ACC: Study promotes routine PET/CT CAC for cardiac risk
By Abraham Kim
Should coronary artery calcium (CAC) scoring be a routine part of PET/CT stress testing for assessing an individual's risk of heart disease? Yes, according to researchers from Utah who explained why in a Saturday presentation at the American College of Cardiology (ACC) 2019 meeting in New Orleans.

Cardiac risk grows with higher coronary calcium scores
By Abraham Kim
Individuals with high CT coronary artery calcium scores -- at least 1,000 Agatston units -- had a substantially greater risk of all-cause mortality than those with lower scores and nearly triple the risk of those with a score of 0, according to research published online March 15 in JACC: Cardiovascular Imaging.

Lung ultrasound beats chest x-ray for heart failure detection
By Brian Casey
Point-of-care lung ultrasound has a higher sensitivity than chest x-ray for detecting symptoms of pulmonary edema in patients with acute decompensated heart failure, according to a new meta-analysis. The findings could indicate that ultrasound is a better choice for these patients, according to a study published March 15 in JAMA Network Open.

Out-of-pocket costs keep women from mammo follow-up
By Kate Madden Yee
U.S. women who have a suspicious finding from a screening mammogram are delaying -- or even skipping altogether -- needed diagnostic exams because of high out-of-pocket costs, according to a study by the Susan G. Komen breast cancer organization.

Automated algorithms track adherence to follow-up advice
By Erik L. Ridley
An algorithm based on natural language processing was able to analyze radiology reports for text that recommended follow-up imaging, while a second algorithm determined whether patients followed the recommendations, according to an article published online March 12 in the American Journal of Roentgenology.

AI may help women with ductal hyperplasia avoid surgery
By Kate Madden Yee
New York City researchers found that an artificial intelligence (AI) algorithm that analyzed mammography data was able to help determine which patients with pure atypical ductal hyperplasia may safely be monitored with imaging rather than proceed to surgical excision, according to a study published online March 12 in the American Journal of Roentgenology.

Risk prediction model boosts accuracy of CT lung screening
By Abraham Kim
Researchers from the University of Pittsburgh developed a statistical model that combined data from CT scans with patient demographic information to predict an individual's risk of lung cancer on CT lung screening exams. The model worked better than several more-established methods, according to an article published online March 12 in Thorax.

2 new PET tracers may best FDG in cancer imaging
By Wayne Forrest
Cancer detection could receive a boost from two new radiotracers that have achieved substantially shorter image acquisition times than FDG-PET scans and required no fasting or dietary changes, according to a proof-of-concept study published in the March issue of the Journal of Nuclear Medicine.
