How does an MRI work?
Before the MRI exam, your Cape Radiology Group technologist will discuss your medical history with you and answer any questions you might have. You'll be asked to change into a gown and go to the bathroom to ensure your comfort during the exam. When using MRI, certain items will need to be removed due to the magnetic field, including jewelry, glasses, hearing aids, clothing with zippers, nonpermanent dentures, credit cards, some cosmetics and metal objects, such as hairpins or barrettes. The technologist will position you on the scanning table and make you as comfortable as possible. We also offer earphones and music for your relaxation.

While on the scanning table, a large magnet creates a magnetic field that causes protons inside the atoms in your body to line up together and spin in the same direction. As the radio frequency is beamed into the magnetic field, it forces the protons to move out of alignment. When the signal stops, the protons move back into place and release energy. At this point, a receiver coil measures the disturbed protons and provides data about the condition of the tissue in which the protons lie. A computer is then used to process the signals and construct an image on a viewing screen.

During the scanning process, it is important that you relax and lie as still as possible so the images do not blur. During the actual operation of the equipment, you will hear intermittent thumping and humming sounds that are quite normal during the scanning process. In some instances, a contrast agent may be required to enhance the quality of certain images, in which case you'll be given an injection during the scan. The procedure generally takes 60 to 90 minutes, depending on the type of exam you are having.

Your examination will be interpreted by a radiologist, and the report will be sent to your referring physician. You should make arrangements with your physician on how you will receive your results (such as follow-up appointment or calling the physician's office).
