4-scan PET/MRI exams improve breast imaging

JAMA: Adding tomo to mammography finds more cancer
June 24, 2014 -- Adding digital breast tomosynthesis to mammography screening boosts the detection of invasive cancer by more than a third compared to mammography alone while reducing the number of false positives by 15%, according to a study in the June 25 issue of the Journal of the American Medical Association.
Lung cancer screening of seniors: Should CMS regulate?
June 24, 2014 -- A just-published proposal in the Annals of Internal Medicine seeks to balance the benefits and harms of CT lung cancer screening by limiting the screening of Medicare beneficiaries to lung cancer screening centers that would be accredited based on still-evolving society-based guidelines.
