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

Researchers use brain imaging to uncover susceptibility to psychological stress and trauma

Most people have intense emotional reactions to traumatizing events like road accidents or combat. But some suffer far longer, caught in the grip of long-term debilitating disorders such as Post-Traumatic Stress Disorder (PTSD). Because doctors cannot predict who will develop these disorders, however, early or preventive intervention is not available. Now, a new project led by researchers at Tel Aviv University seeks to identify pre-traumatic subjects - those who are more susceptible to long-standing disorders if exposed to a traumatic incident.

Significant increase in use of CT, MRI and PET imaging over the last two decades

Among six large integrated health care systems between 1996 and 2010 there was a substantial increase in the use of advanced diagnostic imaging, including approximately a tripling of the use of computed tomography and nearly a quadrupling of the use of magnetic resonance imaging, as well as a substantial increase in estimated radiation exposure, according to a study in the June 13 issue of JAMA.

New study on motor chunking

You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements.

Experimental drug and genetic differences indicate how people deal with fear and stress

Researchers at Duke University and the National Institutes of Health have found a way to calm the fears of anxious mice with a drug that alters their brain chemistry. They've also found that human genetic differences related to the same brain chemistry influence how well people cope with fear and stress.

Cyberonics, Imricor enter agreement to develop MRI compatible leads for VNS Therapy System

Cyberonics, Inc. today announced that it has entered into an exclusive technology license agreement with Imricor Medical Systems, Inc. to develop Magnetic Resonance Imaging ("MRI") compatible leads for use with the VNS Therapy System (Vagus Nerve Stimulation).

MRI scans reveal how sleep deprivation impairs brain regions associated with food processing

MRI scans from a study being presented today at SLEEP 2012 reveal how sleep deprivation impairs the higher-order regions in the human brain where food choices are made, possibly helping explain the link between sleep loss and obesity that previous research has uncovered.

Study uses brain scans to better understand link between sleep restriction and obesity

The sight of unhealthy food during a period of sleep restriction activated reward centers in the brain that were less active when participants had adequate sleep, according to a new study using brain scans to better understand the link between sleep restriction and obesity.

Effective ways of detecting onset of kidney disease

Research led by an Arizona State University biomedical engineer and physicist to find more effective ways of detecting the onset of kidney disease is getting support from the National Institutes of Health.

Concussion victims have unique spatial patterns of brain abnormalities that change over time

Patients vary widely in their response to concussion, but scientists haven't understood why. Now, using a new technique for analyzing data from brain imaging studies, researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center have found that concussion victims have unique spatial patterns of brain abnormalities that change over time

Pathophysiologic differences evident between schizophrenia, bipolar

Review findings reveal differences in the pathophysiology of bipolar disorder and schizophrenia, relating specifically to the medial temporal lobe and associated limbic regions.

Risk of leukaemia and brain cancer in children could be tripled by radiation exposure from CT scans

Radiation exposure received from 2 to 3 computed tomography (CT) scans of the head in childhood (aged under 15 years)—giving a cumulative dose of around 60 mGy— can triple the risk of later developing brain cancer, while around 5 to 10 such scans (cumulative dose around 50 mGy) could triple the risk of developing leukaemia (with the differing number of scans related to different absorption rates of the brain versus the bone marrow and age at time of scanning).

Strong link between functional brain impairment and post-stroke depression

Researchers studying stroke patients have found a strong association between impairments in a network of the brain involved in emotional regulation and the severity of post-stroke depression. Results of the study are published online in the journal Radiology.

Study reveals new evidence of trans-cranial bright light's effect to brain functions

A recent placebo-controlled study reveals new evidence of trans-cranial bright light's effect to brain functions when administered through the ear. Bright light stimulation was found to increase activity in brain areas related to processing of visual sensory information and tactile stimuli. The findings constitute the first ever published scientific article about functional modulation of the brain with bright light delivered to the brain through the ears. The study was published today May 29th, 2012 in the World Journal of Neuroscience.
