Right heart quantification awareness: Part 5
October 11, 2017 -- The right heart has jokingly been referred to as the organ's stepchild, with little attention paid to its size, function, and prognostic implications. In this column, Judith Buckland of CardioServ reviews the proper methods to quantify the right heart for both size and function on echocardiography.  Discuss
NIH opens massive x-ray database to propel AI research
October 10, 2017 -- Optimizing artificial intelligence (AI) algorithms for medical applications demands immense stores of imaging data. Researchers may now begin sating that need thanks to an enormous database of chest x-rays recently made available by the U.S. National Institutes of Health (NIH).  Discuss
