OAK BROOK, Ill. - Radiomics the extraction of very detailed quantitative features from medical images provides a refined understanding of how cocaine use and other risk factors affect the course of coronary artery disease, according to a study published in

Coronary artery disease typically develops over time as plaque builds up inside the arteries. This process, known as atherosclerosis, can eventually lead to life-threatening events like heart attack and stroke.
Historically, imaging techniques like coronary CT angiography provided information on atherosclerosis by describing the degree of stenosis, or narrowing, in the coronary arteries. While measures of stenosis are useful, they are not always the most precise way to assess the risk of an adverse event like a heart attack.
