CT explores size, growth of ground-glass nodules
February 24, 2010 -- Two studies recently published online in Radiology yield important new information about CT-detected part-solid lung nodules. Mass measurements of ground-glass nodules are the most accurate, say Dutch researchers, but a Korean group found that most part-solid nodules disappear over time -- and do so in predictable ways.
VC obviates need for colonoscopy even in symptomatic patients
February 24, 2010 -- Even among individuals with symptoms suggesting a higher risk of colorectal polyps and cancer, virtual colonoscopy screening is enough to prevent most of them from having to undergo invasive colonoscopy, according to a recent study from the Netherlands.
MRI plus film-screen mammo screening works for BRCA1 carriers
February 23, 2010 -- For women who are BRCA1 gene carriers, a combination of MRI and film-screen mammography is the most clinically effective combination for finding breast cancer. But it also costs more, according to a study published in the March issue of Radiology.
MRI enterography shows shortcomings for Crohn's disease
February 23, 2010 -- Although MRI enterography can diagnose important incidental findings in a minority of patients with suspected or known Crohn's disease, Dutch researchers have concluded that a substantial number of patients experience unnecessary morbidity because of additional examinations of benign or normal conditions.
Merge makes play for Amicas
February 22, 2010 -- Advanced visualization and healthcare IT developer Merge Healthcare is courting PACS vendor Amicas with an aggregate offer of $248 million in cash, but Amicas is advising shareholders to instead accept its current merger agreement with equity firm Thoma Bravo.
Avon: USPSTF guidelines already affecting access
February 22, 2010 -- In some states, women ages 40 to 49 have less access to mammograms since the U.S. Preventive Services Task Force (USPSTF) released its recommendations to change breast cancer screening guidelines last November, according to a recent survey conducted by the Avon Foundation for Women.
Coronary CTA and MR MPI have complementary roles
February 22, 2010 -- Coronary CT angiography (CTA) and MR myocardial perfusion imaging (MPI) work best as a team for evaluating chest pain patients with suspected coronary artery disease, according to a new study published online in Radiology.
FDG-PET/CT outdoes MDCT in certain colorectal cancer patients
February 22, 2010 -- Canadian researchers have found that FDG-PET/CT is more sensitive than MDCT in identifying recurrent and metastatic disease in patients with colorectal cancer and an elevated level of carcinoembryonic antigen (CEA), according to a study in the March issue of the American Journal of Roentgenology.
DR summit yields Image Gently CR/DR campaign, ACR dose registry
February 22, 2010 -- The Alliance for Radiation Safety in Pediatric Imaging has expanded the scope of its global Image Gently campaign to include computed radiography (CR) and digital radiography (DR) exams. The new initiative was formally launched -- along with a new American College of Radiology DR dose registry -- at a DR summit earlier this month.
Radiologists want more work, study suggests
February 19, 2010 -- The radiology employment market tipped from a shortage to a surplus in 2007, leaving radiologists hungry for more work, according to a new study to be published in the American Journal of Roentgenology. Why? Because imaging departments are increasingly productive and the workload hasn't caught up.
The Profit Center: Part 12 -- Exclusive contracts and hospital stipends under attack
February 19, 2010 -- Fear of rising healthcare costs is being exploited to attack exclusive agreements and stipend support from hospitals to hospital-based physicians, according to healthcare business and legal affairs expert Mark Weiss. He offers advice for counterattack in this edition of the Proft Center.
CDC report: MRI, CT, PET use spikes in physician offices, ER
February 18, 2010 -- The use of advanced diagnostic imaging in physician offices and emergency departments has increased dramatically over the past decade, according to a report issued this week by the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics.
New paper updates guidelines on fluoro radiation injuries
February 18, 2010 -- While much of the recent concern over medical radiation dose has focused on CT, fluoroscopy is another imaging modality that can pack a radiation wallop. In some cases, patients are leaving the fluoroscopy table unaware that they've received enough radiation to cause skin injury.
