Magnetic Resonance Imaging (MRI) is an advanced medical imaging technique that produces cross- sectional images of the body without the use of x-rays. The images are produced using a large magnet, radio frequency waves and a computer system.
Elliot Hospital has state of the art equipment that provides an excellent way to diagnose diseases, infections and inflammatory conditions of the spine, brain, blood vessels, chest, abdomen, pelvis and skeleton.
How does it work? The human body contains an abundant amount of water. The water molecules or hydrogen atoms act as tiny magnets. The MRI magnetic field aligns these tiny magnets. Once a radio wave frequency is applied, the hydrogen atoms release energy that transmits as signal. The MRI test is very noisy due to gradient pulses that determine the location of signals within the body. A powerful antenna collects the signals. The signals are collected and processed by powerful computers to generate detailed images of the body.
