FDG-PET distinguishes Parkinson's from other disorders
January 11, 2010 -- With the help of FDG-PET, researchers in New York have developed an automated image-based classification procedure to differentiate patients with idiopathic Parkinson's disease from those with other brain diseases such as multiple system atrophy and progressive supranuclear palsy.
VA report: 'Tension' at Utah IR unit did not cause patient deaths
January 8, 2010 -- An investigation by the U.S. Department of Veterans Affairs (VA) of a VA hospital in Salt Lake City found evidence of "tension" between interventional radiologists and vascular surgeons, but reported that the situation did not "directly contribute" to the deaths of four patients at the facility within a nine-month period.
DSCT edges out 64-slice CT in coronary artery imaging
January 8, 2010 -- Coronary CT angiography performed on dual-source CT (DSCT) confers a slight advantage in image quality with slightly fewer nondiagnostic vessel segments compared to 64-detector-row CT. Calcification remains a challenge with both types of scanners, but it's slightly less problematic with dual-source systems, say researchers from the University of Rome.
Colonoscopy surveillance barely lowers CRC rates
January 8, 2010 -- Despite frequent colonoscopic surveillance, patients whose advanced adenomas had been removed had higher-than-expected rates of colorectal cancer (CRC) at follow-up, according to a new surveillance study that followed patients for more than four years after polypectomy.
Study finds sharp rise in prenatal ultrasound use in Canada
January 7, 2010 -- There was a 55% increase in the rate of ultrasound utilization among pregnant women between 1996 and 2006 in the Canadian province of Ontario, according to a study published online January 4 in the Canadian Medical Association Journal.
Healthcare IT pays off, but don't hold your breath
January 7, 2010 -- Investing in healthcare IT projects such as electronic health records (EHR) and e-prescription systems produces significant socioeconomic benefits, but it can take nearly 10 years to see the first positive returns, according to a new study from Europe.
European cancer rates declining, report indicates
January 7, 2010 -- Cancer mortality is steadily declining in Europe, echoing a trend also being seen in the U.S. and Japan, according to a study comparing cancer deaths between 1990-1994 and 2000-2004. In the European Union, mortality rates for all cancers fell by 10% in men and 8% in women.
MRI aids US in detecting placenta accreta in pregnant women
January 6, 2010 -- Researchers from the University of California, San Diego are recommending the use of MRI to detect placenta accreta when ultrasound exams prove inconclusive. Their study found that MRI is a useful and accurate adjunct to ultrasound to diagnose the potentially life-threatening condition.
DTI beats standard MRI in predicting early memory loss, study shows
January 6, 2010 -- Italian researchers say that MRI with a diffusion tensor imaging (DTI) technique appears to be superior to conventional MRI in detecting brain changes that predict future memory decline, according to a study published online on January 6 in Neurology.
