NLST update: CT sees twice the lung cancers of x-ray May 23, 2013 -- A new analysis of data from the landmark 2011 National Lung Screening Trial (NLST) found that low-dose CT detected twice as many early-stage lung cancers as x-ray on initial screening, cementing CT's promise as a tool that can reduce lung cancer mortality by 20% or more, according to results published in the New England Journal of Medicine.
BMJ: Megastudy links pediatric CT to higher cancer rates May 23, 2013 -- The largest study to probe the effects of ionizing radiation since the atomic bomb survivor studies shows that cancer incidence does rise among younger patients -- although only in small amounts -- in the years following their exposure to CT scans, according to an Australian article published May 21 in BMJ.
ATS: VA lung cancer study embraces broader screening criteria May 21, 2013 -- A small CT lung cancer screening study of U.S. veterans found a higher rate of disease compared to the landmark National Lung Screening Trial, according to results presented at this week's American Thoracic Society (ATS) meeting in Philadelphia. The higher prevalence could fuel debate surrounding the criteria for patient selection.
CAD helps detect and treat skull fusion in infants May 20, 2013 -- Computer-aided detection (CAD) technology can be an invaluable tool for quantitative diagnosis and treatment planning of craniosynostosis, or premature fusion of skull sutures in infants, researchers from Children's National Medical Center in Washington, DC, have found.
4D musculoskeletal CT offers window into joint disorders May 17, 2013 -- There's still a lot to learn about how bones interact in joints during movement, but 4D musculoskeletal CT can help close that knowledge gap, paving the way for new understanding of joint disorders and how to treat them, according to researchers from Monash Health Centre in Melbourne, Australia.
A radiologist reflects on the Boston Marathon bombings May 16, 2013 -- Monday, April 15 -- Patriots' Day in Boston -- started much like any other day for radiologist Dr. Robert Ward of Tufts Medical Center. But it turned out to be anything but normal after two bombs exploded at the end of the Boston Marathon, sending dozens of injured people to Tufts with battlefield-like injuries.
Technologists' CT training called woefully inadequate May 15, 2013 -- CT might be the mainstay of medical imaging, but the basic curriculum for radiologic technologist training hardly mentions the modality, and training centers that do teach it are few and far between, according to a talk on May 10 at the Virtual Symposium on Radiation Safety and Computed Tomography.
CCTA for chest pain cuts costs, admissions May 14, 2013 -- One of the largest studies yet comparing medical resource use and outcomes among chest pain patients found that coronary CT angiography (CCTA) reduced medical resource utilization compared to standard care, generating fewer hospital admissions and shorter emergency room stays, researchers reported in the Journal of the American College of Cardiology.
ACCP recommends lung cancer screening with CT May 7, 2013 -- The American College of Chest Physicians (ACCP) today recommended lung cancer screening with low-dose CT for patients at high risk of the disease. But the new guidelines closely follow more conservative recommendations for screening.
AATS: Low-dose CT outruns x-ray for lung cancer surveillance May 6, 2013 -- In a study of more than 300 patients undergoing surveillance after lung cancer surgery, ultralow-dose CT far outperformed chest radiography for detecting cancer recurrence, concluded a study presented this week at the 2013 American Association for Thoracic Surgery (AATS) meeting in Minneapolis.
