Risk model improves accuracy of CT lung cancer screening
September 16, 2019 -- Using a risk-prediction model to determine eligibility for CT lung screening is more effective for detecting cancers than current guidelines from the U.S. Preventive Services Task Force, according to new results from the International Lung Screen Trial presented at the recent World Conference on Lung Cancer in Barcelona, Spain.  Discuss
Stroke care looks skyward with new mobile CT program
September 11, 2019 -- The notion that stroke care could one day take to the skies seems more likely now than ever. Researchers from Australia have launched a new research program tasked with developing portable brain CT scanners that can be installed onboard aircraft to give rural areas access to faster stroke intervention.  Discuss
AI analysis of FFR-CT shows value -- in men
September 11, 2019 -- An artificial intelligence (AI) algorithm that estimated fractional flow reserve (FFR-CT) on coronary CT angiography outperformed visual stenosis scoring by clinicians for detecting lesion-specific ischemia in men -- but not women, according to research published online September 7 in the European Journal of Radiology.  Discuss
Blood biomarkers bolster CT lung cancer screening
September 9, 2019 -- Adding a blood test to CT lung cancer screening improved the early detection of lung cancer by 36% in an ongoing study and may help lower mortality rates in high-risk smokers, compared with standard clinical care, according to a September 9 presentation at the World Conference on Lung Cancer in Barcelona, Spain.  Discuss
Vaping provokes lung disease in healthy individuals
September 6, 2019 -- Researchers from the U.S. have linked vaping to the development of severe respiratory illnesses identified on CT scans, according to a report published online September 6 in the New England Journal of Medicine. The findings indicate that marketing claims attesting to the safety of vaping with electronic cigarettes may have been misleading.  Discuss
New study links medical imaging radiation to cancer risk
September 5, 2019 -- A nationwide study covering millions of youths in South Korea has substantiated concerns over the health risks of radiation exposure from diagnostic imaging -- linking it to an increased incidence of cancer. The findings are the subject of an article published online September 4 in JAMA Network Open.  Discuss
Cancer deaths eclipse heart disease in developed world
September 4, 2019 -- Cancer is now the leading cause of death in high-income countries, with twice as many people dying from cancer than heart disease in these nations. Heart disease continues to be the main cause of death in less prosperous countries, according to data presented at this week's European Society of Cardiology meeting in Paris.  Discuss
Mobile CT unit boosts efficiency of stroke triage
September 3, 2019 -- Mobile stroke ambulances equipped with a CT scanner and medical personnel can greatly improve the accuracy and efficiency of determining which stroke patients require surgical treatment, compared with standard clinical decision-making, according to a study published online September 3 in JAMA Neurology.  Discuss
Could patient history help predict CT contrast reactions?
September 3, 2019 -- Having a genetic predisposition to allergies could increase an individual's risk of having an adverse reaction to iodine contrast agents, according to an article published online September 3 in Radiology. Identifying these individuals in advance could help prevent unnecessary complications for contrast-enhanced CT.  Discuss
Dual-energy CT differentiates bullets in gunshot wounds
August 30, 2019 -- Dual-energy CT is capable of distinguishing among various types of bullets in gunshot wounds based on their core material, which may have implications for the role radiologists play in forensics, according to an article published in the September issue of the American Journal of Roentgenology.  Discuss
