Magnetic resonance imaging (MRI) makes internal body structures visible. However, before humans or animals are put into the "tube," they are injected with a contrast agent to make visibility possible ...

Magnetic resonance imaging (MRI) is a technique using magnets, radio waves, and a computer that produces images of soft tissues in the body, like muscles and organs. Unlike some other imaging tests, ...
