MRI
Magnetic Resonance Imaging (MRI) uses a magnetic field, radio frequency pulses, and computers to obtain images of the internal structures of your body. An MRI can produce detailed images of virtually all internal structures - bone, organs, soft tissue, and blood vessels. Since the MRI involves a strong magnetic field, you'll be asked to remove any metal objects, including watches and other jewelry, eyeglasses, and any removable metal dental work. For some procedures, a contrast material may be injected intravenously.

An MRI unit is a large cylinder with a movable table that slides into a tube at the center of the unit. The technologist will position you on the table and ask you to remain as still as possible. Pillows and straps may be used to help you comfortably maintain the proper position. The table will be moved into the tube for the imaging process. You may hear tapping sounds as the images are taken. The technologist may ask you to hold your breath briefly to ensure the clarity of the images. You may also feel a slight warmth on the part of the body being imaged as the images are being recorded. This is normal and harmless. Depending on the type of exam and the type of equipment used, the process may take 15 to 45 minutes.
