Understanding Magnetic Resonance Imaging
WHAT IS AN MRI?
A magnetic resonance imaging (MRI) test uses radio waves and a magnetic field to understand what is going on inside the body. Because the MRI emits radio waves instead of X-rays or other radiation, it is one of the safest techniques for doctors to use to observe many conditions.
HOW DOES IT WORK?
Magnetic resonance imaging works by using a magnetic field to measure the resonance of radio waves inside the body and taking images of this resonance. It works by sending out radio waves to the body, which then react with hydrogen atoms found in the water inside your body. These hydrogen atoms return a modified radio wave signal, and the machine reads and makes an image of this signal. By compiling all of these images, doctors are able to discover what’s going on inside the body.
