FFR-CT cuts time, costs in patients with chest pain December 8, 2016 -- Belgian researchers said they have achieved remarkable reductions in costs, radiation dose, and -- most important -- negative angiography studies by implementing fractional flow reserve CT (FFR-CT) to manage the care of patients with chest pain who have an intermediate risk of coronary disease.
Study: Reduce CT kV levels to lower breast dose in patients December 7, 2016 -- Despite a short scan length and relatively small dose length product, contrast-monitoring scans can account for 27% of the overall breast dose accrued from a CT pulmonary angiography study, according to Irish researchers. A small tweak to the kilovoltage (kV) can significantly reduce radiation dose to the breast, they noted.
How to inseminate a beluga whale December 7, 2016 -- Spanish radiologists have helped perform the artificial insemination of a beluga whale, and they hope the new approach can boost reproduction in endangered marine mammals. The team explains how the technique can improve conception rates during artificial insemination and bolster conservation.
PACS displays influence brain ischemia detection December 6, 2016 -- The specifications of LCD monitors -- specifically spatial resolution and luminance -- play an important role in the ability to detect brain ischemia on CT studies, particularly for less experienced radiologists, Italian researchers reported at last week's RSNA 2016 meeting in Chicago.
U.K. releases new guidance on chest pain December 6, 2016 -- The U.K. National Institute for Clinical Excellence published its long-awaited update to the chest pain guidelines on 30 November, with leading cardiac imaging specialists issuing a positive, but cautious, response to the new document.
Study suggests short-term sleep loss hurts the heart December 5, 2016 -- CHICAGO - Using cardiac MRI, researchers from Germany found that going without sleep for a short period of time appeared to affect cardiac function in radiologists. Results of the study were presented at the RSNA annual conference.
Video from RSNA 2016: AI and radiology -- Separating hope from hype December 2, 2016 -- CHICAGO - Artificial intelligence (AI) is one of the most hyped -- and most feared -- technologies to come along in radiology in years. Dr. Paul Chang from the University of Chicago separates AI's hope from hype in this video interview from RSNA 2016.
Food for thought: Rice bodies puzzle MSK experts December 1, 2016 -- Rice bodies are unique to musculoskeletal (MSK) radiology, but their pathogenesis and significance in articular tissue response to inflammation are still unclear, according to award-winning research from Turkey presented at RSNA 2016.
Prostate CAD boosts detection for most readers December 1, 2016 -- CHICAGO - MRI-based computer-aided detection (CAD) can improve detection sensitivity for prostate cancer for most readers, while reducing reading time fourfold, according to a 29 November presentation at RSNA 2016.
