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 (DLP), contrast-monitoring scans can account for 27% of the overall breast dose accrued from a CT pulmonary angiography (CTPA) study, according to Irish researchers. A small tweak to the kilovoltage (kV) can significantly reduce radiation dose to the breast, they noted.
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 not clear, according to award-winning research from Turkey presented at RSNA 2016 this week.
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.
Volleyball injuries: Which modality is best? November 30, 2016 -- New international research on musculoskeletal trauma of the ankle, knee, shoulder, spine, and hands resulting from volleyball has identified the best imaging modality to use in a range of clinical situations.
An occasional drink doesn't hurt coronary arteries November 30, 2016 -- CHICAGO - Having an alcoholic drink once or twice a day does not appear to affect the coronary arteries, based on scans with coronary CT angiography, researchers reported on 29 November at the RSNA annual meeting.
Minimal side effects from 7T MRI subside in minutes November 29, 2016 -- CHICAGO - In a new study, German researchers found that side effects related to a patient's balance after a 7-tesla MRI scan dissipated within minutes, according to results presented on Monday at RSNA 2016.
