Food for thought: Neuroimaging offers clues into eating-related psychopathology
March 2, 2007 -- In honor of National Eating Disorders Awareness Week, surveyed the latest research in eating-related imaging using functional MRI (fMRI). The European and U.S. studies examined appetite-related brain activity, the subjective quality of appetite, and cerebral processing of food-related stimuli by gender, as well as hunger and satiety in anorexia patients.
Testing procedure improves usability of DICOM CDs
January 22, 2007 -- DICOM CDs are commonly used today to disseminate patient images and information, but many of them suffer from deficiencies that can hinder image viewing and integration into PACS networks. To help deal with the problem, the German Roentgen Society (DRG) initiated a quality assurance initiative designed to improve the quality of DICOM CDs.
GE Healthcare to expand once more with $8 billion Abbott deal
January 19, 2007 -- GE Healthcare of Chalfont St. Giles, U.K., today released more details regarding its proposed $8.13 billion acquisition of Abbott Laboratories' primary in vitro diagnostics businesses and Abbott Point-of Care diagnostics business (formerly known as i-STAT).
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.
Student-designed CT-guided biopsy device shows early promise
September 19, 2006 -- Three graduate students have developed a CT-guided breast biopsy device, which may make needle biopsies less invasive and reduce potential complications for lung cancer patients as well.
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.
