CT lung screening spots cancers earlier in China
December 20, 2018 -- A large-scale CT lung screening program in China detected a higher proportion of early-stage lung cancers than did comparable trials in the U.S. and Europe, even for a population that included relatively young, nonsmoking adults, according to an article recently published online in Academic Radiology.  Discuss
CCTA reveals statins may lower mortality in low-risk CAD
December 18, 2018 -- Statin therapy can help mitigate the risk of death in patients with nonobstructive coronary artery disease (CAD), even in those with the lowest levels of calcium and atherosclerosis evident on coronary CT angiography (CCTA) scans, according to an article recently published online in PLOS One.  Discuss
CT lung screening cuts cancer mortality 51% in Japan
December 14, 2018 -- In a new large-scale trial of CT lung cancer screening, researchers are reporting that screening reduced the risk of lung cancer mortality by 51% compared with x-ray screening in a Japanese population that included low-risk individuals and nonsmokers. Their findings were published online December 12 in the Japanese Journal of Clinical Oncology.  Discuss
Mental illness may double need for CT lung screening
December 11, 2018 -- U.S. patients with a mental health illness have a considerably higher smoking prevalence and are nearly two times as likely to be eligible for CT lung cancer screening than individuals without a mental illness, according to a presentation at the recent RSNA 2018 meeting in Chicago.  Discuss
AI algorithm detects all intracranial hemorrhage types
December 6, 2018 -- An artificial intelligence (AI) algorithm can detect all types of intracranial hemorrhage on noncontrast head CT studies, showing potential for use in all clinical scenarios that involve detecting and tracking this critical condition, according to research presented at the recent RSNA 2018 meeting in Chicago.  Discuss
AI reliably characterizes pulmonary nodules on CT
November 28, 2018 -- CHICAGO - An artificial intelligence (AI) algorithm can outperform radiologists in stratifying the risk of pulmonary nodules found on low-dose CT lung screening exams, potentially helping to detect cancer earlier and reduce unnecessary workups, according to research presented on Wednesday at the RSNA meeting.  Discuss
Emergency CT use continues its exponential growth
November 28, 2018 -- CHICAGO - The utilization rate of CT continues to soar in U.S. hospital emergency departments, with radiologists interpreting the majority of these exams. What does the trend say about the state of emergent CT? Researchers from Pennsylvania explored the question in a Tuesday presentation at RSNA 2018.  Discuss

November 27, 2018 -- CHICAGO - GE Healthcare is launching a new artificial intelligence (AI) platform called Edison at this week's RSNA 2018 meeting. Other major product launches include a new CT scanner family, a new series of nuclear medicine systems, and workflow tools for MRI, x-ray, and other modalities.  Discuss
CT-guided pulsed radiofrequency provides back pain relief
November 27, 2018 -- CT-guided pulsed radiofrequency, which applies pulses of energy directly to nerve roots, may be an effective method for alleviating lower back pain for cases when more conservative treatment options fail to do so, according to a Tuesday presentation at RSNA 2018 in Chicago.  Discuss
