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.

An aching back? Well don't sit up straight!

By using a new form of magnetic resonance imaging (MRI), Scottish and Canadian researchers have been able to show that sitting in an upright position places unnecessary strain on the back.

Summary of FDA's approval of silicone breast implants

Two editorials respond to FDA's approval on Friday of the use of silicone breast implants manufactured by Santa Barbara, Calif.-based Mentor and Irvine, Calif.-based Allergan for breast reconstruction and cosmetic breast augmentation.

HRT shows promise in helping visual memory of postmenopausal women

Many women experience declines in their memory during and after menopause, a change thought to be due, in part, to the rapid hormonal changes they weather during that time.

Cause of exercise intolerance in heart failure patients

A new study shows that blood flow to the legs is relatively normal in people with diastolic heart failure, suggesting other potential causes of their inability to do everyday activities, according to researchers at Wake Forest University Baptist Medical Center.

Research sheds light on episodic memory

Memories of events comprise many components--including sights, sounds, smells, and tastes. Somehow the many features of an episodic memory are woven together into a coherent whole, and researchers have had little understanding of how this binding takes place as the memories are processed by the brain's memory center, the hippocampus.

MRI technology breaks new ground in molecular imaging

Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have developed a new technique for magnetic resonance imaging (MRI) that allows for detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI techniques.

Multifunctional polymeric micelles as cancer-targeted, MRI-ultrasensitive drug delivery systems

In an attempt to create a single device that can image and treat tumors simultaneously, researchers at the University of Texas Southwestern Medical Center at Dallas have successfully melded magnetic iron nanoparticles, the anticancer drug doxorubicin, and a polymer tagged with a tumor-targeted molecule into a stable nanoparticle that accumulates inside human tumor cells.

World's first fully digital neuroscience center at Singapore General Hospital

BrainLAB has signed a contract with Singapore Health Services (SingHealth), the largest healthcare group in Singapore, for the establishment of the world's first fully digital neuroscience center at Singapore General Hospital (SGH), one of Asia's leading teaching hospitals.

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.

Researchers identify neurocircuit that controls the brain's response to fear

Results suggest that it may be possible to understand psychiatric disorders, such as anxiety or depression, from the underlying neurophysiology - workings of the brain.

How the brain resolves emotional conflict

Daily life requires that people cope with distracting emotions--from the basketball player who must make a crucial shot amidst a screaming crowd, to a salesman under pressure delivering an important pitch to a client.

MRI tracks survival of pancreatic islets after transplantation

Magnetic resonance imaging (MRI) with an approved contrast agent may provide a practical way of monitoring the survival of transplanted pancreatic islets.

Brain scans show unconscious woman played tennis in her head

Neuroscientists at Britain's Cambridge University say functional magnetic resonance imaging or fMRI brain scans appear to show that a woman in a vegetative state seemed to play tennis in her head despite the fact that she had been unconscious for five months after a motor vehicle accident.
