February 13, 2018 -- French researchers found that a set of clinical criteria was just as accurate as a protocol that included CT pulmonary angiography for ruling out pulmonary embolism (PE) in the emergency department, according to an article published in the February 13 issue of the Journal of the American Medical Association.  Discuss
Patients want more imaging info -- and before their exams
February 13, 2018 -- How much information do patients want before imaging exams? Certainly more than they're getting, according to a study published online February 13 in Radiology. In fact, more than half seek information about the procedure on their own beforehand, and one in five patients show up for the exam without having received any information about it.  Discuss

Deep-learning algorithm can assess breast density
February 9, 2018 -- A deep-learning algorithm can provide fully automated analysis of breast density on screening mammography exams, yielding density estimates that correlate well with assessments provided by radiologists, according to research published online January 24 in Medical Physics.  Discuss
5 ways to optimize CT lung cancer screening
February 9, 2018 -- An academic hospital that implemented a CT lung cancer screening program obtained similar detection rates as the National Lung Screening Trial. But it also encountered challenges that needed to be addressed to improve the quality of screening, which researchers describe in a new study published in Academic Radiology.  Discuss
