Magnetic Resonance Imaging (MRI) is a diagnostic imaging procedure that uses a combination of a powerful magnet, radio waves, and computer technology to produce detailed images of structures and organs within the body.
Some MRI machines look like narrow tunnels, while others are more open. The MRI machine creates a strong magnetic field around the patient. The magnetic field along with radio waves alters the hydrogen atoms' natural alignment in the body. As the atoms return to their natural alignment radio signals are given off. These signals are read by a receive coil (radio antenna) and sent to a computer to be transformed into images. MRI images are displayed on a computer viewing monitor.
Some MRI exams require the use of contrast. MRI contrast is injected in an IV line to produce more detailed images of certain organs or structures. Unlike x-ray or CT scan contrast, MRI contrast is not iodine. Most MRI exams do not require you to fast for the procedure. Please remove make-up, nail polish, piercings before coming to the appointment.
MRI is not for everyone. Patients with pacemakers, aneurysm clips, bullets or shrapnel, or other metallic materials may not be allowed to have an MRI procedure. Certain metallic materials could become dislodged when placed in the strong magnetic field.
Patients with claustrophobia may require your physician to provide sedation for you to undergo an MRI.
You should consult your doctor if you have questions about your MRI exam.
