DBT boosts mammo's specificity, lowers recall rate
July 29, 2015 -- Adding digital breast tomosynthesis (DBT) to conventional mammography boosted the specificity of breast screening and cut the recall of women with benign lesions by more than half, according to a new study published in Radiology. DBT plus mammography also showed sensitivity gains in some groups of women.
CMS forecasts 'modest' growth in healthcare spending
July 29, 2015 -- The U.S. will see a "modest" increase in healthcare spending through 2024, but the projected 5.8% annual rate of growth is much lower than the rapid pace seen prior to 2008, according to a new report from the U.S. Centers for Medicare and Medicaid Services (CMS).
Mammography screening at 40 works, Lancet study finds
July 29, 2015 -- There is indeed a reduction in breast cancer mortality as a result of mammography screening in women who start getting exams at age 40 -- at least in the first 10 years of follow-up, according to a new study in Lancet Oncology that followed women for 17 years.
MRI links cardiac risk factors to cognition problems
July 28, 2015 -- MRI scans have demonstrated smaller regional brain volumes in people with certain cardiovascular risk factors, which could put them at risk for developing adverse cognitive issues, according to a study published online July 28 in Radiology.
New Mayo scoring system predicts CCU patient mortality
July 28, 2015 -- A predictive scoring system that combines both echocardiography and clinical data can reliably estimate three-year death rates in critical care unit (CCU) patients, according to research from the Mayo Clinic in Rochester, MN. The model is built on the fact that more heart patients are dying from noncardiovascular diseases.
Guerbet bids to buy Mallinckrodt's contrast business

The $270 million deal will double Guerbet's annual revenues, expand its product line, and instantly make the company a major player in the U.S. contrast market.
FDA eyes risks of gadolinium contrast brain deposits
July 27, 2015 -- The U.S. Food and Drug Administration (FDA) on Monday announced that it will investigate the risk of gadolinium-based contrast agents in the wake of several recent studies that found gadolinium deposits in the brains of some patients years after they received contrast-enhanced MRI scans.
Study maps CT radiation doses in 200K exams
July 27, 2015 -- Have you ever wondered how your facility's CT radiation dose levels stack up against those of other institutions? A study in Radiology describes the experience of researchers from five University of California campuses who measured dose in nearly 86,000 adults and children undergoing common CT scans.
Software aims for realism in echocardiography
July 27, 2015 -- A new echocardiography software package released this month analyzes cardiac structure and function pixel by pixel to render detailed functional 3D images that could speed up diagnosis and reduce the number of exams needed in patients undergoing cardiac workups.
Repeat MRI scans due to patient motion mean lost revenue
July 24, 2015 -- Having to retake MRI scans due to patient motion can easily cost a hospital upward of $100,000 in lost annual revenue, according to a study published in the July issue of the Journal of the American College of Radiology.
