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

Gadolinium-based MRI contrast agents deposit in the brain

The International Society for Magnetic Resonance in Medicine has provided new guidance in the use of contrast agents during MRI scans. Emerging research suggests gadolinium-based contrast agents, injected in a patient's veins to brighten tissues in MRI images, accumulate in the brain.

Scientists creating blood test to identify breast cancer patients at risk for brain metastasis

Houston Methodist cancer researchers are now closer to creating a blood test that can identify breast cancer patients who are at increased risk for developing brain metastasis, and also monitor disease progression and response to therapy in real time.

UAMS scientists awarded $422,610 NSF grant to study regulation of emotion

A team of University of Arkansas for Medical Sciences research scientists recently received a $422,610 grant from the National Science Foundation to study the mechanisms of control of emotional responses of men and women using functional magnetic resonance imaging (fMRI).

Study reveals effects of drowning-induced brain injury in children

A new study indicates that children who develop brain injury due to non-fatal drowning often experience severe motor deficits but maintain relatively intact perceptual and cognitive capabilities.

Experiments in big animals show efficacy of new non-toxic MRI contrast agent

The top causes of death worldwide, ischemic heart diseases and stroke, together with another major source of illness, that is cancer, require proper imaging of blood vessels.

Researchers use imaging techniques to collect massive data on individual brains

A quest to analyze the unique features of individual human brains evolved into the so-called Midnight Scan Club, a group of scientists who had big ideas but almost no funding and little time to research the trillions of neural connections that activate the body's most powerful organ.

Third-person self-talk helps control emotion, says study

A study published online in a nature journal Scientific Reports suggests that talking in the third person to oneself in stressful times might help controlling emotions and it needs no additional mental effort than first person self-talk, which is normally used by people to talk to themselves.

'Residual echo' of Neanderthal genes may hold clues to deficits in mental disorders

Researchers at the National Institute of Mental Health have produced the first direct evidence that parts of our brains implicated in mental disorders may be shaped by a "residual echo" from our ancient past.

People with family history of bipolar disorder may 'age' more quickly than others

New King's College London research suggests that people with a family history of bipolar disorder may 'age' more rapidly than those without a history of the disease.

Research reveals differences in brain structure between boys and girls with antisocial behavior

The causes of severe antisocial behavior may differ between boys and girls, which could pave the way for new sex-specific treatments, according to a major new study published today.

US FDA approves MRI especially for newborns

The U.S. Food and Drug Administration yesterday approved the first magnetic resonance imaging (MRI) device that can be specifically used in neonates or newborn babies. These MRI devices would be used for imaging of the brains and head in neonates who are admitted to the neonatal intensive care units (NICU) where they are necessary.

Scientists create new probe for imaging proteins involved in fibrogenesis

Organs respond to injuries with the formation of new fibrous tissue, which can result in scarring. This process called fibrogenesis can now be monitored noninvasively on a molecular level, as American scientists report in the journal Angewandte Chemie.

Scientists find greater cortical thickness in the brains of elderly female yoga practitioners

Scientists in Brazil have imaged elderly female yoga practitioners' brains and found they have greater cortical thickness in the left prefrontal cortex, in brain areas associated with cognitive functions like attention and memory.

Researchers develop metal-free contrast agent that could be safer for high-risk patients

To enhance the visibility of organs as they are scanned with magnetic resonance imaging (MRI), patients are usually injected with a compound known as a contrast agent before going into the scanner. The most commonly used MRI contrast agents are based on the metal gadolinium; however, these metal compounds can be harmful for young children or people with kidney problems.
