Automated coronary plaque analysis predicts future events
March 3, 2016 -- VIENNA - Automated plaque analysis in coronary CT angiography can predict which patients with known ST-segment elevation myocardial infarction may go on to have a heart attack in the future, concluded a Wednesday presentation at ECR 2016.  Discuss
Midlevel image features help CAD find lymph nodes
February 29, 2016 -- Using midlevel image features in computer-aided detection (CAD) algorithms represents a step back from the latest deep machine-learning techniques, but such features produce a more transparent process with potentially more accurate results, according to new research from the U.S. National Institutes of Health.  Discuss
What would it take to build a better PACS workstation?
February 16, 2016 -- If you could build a better PACS workstation, what would you include? A pair of researchers tackled that question in a new article published online February 9 in the Journal of the American College of Radiology.  Discuss
Virtual reality goggles can make users queasy
February 1, 2016 -- In a stroke of virtual irony, people with the best 3D vision are the most likely to experience motion sickness when viewing virtual reality displays, according to new research in the journal Entertainment Computing.  Discuss
Algorithm corrects contrast enhancement artifacts in dual-source CTC
January 25, 2016 -- A new postprocessing technique for dual-source CT colonography (CTC) corrects for artifacts that mimic contrast enhancement created by fecal tagging materials. The algorithm boosts sensitivity and reduces false-positive detections significantly.  Discuss
Study finds differences in how breast density is measured
January 20, 2016 -- A study of nearly 2,000 breast cancer patients who underwent screening mammography found significant differences between three different methods of measuring breast density -- though breast cancer risk predictions were similar among the techniques, concludes a report in Radiology.  Discuss
Cardboard VR viewer helps docs see infant's heart defects
January 18, 2016 -- Florida doctors were able to plan a successful surgical procedure on an infant with severe heart defects, using cardiac CT images visualized with a virtual reality (VR) image viewer made from cardboard.  Discuss
Motion correction improves CT lung tumor assessment
December 17, 2015 -- Perfusion CT is emerging as a useful way to assess the treatment of lung cancer patients, but respiratory motion can cause problems with images. Fortunately, researchers from California and Pennsylvania have discovered a motion correction algorithm that can help.  Discuss
Automated CAC fares well in CT lung screening scans
December 7, 2015 -- CHICAGO - Automated coronary artery calcium (CAC) scoring is robust and accurate when applied to lung cancer screening exams -- even when applied to a different population than the algorithm was designed for, according to results presented on Thursday at the 2015 RSNA meeting.  Discuss
CT, 3D printing help team separate conjoined girls
December 3, 2015 -- CHICAGO - In an amazing 26-hour operation, a multidisciplinary team used CT scans and a 3D-printed model of the organs of conjoined twins to help perform a successful separation. Details of the effort were presented at this week's RSNA conference.  Discuss
