MRI & Open MRI
Magnetic Resonance Imaging (MRI) uses a large magnet, radio waves and a computer to produce 2- or 3-dimensional images. MRI scans see right through bone and clearly picture soft tissue so they are especially valuable for helping to diagnose brain and nervous system disorders, cancer and musculoskeletal problems. MRI can also be used to diagnose other conditions and monitor the success of treatment for disease.
Our new GE System is the world's most advanced Open MRI. It is three times as powerful as most other open systems. It combines all the advantages of a traditional high field MRI with the comfort of an open system. For the patient this means faster scanning times without sacrificing imaging quality as often occurs in most other lower field open units. Serving the community for over 18 years, our on-site Board Certified Radiologists have more than 54 years of combined MRI experience.
What should I do to prepare for the exam?
Follow any instructions about eating or taking your usual medications.
Due to the strength of the magnetic field, you must remove all metallic objects before you are scanned. Wear comfortable clothing without metal fasteners. Do not wear jewelry, eye makeup or hair clips.
You will be required to provide a health history when you arrive for your exam including information about any metal implants you may have. Patients with pacemakers and certain metal implants cannot be scanned. Tooth fillings are not affected by the magnetic field, but they may distort images of the facial area or brain, so the technologist should be aware of them.
How much time should I allow?
The length of your exam depends on the type of study being done. A typical exam lasts between 30 and 60 minutes.
What can I expect?
The technologist will help position you on the scanning table. Generally, you will lie on your back. A surface coil may be attached to the part of the body to be scanned. Through the use of an intercom and a mirror the technologist is able to see and hear you throughout the exam. If you become uncomfortable at any point, the technologist will be right there to assist you.
If a contrast agent is needed, you'll be given an injection. A contrast agent improves the quality of certain images. Contrast agents used in MRI can produce allergic reactions, however reactions are rare. Let the technologist know if you have any allergies or feel sick or experience any discomfort.
As the scan begins, the scanning table will slide into the scanner. During your MRI exam you'll probably hear a knocking or buzzing sound that occurs as the images are being taken. You'll be provided with ear plugs to wear during the scan or an audio headset may be available to minimize the noise. You will be asked not to move during the actual imaging process, but between sequences some movement is allowed.
After the scan is complete you may resume your normal activity and eating habits.
