Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.

Remote-control software that enables off-site MRI imaging via the Internet

UCLA radiologists and Siemens Medical Solutions have developed remote-control software that enables an off-site imaging expert to operate a magnetic resonance imaging (MRI) machine via the Internet.

Parkinson's disease affects more than just motor control

Although Parkinson's disease is most commonly viewed as a "movement disorder," scientists have found that the disease also causes widespread abnormalities in touch and vision - effects that have now been verified using functional magnetic resonance imaging (fMRI) of the brain.

Researchers find areas in the brain that indicate bilingualism

The finding sheds new light on decades of debate about how the human brain's language centers may actually be enhanced when faced with two or more languages as opposed to only one.

Cocaine addicts have an altered perception of reward

People addicted to cocaine have an impaired ability to perceive rewards and exercise control due to disruptions in the brain's reward and control circuits, according to a series of brain-mapping studies and neuropsychological tests conducted at the U.S. Department of Energy's Brookhaven National Laboratory.

Anticipation plays a powerful role in human memory

Psychologists have long known that memories of disturbing emotional events - such as an act of violence or the unexpected death of a loved one - are more vivid and deeply imprinted in the brain than mundane recollections of everyday matters.
