2 acceleration methods make scanning more than 7 times faster An international team of physicists and neuroscientists has reported a breakthrough in magnetic resonance imaging that allows brain scans more than seven times faster than currently possible. In a paper that appeared Dec. 20 in the journal PLoS ONE, a University of California, Berkeley, physicist and colleagues from the University of Minnesota and Oxford University in the United Kingdom describe two improvements that allow full...

The brains of fighter pilots are significantly different from those of the average individual, claims a new study published Tuesday in the Journal of Neuroscience. Using a series of cognitive tests and MRI scans, researchers from University College London (UCL) studied 11 front-line Tornado fighter pilots from the Royal Air Force (RAF). Each of the pilots were asked to complete two "cognitive control" tasks centered around rapid decision making, and also had their brains scanned using a type...

Magnetic resonance imaging (MRI) of the brain could expand the number of stroke patients eligible for a potentially life-saving treatment, according to a new study, published online and in the December issue of the journal Radiology. Some patients who suffer an acute ischemic stroke "” in which a blood clot or other obstruction blocks blood flow in the brain "” can be treated with a drug called tissue plasminogen activator, or tPA, that dissolves the clot and restores blood flow....

The most detailed magnetic resonance images ever obtained of a mammalian brain are now available to researchers in a free, online atlas of an ultra-high-resolution mouse brain, thanks to work at the Duke Center for In Vivo Microscopy. In a typical clinical MRI scan, each pixel in the image represents a cube of tissue, called a voxel, which is typically 1x1x3 millimeters. "The atlas images, however, are more than 300,000 times higher resolution than an MRI scan, with voxels that are 20...

Doctors should use a diffusion MRI scan to diagnose stroke instead of a CT scan, according to a new guideline from the American Academy of Neurology. The guideline is published in the July 13, 2010, issue of Neurology®, the medical journal of the American Academy of Neurology. "While CT scans are currently the standard test used to diagnose stroke, the Academy's guideline found that MRI scans are better at detecting ischemic stroke damage compared to CT scans," said lead...

Early knowledge of hepatocellular carcinoma (HCC) response to transcatheter arterial chemoembolization (TACE) is crucial for determining treatment success, timing of repeat treatment, and patient prognosis. Currently, magnetic resonance imaging (MRI) is used 1-3 mo after treatment to evaluate anatomical tumor response, based upon changes in tumor size and contrast-agent enhancement. Alternatively, diffusion-weighted imaging (DWI) can be used as a functional imaging technique to depict...

Scientists at the University of Kentucky's College of Medicine have identified changes in the brains of normal individuals at high risk for Alzheimer's disease that could prove important for early detection of the disease. The research, led by Brian Gold, associate professor of anatomy and neurobiology, focused on the brain's white matter, which forms the majority of deep parts of the brain and consists primarily of myelinated nerve cell processes, or axons. These myelinated axons serve to...

Children with dyslexia often struggle with reading, writing, and spelling, despite getting an appropriate education and demonstrating intellectual ability in other areas. New neurological research has found that these children's difficulties with written language may be linked to structural differences within an important information highway in the brain known to play a role in oral language. The findings are published in the June 2010 issue of Elsevier's Cortex. Vanderbilt University...
