Resonance Imaging (MRI) is a test that lets your doctor see detailed pictures of the inside of your body. MRI does not use X-Rays. Instead, strong magnets and radio waves work together to form a sharp image. There is no X-Ray radiation and the magnets and radio waves are harmless.
Lake Medical Imaging has both high-field, sort bore MRI and open MRI units in each of our offices located in Leesburg and The Villages.
High-field MRI is a term to describe the comparative magnetic field strength of the magnet itself. High-field magnets are known for high-resolution images and faster exam times. The sort bore of Lake Medical Imaging’s high-field MRI is excellent for patient comfort as well as image quality, as the shorter bore and wider diameter minimize claustrophobic effect.
Of course, many patients prefer the comfort and quiet of an open MRI, which allows patients to look out and talk to imaging personnel. While not all MRI exams can be done on the open unit, consult your physician to see if the ease and comfort of Lake Medical Imaging’s Open MRI is an option for you.
Before Your Exam
MRI uses strong magnets, so you will be asked to remove your watch, jewelry, and other metal objects. Some makeup also contains traces of metal, so you may have to remove that, too. Braces and fillings normally are not a problem. An MRI test takes up to an hour, but give yourself extra time to check in.
Let the Technologist Know:
The magnet used in MRI can cause metal objects in your body to move. You may be asked about any of the following:
- Any previous surgery
- If you have a pacemaker or any other implants
- Metal foreign bodies inside of you, such as surgical clips, stents or fragments from flying metal
Your technologist will also ask you whether:
- You are pregnant or think you may be
- You are claustrophobic (afraid of confined spaces)
During Your Exam
You may be asked to wear a hospital gown. You also may be injected with contrast - a special dye that enhances the image. MRI is done in a long magnet. You'll lie down on a platform that slides into the magnet. Once inside, you'll be able to talk to the technologist. You will be asked to hold very still. You may have to wait a few minutes to make sure the images are of good quality.
For Your Comfort:
- The machine can be noisy, so you may be given earplugs or headphones for music
- The technologist will tell you when you can shift position.
After The Exam
You can get back to your normal activities right away. If you were given contrast, it will pass naturally through your body within a day. Your doctor will let you know when they receive the results.
TEST TIPS
- Follow any instructions you were given to prepare for the test
- Be prepared to remove your watch and other metal objects and makeup before the test
