Magnetic resonance imaging is one of several methods used to reveal the body's internal structures and functions for research and diagnostic purposes. Through the use of a strong magnetic field and radio pulses, MRI technicians can create detailed images of tissues throughout the body. It's especially useful for soft tissues concealed by bones and other dense tissues, in areas such as the brain and joints.
Radiologic technologists perform diagnostic imaging examinations, such as x rays, on patients. MRI technologists operate magnetic resonance imaging (MRI) scanners to create diagnostic images.RI technologists inject patients with contrast dyes so that the images will show up on the scanner. The scanners use magnetic fields in combination with the contrast agent to produce images that a physician can use to diagnose medical problems.
