AI can improve reproducibility of radiomics in CT
By Erik L. Ridley
An artificial intelligence (AI) algorithm may be able to help overcome one of the biggest issues limiting the clinical use of radiomics in CT -- the low reproducibility of quantitative imaging features on images from different reconstruction algorithms, according to research published online June 18 in Radiology.

Lowering tube voltage slashes CCTA radiation dose
By Abraham Kim
Radiation dose for coronary CT angiography (CCTA) exams can be reduced by as much as 68% -- without hindering diagnostic image quality -- simply by lowering the tube voltage, according to the findings of a multicenter study recently published online in JACC: Cardiovascular Imaging.

CT lung screening reduces cancer mortality most in women
By Abraham Kim
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.

FFR-CT beats CCTA for assessing heart disease outcomes
By Abraham Kim
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.
