Testosterone treatment raises levels of heart plaque
February 22, 2017 -- A new study using coronary CT angiography reveals that testosterone treatments may increase the risk of heart disease by raising the volume of arterial plaque by 20% among men 65 years and older. More research is needed to assess actual risk, according to a February 21 paper in the Journal of the American Medical Association.
BMJ: Benefits of CT lung cancer screening outweigh dose
February 16, 2017 -- Despite the risks of ionizing radiation from CT lung cancer screening, cumulative exposure over a decade remains very low, along with the risk of developing cancer from screening. The benefits of lung screening thus outweigh any potential harms from radiation, concluded Italian researchers writing February 8 in BMJ.
CT better than echo for aortic annulus before TAVR
February 13, 2017 -- Aortic valve replacement may be more accurate when measurements are made with CT versus echocardiography, according to a January 24 paper in Academic Radiology. Coronary CT angiography measurements correlated well with 3D echocardiography results by most measures, making CT a suitable replacement for echo in planning transcatheter aortic valve replacement (TAVR) surgery.
Official launch of ArabSafe goes ahead
February 10, 2017 -- DUBAI - The first ArabSafe committee meeting was held during Arab Health 2017. Modeled on the EuroSafe Imaging campaign, the new initiative aims to establish a radiation safety culture among Arabic-speaking countries and to ensure the appropriate use of radiation.
Coronary calcium predicts events, death, in younger adults
February 9, 2017 -- If CT scans detect any amount of coronary artery calcium in people between the ages of 32 and 46 years, they have an exponentially higher risk of cardiovascular events and death later in life, according to a February 8 paper in JAMA Cardiology. Developing a screening strategy for younger people at risk should be a priority.
CT lung screening cost-effective with stringent criteria
February 7, 2017 -- Restricting eligibility for CT lung cancer screening to the heaviest smokers would make the exam more cost-effective on a population basis, according to a study published February 7 in PLOS Medicine.
Smokers not picking up the CT lung screening habit
February 2, 2017 -- Low-dose CT lung cancer screening may be reimbursed by insurance now, but you'd hardly know it by the low numbers of high-risk smokers taking advantage of it, according to a February 2 research letter in JAMA Oncology.
CT lung screening enters pipeline in Middle East
February 2, 2017 -- DUBAI - The Abu Dhabi guidelines for CT lung cancer screening were the subject of much debate at the thoracic imaging session during the Total Radiology conference at Arab Health 2017. The guidelines cover an unusual risk factor: 20-year history of water pipe (or shisha) use.
CT lung cancer screening is complicated for VA patients
January 30, 2017 -- For U.S. Veterans Affairs (VA) patients at high risk for lung cancer, CT screening is a "complex endeavor" that turns up multiple comorbidities and introduces potential harms and increased costs, concludes a new study published online January 30 in JAMA Internal Medicine.
CT lung screening finds cancer in nonsmokers
January 12, 2017 -- High-risk nonsmokers have lung cancer at rates comparable to those of smokers in the National Lung Screening Trial, according to a multicenter lung cancer screening trial in Taiwan. If replicated, the results could affect the question of who needs CT lung cancer screening, particularly regarding individuals exposed to secondhand smoke.
