MRI
Exam Overview
Magnetic Resonance Imaging (MRI) is a method of obtaining detailed pictures of internal body structures without the use of radiation or radioactive substances of any kind. This is accomplished by placing the patient in a magnetic field while radio waves are turned on and off. This causes the body to emit its own weak radio signals, which vary according to tissue characteristics. These signals are then picked up by a sensitive antenna and fed to a computer, which produces detailed images of the body for interpretation, by Board Certified radiologists. During the examination you will not feel anything unusual. You will, however, hear a repeated drum-like knocking sound as the scans are recorded. Hearing protection will be provided to those patients who do not wish to listen to music. You can help to produce high quality images by lying still during the examination which breathing normally. The average scan takes 5 to 15 minutes, the complete examination about 30 to 49 minutes, during which time several dozen images will be produced.
