Cardiac risk grows with higher coronary calcium scores
March 15, 2019 -- Individuals with high CT coronary artery calcium scores -- at least 1,000 Agatston units -- had a substantially greater risk of all-cause mortality than those with lower scores and nearly triple the risk of those with a score of 0, according to research published online March 15 in JACC: Cardiovascular Imaging.  Discuss
Risk prediction model boosts accuracy of CT lung screening
March 14, 2019 -- Researchers from the University of Pittsburgh developed a statistical model that combined data from CT scans with patient demographic information to predict an individual's risk of lung cancer on CT lung screening exams. The model worked better than several more-established methods, according to an article published online March 12 in Thorax.  Discuss
