Testosterone treatment raises levels of heart plaque
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
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
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.

Coronary calcium predicts events, death, in younger adults
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.

Machine-learning analysis of heart motion predicts survival
A machine-learning survival model based on 3D cardiac motion predicts outcomes beyond conventional risk factors in patients with pulmonary hypertension, according to a new study from the U.K. and Singapore. Semiautomated analysis of the cine MR images could potentially be used to guide patient management.

CT lung screening cost-effective with stringent criteria
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.

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.
