Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

Functional magnetic resonance imaging may be more accurate than the polygraph for lie detection

When people lie, they use different parts of their brains than when they tell the truth, and these brain changes can be measured by functional magnetic resonance imaging (fMRI), according to a study presented today at the annual meeting of the Radiological Society of North America.

Researchers to develop dietary agents to reduce risk of cataracts for astronauts

Astronauts are at increased risk of cataracts because of space radiation. In fact, it is estimated during a long space flight to Mars and back, about one quarter of the crew would become blind because of space radiation-induced cataracts. Other groups which are at increased risk are jet crews, radiation workers and radiation accident cleanup workers.
