Elevated CT CAC scores linked to future heart failure
June 14, 2019 -- The presence of coronary artery calcium (CAC) on the CT scans of middle-aged individuals, especially African Americans, was associated with an increased risk of structural heart abnormalities and future heart failure in a new study, published online June 14 in Circulation: Cardiovascular Imaging.  Discuss
CT lung screening reduces cancer mortality most in women
June 14, 2019 -- CT lung cancer screening reduced cancer mortality by 69% in high-risk female smokers in the German Lung Cancer Screening Intervention trial, based on new results. But the test offered less of a benefit to men, according to a study recently published in the International Journal of Cancer.  Discuss
FFR-CT beats CCTA for assessing heart disease outcomes
June 12, 2019 -- Fractional flow reserve CT (FFR-CT) was significantly better at predicting the long-term effects of cardiac disease -- including death, heart attack, and the need for revascularization -- than conventional coronary CT angiography (CCTA) in a new study, published online June 11 in Radiology.  Discuss
AI converts low-dose CT scans to high-quality studies
June 12, 2019 -- An artificial intelligence (AI) algorithm can transform low-dose CT (LDCT) scans into high-quality exams that radiologists may even prefer over LDCT studies produced via commercial iterative reconstruction techniques, according to research published online June 10 in Nature Machine Intelligence.  Discuss
Risk models boost efficiency of CT lung cancer screening
June 4, 2019 -- Integrating risk-prediction models into eligibility criteria for CT lung cancer screening could prevent up to 24% more cancer deaths than using guidelines from the U.S. Preventive Services Task Force, with no difference in the number of smokers screened, according to a report published June 3 in the Annals of Internal Medicine.  Discuss
Is whole-body CT necessary after motor vehicle crashes?
May 30, 2019 -- Using whole-body CT to evaluate patients with normal physical presentation following a motor vehicle crash did not prompt any changes in their medical care in a new study, published online May 28 in Radiology. The findings question the value of the imaging technique in some emergency trauma cases.  Discuss
3 ways to lower CT radiation dose across the hospital
May 24, 2019 -- A hospital-wide quality improvement project effectively lowered CT radiation dose by nearly 20%, report researchers from Seattle. They detailed how three initiatives enabled them to achieve this dose reduction in an article published online May 21 in the Journal of the American College of Radiology.  Discuss
CT lung screening risk model cuts false-positive rate
May 23, 2019 -- Using a risk prediction model to figure out which nodules to work up helped reduce the false-positive rate in a CT lung cancer screening trial by more than threefold, compared with rates using previous criteria, according to an article published online May 15 in the Journal of the American College of Radiology.  Discuss
Medicaid expansion boosted cancer screening rates
May 22, 2019 -- The five states and the District of Columbia that expanded their Medicaid coverage after the Patient Protection and Affordable Care Act of 2010 first went into effect showed larger increases in cancer screening rates than states that did not, according to a study published online May 22 in the American Journal of Preventive Medicine.  Discuss
Google AI accurately assesses CT lung screening scans
May 22, 2019 -- An artificial intelligence (AI) model developed by Google can assess cancer risk on CT lung cancer screening studies as well as, or even better than, experienced radiologists -- potentially enabling automated evaluation of these exams, according to research published online March 20 in Nature Medicine.  Discuss
