CCTA increases emergency room costs, length of stay
November 17, 2017 -- Coronary CT angiography (CCTA) might not be an ideal diagnostic tool for patients presenting to the emergency room with acute chest pain, according to a study published online November 14 in JAMA Internal Medicine. Researchers found that CCTA increases the length of stay without improving clinical outcomes any more than clinical evaluation alone.  Discuss
Nodule count on CT not linked to lung cancer risk
November 14, 2017 -- Does a higher number of lung nodules detected on baseline CT screens indicate an increased risk of cancer? Researchers with the Dutch-Belgian Randomized Lung Cancer Screening trial refute this notion in a study published in the November issue of Lung Cancer.  Discuss
Deep learning differentiates liver masses on CT
November 10, 2017 -- A deep-learning approach using a convolutional neural network can accurately classify liver masses into five categories based on dynamic contrast-enhanced CT images, according to research from Japan published online recently in Radiology.  Discuss
Chest doctors issue guidelines for CT lung cancer screening
November 10, 2017 -- An expert panel of chest physicians has updated its guidelines for low-dose CT lung cancer screening based on a review of results from various trials. The group presented its proposal at the American College of Chest Physicians annual meeting last month in Toronto.  Discuss
How accurate is CT radiation dose info on the internet?
November 8, 2017 -- The internet often harbors inaccurate information regarding CT radiation dose, with online media outlets aimed at the lay public leading the way, according to a new study published online in the Journal of the American College of Radiology.  Discuss
New solid nodules may increase lung cancer risk
November 7, 2017 -- Lung nodules found on follow-up CT lung screening rounds could be more dangerous than those found on baseline exams, according to a new analysis of data from the National Lung Screening Trial. The findings are published in the November issue of the American Journal of Roentgenology.  Discuss
UCLA offers ambulatory stroke care with mobile CT
October 30, 2017 -- In a pilot project, University of California, Los Angeles (UCLA) Health has launched a specialized ambulance unit that is prepared to treat stroke patients on the spot using a mobile CT scanner.  Discuss
Canadian risk model boosts CT lung screening efficiency
October 24, 2017 -- Is the risk model used in the National Lung Screening Trial really the best one for determining which individuals should get CT screening for lung cancer? Maybe not, according to Canadian researchers who published what they think might be a more effective model in an October 17 paper in Lancet Oncology.  Discuss
AI algorithm predicts lung disease, adverse events on CT
October 13, 2017 -- Recent studies have demonstrated the power of artificial intelligence (AI) software to detect disease, but how well can it predict future adverse events? The extent to which AI can assess smokers' risk for lung disease on CT was reported in a new study published in the American Journal of Respiratory and Critical Care Medicine.  Discuss
AI gives one-stop shopping for urinary stone evaluation
October 5, 2017 -- An artificial intelligence (AI) algorithm can accurately detect and classify urinary stones based solely on images from noncontrast single-energy CT scans, according to research presented at last week's Society for Imaging Informatics in Medicine's Conference on Machine Intelligence in Medical Imaging.  Discuss

6 tips for joining a CT lung cancer screening registry

On February 5, 2015, the U.S. Centers for Medicare and Medicaid Services issued a national coverage determination (NCD) that found the evidence is sufficient to permit high-risk patients to receive annual low-dose CT scans for lung cancer screening without cost sharing. Read more
