An MRI produces images through the use of magnetic fields and radio frequency pulses. It does not use ionizing radiation. MRI is more sensitive in evaluating soft tissue compared to other imaging techniques, and produces detailed images of the brain, internal organs, bones, joints and other structures. The high level of accuracy and low risk of the procedure makes MRI a valuable tool. Under certain circumstances, a contrast agent may be administered orally and/or intravenously to enhance the image.
As MRI uses magnetic fields, some metals will interfere with the study, and may not be performed if you have a pacemaker, metal clip implants, or cochlear implants. We’ll ask you about past surgeries and injuries to ensure the MRI may be safely administered. Please let our staff know of any metal you have on or in your body, if you are or think you may be pregnant, or if you have an implant. Most MRI exams do not require special dietary considerations, but if there are any, you will be notified prior. We request you wear comfortable, athletic-style clothes, free of metal or other objects (zippers, buttons, etc), and remove any personal items containing metal. An MRI takes about an hour, and it’s important to stay as still as possible. You may be asked to hold your breath at times.
