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. Read More
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. Read More
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. Read More
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. Read More
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. Read More
DNA defect predicts RT outcome for endometrial cancer
January 6, 2010 -- Radiation therapy (RT) may not be an effective treatment for women diagnosed with endometrioid endometrial cancer whose tumors have a DNA deficiency, according to preliminary research from the Canary Institute for Cancer Research in Las Palmas, Spain. Read More
Ultrasound elastography characterizes fibrosis severity
January 6, 2010 -- A Spanish research team has found that ultrasound elastography can reliably differentiate between rapid or slow fibrosis in liver transplant patients, paving the way for earlier identification of patients at risk of hepatitis C recurrence. Read More
Patients with peripheral arterial disease may need cardiac imaging
December 30, 2009 -- As many as one in five patients being treated for peripheral arterial disease have concurrent -- but silent -- asymptomatic coronary artery disease that's severe enough to require invasive procedures, according to a study presented at the RSNA meeting earlier this month.

VC CAD aids experts in detecting intermediate polyps
December 28, 2009 -- Computer-aided detection (CAD) can improve the performance of experienced radiologists in detecting intermediate-sized (6- to 9-mm) polyps, but it doesn't help find larger lesions, said researchers from Italy in results presented at the RSNA meeting earlier this month. Read More
Lesion size and morphology at VC good predictors of histology
December 22, 2009 -- Size and morphology are good predictors of whether a colorectal lesion harbors advanced histology and needs to be removed, according to a new multicenter study from Italy. The results suggest that polyps of the same size detected at virtual colonoscopy could be classified and managed differently based on their morphology. Read More
