MR images are formed by the computer processing of signals that are emitted by body tissue. These signals are generated using a safe magnetic field in combination with radio waves of a specific frequency. Different tissue characteristics are revealed through this process and translated into different contrast levels on the image. The procedure typically will last anywhere from 15-30 minutes, depending on the type of information required by your physician. All that is required of you is to be as still as possible during the exam. In fact, some patients fall asleep during their MRI exam. You will be readily visible by the technologist at all times. For your convenience, an intercom system is built into the magnet so that if you should need anything at all, the technologist will be right there. In certain instance, a contrast agent may be administered to enhance the study. There are no extra precautions should the doctor require this. Consult the doctor or technologist to answer any questions you may have.
What Should I Expect During a MRI?
- You may be asked to change into scrubs and escorted to the MRI room.
- A MRI technologist will assist you on to the padded exam table and position you for the procedure.
- During the procedure, you will need to lie as still as possible; movement can cause blurred images requiring the MRI technologist to repeat part of the procedure.
- You will hear knocking sounds during the procedure. Earplugs, headphones, or music will be provided for your comfort.
- The MRI technologist will be in constant communication with you during the procedure using a two-way microphone system.
- For your comfort, blankets and/or pillows will be provided upon request. The MRI exam room is typically cool in order to ensure that the computer system operates properly.
- Some patients may require an intravenous injection of a contrast material to enhance the visibility of certain tissues or blood vessels.
- Our goal is to provide you with a pleasant and comfortable MRI procedure. If you are uncomfortable in any way, please inform your MRI technologist.
