Below is a list of the most frequently asked questions, but please feel free to call our office for any additional questions.
Magnetic Resonance Imaging (MRI) is a
diagnostic imaging technology that uses a strong magnet and radiofrequency
waves to produce pictures or "images" of your internal organs and
structures. Because MRI allows your doctor to see inside your body from any
angle with great clarity, it is giving doctors a wealth of information more
quickly and in many cases, more economically than past tests and exploratory
When you first enter the MRI clinic, you must
let your MRI physician or technologist know if you have a pacemaker, surgical
clips, a prosthesis, metal implants or any other metal objects in your body.
Some implants (e.g., a pacemaker) may be affected by an MRI examination. The
clinic personnel will then determine whether or not you should proceed with
the MRI examination.
Why is this test important? top
MRI allows doctors to see images of your internal organs and structures in great detail from many angles. This gives them information more quickly, and in many cases more economically, than past tests and exploratory surgeries.
No. Since MRI is "non-invasive", the exam is painless. However, your doctor may utilize a contrast agent to better visualize a part of your anatomy. If this is the case, you may receive a simple shot prior to or during the exam.
No, but you will hear a loud knocking or buzzing sound at various intervals throughout your exam. Other than that, you won't feel a thing.
Does the machine use X-rays? top
No. MRI uses a powerful magnet in conjunction with radiofrequency waves to generate images of your internal organs and structures. There is no ionizing (X-Ray) radiation.
There are very few patients who cannot be comfortably accommodated for an MRI exam.
Is the machine open at both ends? top
Yes. All MRI systems are open at both ends but some also have wider openings on the sides.
That will depend on your height and what part of your body is being scanned. The part that is being imaged is in the middle of the magnet. For example, if your ankle is being scanned, your head will be outside of the scanner. If it is your head, neck, or chest is scanned, your head will be inside of the scanner.
Most people have no reaction at all. However, if you have had claustrophobic reactions to enclosed spaces before, please visit one of our Stand-UpTM MRI centers. The Stand-UpTM MRI allows patients to be scanned while in a sitting, standing or bending position.
You will be in contact with a technologist at all times. Even when he or she is not in the MRI room, you will be able to talk to him or her by intercom. The technologist is always able to see you through a large patient viewing window. In some cases a friend or family member may stay in the scan room with you during your exam. Please consult your MRI facility to learn of their policy on this matter.
Does the machine make a lot of noise? top
The magnet makes a knocking sound as images are being taken. In between scans the machine is quiet. Ear plugs should be available to you for your exam and their use will not prevent you from hearing the technologist if he or she speaks to you during the exam. Some MRI facilities also have MR compatible stereo sound systems. When you arrive for your procedure, ask the technologist if a stereo sound system is available.
Do I have to hold still the whole time? top
You do have to remain as still as possible, but the time passes quickly. Moving during the procedure may require repeating parts of the exam so it is best to try to remain as still as possible for the best exam results.
How long will the exam take? top
That will depend on what is being studied, but a typical exam lasts between 30 and 60 minutes. You should always allow extra time in case the exam lasts longer than expected.
Will my insurance cover the cost of the exam? top
Most insurance plans will reimburse the cost of most MRI exams. To find out if your insurance plan covers the specific MRI exam you will be having, contact your personnel office or insurance agent.
Are there things that will prevent me from being scanned? top
Some patients with metal implants cannot be safely scanned in the MR environment. People with pacemakers, aneurysm clips, especially in the brain; and neurostimulators generally cannot be scanned. Anyone with surgical pins, shrapnel, plates or other type of metal implants should notify the technologist. You will be required to provide a health history when you arrive for your exam explaining any metallic implants you may have. A doctor will determine if a particular metal implant is approved to be in an MR environment.
