Medical images unlikely to change risky behavior, study shows January 25, 2010 -- If you show an obese person a medical image of their plaque-clogged arteries, will it help motivate them to get more exercise? Not necessarily, although you might have better luck getting smokers to change their ways, according to a new review of literature from the Cochrane Collaboration.
Handheld devices show promise in emergency radiology January 21, 2010 -- Handheld devices such as the iPod Touch may be suitable to review medical images in emergency radiology consultations, according to research published in the February issue of the American Journal of Roentgenology.
Italian researchers cut gadolinium dose -- as well as NSF risk January 21, 2010 -- A half dose of a commercially available MRI contrast agent works as well as a full dose in patients with acute myocardial infarction, according to Italian researchers. The findings show it's possible to achieve shorter imaging times while protecting renally impaired cardiac patients at risk for nephrogenic systemic fibrosis (NSF).
Experience counts when reading contrast ultrasound liver images January 19, 2010 -- Radiologists with experience reading contrast-enhanced ultrasound images have the upper hand over neophytes in characterizing malignant liver tumors, according to research published in the January issue of the Journal of Ultrasound in Medicine.
DOPA-PET/CT can alter therapy for neuroendocrine tumors January 15, 2010 -- Swiss researchers have found that combined fluorine-18 dihydroxyphenylalanine (F-18 DOPA) contrast-enhanced PET/CT is "significantly superior" to DOPA-PET and contrast-enhanced CT in detecting neuroendocrine tumors.
CTA motion model aims to improve cardiac function analysis January 11, 2010 -- Dutch researchers used an automated coronary artery motion model to analyze cardiac function from electrocardiogram-gated coronary CT angiography (CTA) data. The method promises to improve cardiac function analysis and reconstruction interval selection, and even provide new information on coronary artery motion at different heart rates.
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.
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.
