German screening trial finds high accuracy for VC January 17, 2007 -- Results from the first 300 patients screened in the ongoing Munich Colorectal Cancer Prevention Trial indicate that virtual colonoscopy with 64-slice CT is sensitive and specific for the detection of polyps of all sizes. The researchers in Germany found that conventional colonoscopy had a slight edge in diminutive polyps, but virtual colonoscopy did a little better with the larger lesions.
French firm Biospace Med prepares for launch of EOS digital x-ray unit December 25, 2006 -- The vast majority of radiography systems currently on the market -- both digital and analog -- are based on a fairly conventional design that hasn't changed much in decades: an x-ray tube at one end and a film-screen cassette or detector at the other. But the new EOS system from French biotech firm Biospace Med represents a radical new design in digital radiography instrumentation that could carve out a niche when it becomes available in mid-2007.
CTCA shows cost-effectiveness in the EU November 27, 2006 -- CHICAGO - CT coronary angiography (CTCA) demonstrates a cost-effective method in the European Union (EU) for the diagnosis of coronary artery disease compared with traditional diagnostic modalities, according to data presented by German researchers at the 2006 RSNA meeting on Monday.
MRI, US far from idle for hand, wrist injuries November 6, 2006 -- MRI and ultrasound are equally valuable for assessing such conditions as tenosynovitis, skier's thumb, and vascular flow, according to several recently released studies. Researchers in Switzerland discuss why and how they use MR imaging for the small vessels of the hand. Meanwhile, investigators in Italy and Belgium put ultrasound to the test in the wrist and thumb.
Antiscatter grids may not be helpful in some DR applications September 22, 2006 -- In the quest for an optimum balance between image quality and radiation dose in digital radiography (DR), a U.K. group looked at whether better DR image quality provided through the use of an antiscatter grid justified an increase in effective dose to patients.
Dynamic contrast-enhanced MRI shows promise in mesothelioma September 15, 2006 -- An international group of researchers said they have encouraging preliminary results from the use of dynamic contrast-enhanced MRI (DCE-MRI) to help determine the malignancy of cancer cells in the protective sac -- the mesothelium -- that surrounds most of the body's internal organs.
Two studies define role of molecular imaging, therapy in endocrine carcinoma September 14, 2006 -- Digestive endocrine tumors would seem to be as intricate as the digestive system itself, so it's no wonder that clinicians are searching for the best imaging modality to diagnose, differentiate, and treat endocrine tumors. Two recent studies looked at how molecular imaging and therapy fared in this disease. A group from Poland evaluated endocrine cancer response to treatment with a radiolabeled somatostatin analogue, while researchers in France tested two molecular imaging techniques in endocrine cancers as a tool for diagnosis and staging.
Ultrasound screening reveals unknown cardiovascular risk in women September 12, 2006 -- Sonographic screening can correctly identify women who may be at risk of heart disease or stroke, especially when traditional risk assessment methods fall short, according to a presentation at the 2006 European Society of Cardiology's World Congress of Cardiology in Barcelona, Spain.
Multislice CT almost as good as IVUS in acute coronary syndromes September 6, 2006 -- BARCELONA - In the early stage of acute coronary syndrome, 16-slice multidetector-row CT can locate the culprit lesion, according to a presentation this week at the European Society of Cardiology's World Congress of Cardiology. Researchers from University Hospital in Bordeaux, France compared 16-slice CT to 40-MHz catheter-based intravascular ultrasound (IVUS).
