Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) is a unique diagnostic tool that allows physicians to evaluate internal body structures without using x-rays or surgery. With this technology physicians can often detect diseases or abnormalities early in their development. This usually means a better outcome for the patient.
MRI uses a strong magnetic field, low frequency radio waves and a computer to produce very clear pictures or images of internal organs and tissues such as the brain, spine and other vital organs.
Our facilities use one of the most patient friendly, high-field MRI scanners available. The shorter length and wider openings (both front and back) of the MRI scanner reduces the possibility of patients experiencing claustrophobia and allows larger patients to be imaged comfortably. At the same time, the high-field feature of the system provides for advanced imaging studies and exceptionally clear images of even very small areas inside the body.
Preparation
Usually there is no specific preparation for a MRI examination. Wear loose comfortable clothing without metal snaps or zippers to your appointment. If necessary you will be asked to change into scrubs or a patient gown.
Before the examination, you will be asked to remove any metal objects such as watches, hair pins, clips or barrettes, jewelry, hearing aids, pages, keys, loose pocket change, bank cards and credit cards. Because of the strong magnetic field, no metal objects are allowed in the scan room. Although a locker is provided for your personal items, we recommend that you leave your valuables at home.
During the Examination
You will lie on a comfortable table that moves you into the proper position for the study. You will be kept informed when you need to lie very still and when it is okay to move. The MRI scanner makes "knocking" sounds of varying loudness while the images are being acquired. You will be given a set of earplugs to help reduce the noise and make you more comfortable. The technologist will be able to see and hear you during the entire examination. The examination takes approximately thirty to forty-five minutes to complete, depending on the type of examination.
If your study requires the use of MRI
intravenous contrast media you will be informed about what to expect
before the procedure is started.
Following the Examination
Once the MRI study is completed, the images are stored on a computer. These images will be studied by board certified radiologists who are specially trained to analyze radiology examinations. A written report of the radiologist's findings will be sent to your physician. Your physician will discuss the results of the examination with you.
After the examination, you may resume your
normal activities.
