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.
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).
Study reaffirms value of chest radiography
August 11, 2006 -- As medical imaging goes increasingly high-tech, a new study out of the Netherlands indicates that the workhorse of radiology -- the chest x-ray -- remains a cost-effective exam that impacts patient management in a majority of cases.
High rate of unexpected lung cancers found on routine CT scans
May 24, 2006 -- SAN DIEGO - One-fifth of consecutive CT scans for all indications in a U.K. teaching hospital demonstrated a new malignancy, according to a study presented Monday at the American Thoracic Society (ATS) conference.
CT, MRI show successful vocal cord restoration
May 10, 2006 -- A new vocal cord restoration technique injects the body's own fat into damaged vocal cords to restore damaged voice quality. Imaging with CT and MRI show that vocal function not only improves after the procedure, but endures over follow-up periods of at least four years.
Swedes want to perform VC, but many lack equipment, training
May 8, 2006 -- Less than a quarter of Sweden's radiology departments perform virtual colonoscopy, but not for lack of interest in the procedure, a new study finds. Rather, the lack of multidetector CT scanners and training opportunities were the top reasons for not performing VC.
