A first glimpse at healthy brain and behavioral development
Yes, there are gender differences in cognitive function, but they're more limited than previously thought. And yes, income does affect cognitive performance - but less than expected when only healthy children are considered. view more (2007-05-18)
Damage to brain vessels increases the chance of dementia and depression
Dutch researcher Niels Prins has discovered that elderly people with a lot of damage to the small blood vessels in the brain have a greater chance of developing dementia or depression. The damage is visible on MRI scans as white matter lesions and infarcts of the brain. Elderly people with serious white matter abnormalities and infarcts were found... view more... (2004-04-13)
Ultrasound plus mammography finds more cancers, but increases false positives
Adding ultrasound to mammography finds more cancers than mammography alone, but also substantially increases the number of false positives, according to first-year results from a three-year study of the two tests. view more (2007-10-01)
Nanoparticles can track cells deep within living organisms
To the delight of researchers at Washington University School of Medicine in St. Louis, living cells gobbled up fluorine-laced nanoparticles without needing any coaxing. Then, because of the unusual meal, the cells were easily located with MRI scanning after being injected into mice. view more (2007-03-27)
Deep Organ Image MR Scan Development
Oxford Researchers have developed a new, simple, design of accessory MR surface coil which significantly enhances the quality and clarity of deep organ MRI images. A new design of magnetic resonance imaging surface coil has been developed in which the location, size and improved homogeneity of the magnetic field within the, so called, "sweet... view more...

Detecting bone erosion in arthritic wrists
Both magnetic resonance imaging (MRI) and computed tomography (CT) are more sensitive than radiography - the standard imaging technique - for detecting bone erosions in rheumatoid arthritis (RA). view more (2008-02-28)
Elasticity imaging identifies cancers and reduces breast biopsies
A new ultrasound technique allows radiologists to accurately distinguish benign from malignant breast lesions. Using elasticity imaging, researchers correctly identified both cancerous and harmless lesions in nearly all of the cases studied. view more (2006-11-28)
New image analysis techniques to monitor how breast tumours respond to drugs
New techniques that might allow magnetic resonance imaging (MRI), to be used to give doctors subtle information about a tumour’s physiology and how it reacts to drug therapy are being developed. view more (2001-12-18)
NIH study tracks brain development in some 500 children across US
Children appear to approach adult levels of performance on many basic cognitive and motor skills by age 11 or 12, according to a new study coordinated by the National Institutes of Health (NIH). view more (2007-05-18)
MS that Runs in Families Appears More Severe than Non-Familial MS
Magnetic resonance images (MRI) of a large group of patients with multiple sclerosis has provided the first evidence that those with a history of MS in their families show more severe brain damage than patients who have no close relatives with the disease. view more (2007-10-12)
3-D ultrasound scanner provides in-depth view of the brain
Biomedical engineers at Duke's Pratt School of Engineering have adapted a three-dimensional ultrasound scanner that might guide minimally invasive brain surgeries and provide better detection of a brain tumor's location. view more (2007-06-21)
EDINBURGH MEN SOUGHT FOR MEMORY LOSS STUDY
Professor Jonathan Seckl's team, based at the Centre for the Study of the Ageing Brain at the Western General Hospital, has already carried out research which indicates memory loss in the elderly may tie in with higher-than-normal levels of glucocorticoids, hormones which boost blood sugar levels in times of stress. The researchers believe... view more... (1999-06-21)
MRI findings help forecast prostate cancer prognosis
Magnetic resonance imaging (MRI) findings in patients about to undergo radiation therapy for prostate cancer can help predict the likelihood that the cancer will return and spread post-treatment, according to a new study published in the April issue of the journal Radiology. view more (2008-03-25)
World's most powerful MRI ready to scan human brain
The world's most powerful medical magnetic resonance imaging machine, the 9.4 Tesla at the University of Illinois at Chicago, has successfully completed safety trials and may soon offer physicians a real-time view of biological processes in the human brain. view more (2007-12-05)
Every moment counts: Predicting treatment responses earlier for brain tumor patients
Using metabolic or molecular imaging to measure brain tumor patients' response to treatment is a powerful predictor of survival, notes a first-of-its-kind study presented at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals. view more (2007-06-04)
Magnetic resonance imaging improves breast cancer diagnosis
Women who have been diagnosed with breast cancer in one breast have a higher risk of contracting the disease in their opposite breast as well. A thorough examination of the opposite breast using mammography and ultrasound is therefore common practice. view more (2007-03-29)
Picture this: FSU professor's research could lead to vastly improved medical imaging
Magnetic resonance imaging, or MRI, has revolutionized health care, providing doctors with a highly accurate, non-invasive tool for diagnosing cancer, injuries and other maladies within the human body. view more (2007-02-14)
Twins study shows genetic basis for face and place recognition
New evidence suggests our brains are hardwired before birth to recognize faces and places. But in contrast, the neural circuitry we use to recognize words develops mainly as a result of experience. view more (2007-12-20)
Researchers use light to detect Alzheimer's
A team of researchers in Bedford, Mass. has developed a way of examining brain tissue with near-infrared light to detect signs of Alzheimer's disease. view more (2008-03-17)
Remote-control MRI exam performed over the Internet
Radiologists have developed a remote-control mechanism that allows an experienced off-site operator to control a magnetic resonance imaging (MRI) machine by logging onto the Internet from a personal computer. view more (2006-10-25)
