July 20, 2018 -- Following its recent release of a massive database of chest x-rays, the U.S. National Institutes of Health (NIH) has now made nearly 10,600 CT scans publicly available to support the development and testing of artificial intelligence (AI) algorithms for medical applications.  Discuss
CT scans may be linked to brain cancer in kids
July 20, 2018 -- Could exposure to CT radiation increase the risk of brain tumors in kids? Yes, say researchers from the Netherlands, who reported a 1.5-fold increase in cancer incidence for children in an article published online July 18 in the Journal of the National Cancer Institute.  Discuss
CCTA biomarker spots high-risk plaques in heart disease
July 18, 2018 -- An increase in pericoronary adipose tissue attenuation -- a biomarker associated with inflammation -- on coronary CT angiography (CCTA) scans was associated with vulnerable plaques and may help predict the risk of heart disease, according to an article published online July 18 in JAMA Cardiology.  Discuss
New Zealand start-up scans 1st humans with spectral CT
July 18, 2018 -- Researchers from a start-up company in New Zealand have scanned the first humans with a spectral CT scanner based on solid-state digital detectors. The technology produces color images at much higher levels of resolution than traditional CT scanners and, thus, may improve diagnosis.  Discuss
Tariffs could add $400M to medical equipment costs
July 13, 2018 -- A new study by a policy institute estimates that the Trump administration's tariffs on products made in China will add $400 million annually to the cost of medical equipment in the U.S. The tariffs will add $44.6 million to the cost of x-ray parts and $33.7 million to the cost of CT scanners.  Discuss
More CT screening may be needed for high-risk smokers
July 12, 2018 -- A few annual rounds of negative CT screening exams might not be enough to rule out lung cancer in the long term, according to an article published online July 10 in Radiology. A group from Canada found a high incidence of early-stage cancer in high-risk individuals several years after the conclusion of initial screening.  Discuss
4 reasons why people seek CT lung cancer screening
July 11, 2018 -- CT lung cancer screening rates have fallen short of expectations, but many eligible people are still seeking out screening. A group out of Washington identified four main factors that motivate individuals to pursue CT screening in an article published online July 5 in PLOS One.  Discuss
USPSTF dismisses CAC for heart disease risk assessment
July 10, 2018 -- The U.S. Preventive Services Task Force (USPSTF) has reaffirmed its recommendation against using nontraditional factors -- including coronary artery calcium (CAC) score -- to assess the risk of heart disease, in a statement published online July 10 in the Journal of the American Medical Association.  Discuss
U.S.-China trade war breaks out as tariffs kick in
July 6, 2018 -- The U.S. slapped tariffs on a wide range of goods imported from China -- including medical imaging scanners -- on Friday, July 6, as the U.S. and China were unable to resolve their differences on trade policy. China has retaliated with tariffs of its own on U.S. products.  Discuss
Variation in emergency CT use may be lower than it seems
July 6, 2018 -- The use of CT in the emergency setting might not vary quite as much as initially reported, according to an article published online July 5 in the American Journal of Roentgenology. Researchers found that taking into account hundreds of factors revealed much lower variability.  Discuss
