Better than mammography? CT lung screening is cost-effective June 25, 2013 -- The economics of CT lung cancer screening measure up to other population-based screening programs such as mammography in terms of cost-effectiveness, according to an analysis of data from the National Lung Screening Trial that was presented on Monday at a U.S. National Cancer Institute meeting.
Patient factors, not doctors, affect emergency imaging June 25, 2013 -- Little of the geographic variations in emergency department imaging use can be attributed to physician characteristics such as experience, training, or gender, according to a new study published online in Radiology. In fact, variations in imaging use have more to do with patients.
Survey finds U.S. installed base of gamma cameras is aging June 24, 2013 -- The average age of gamma cameras at nuclear cardiology labs in the U.S. grew by two years between 2009 and 2011, according to a survey from the University of Missouri.
