OAK BROOK, Ill. - A machine learning algorithm helps accurately differentiate benign and premalignant colorectal polyps on CT colonography scans, according to a study published in the journal
Radiology.
Colorectal cancer is among the three most common causes of cancer-related death among men and women in industrialized countries. Most types of colorectal cancer originate from adenomatous polyps gland-like growths on the mucous membrane lining the large intestine that develop over several years. Early detection and removal of these precancerous polyps can reduce the incidence and mortality of colorectal cancer.

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
Radiology. Researchers said the study shows the power of radiomics to improve understanding of not just cardiovascular disease, but cancer and other conditions as well.
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.
Researchers using MRI have found significant abnormalities in the eyes of some people with severe COVID-19, according to a new study. The study results support the need for eye screening in these patients to provide appropriate treatment and management of potentially severe ophthalmological manifestations of COVID-19.

OAK BROOK, Ill. - Breast cancer death rates have stopped declining for women in the U.S. younger than age 40, ending a trend that existed from 1987 to 2010, according to a new study in
Radiology. Researchers expressed hope that the findings would raise awareness of breast cancer in younger women and spur research into the causes behind the change.
Breast cancer is the most common non-skin cancer and the second most common cause of cancer deaths in women in the U.S., accounting for 30% of all cancers in women. Although most invasive breast cancers occur in women age 40 years and older, 4% to 5% of cases happen in women younger than 40 years.
