Magnetic Resonance Imaging (MRI) is a noninvasive medical imaging test that uses a strong magnetic field, radio waves and a specialized computer to produce detailed images of internal soft tissue structures of the human body. The procedure does not use ionizing radiation and is considered to be safe; however, metallic implanted devices within the patient's body may be affected by the magnetic field. When having an MRI, the patient is required to lie on an examination table which then moves him or her into the MRI machine. The machine is open at both ends, and some exams may be performed either head first or feet first. Holding still is important for obtaining the best images since the machine is sensitive to motion. Also, some exams may require an intravenous injection.
- For appointments booked two weeks in advance, the patient should receive a letter in the mail indicating: date, time, location of the appointment, preparation instructions, and a map.
- For appointments booked within two weeks, the patient will be contacted directly by the ordering physician's office, or a medical imaging booking clerk, with the necessary information.
- The patient is responsible for providing his/her physician with the most current address, home and cell phone numbers in order to receive prompt service.
