US elastography for liver evaluation: Worth the cost?

By Kate Madden Yee

Ultrasound elastography is a relatively new technology that can noninvasively assess liver stiffness, a key component when evaluating the severity of liver fibrosis. But because insurer coverage tends to be variable, it's not in mainstream clinical use, according to a study in the November issue of the Journal of the American College of Radiology.

Artificial intelligence may help bridge experience gap for liver CEUS

By Erik L. Ridley

Can a computer-aided diagnosis system based on machine learning characterize focal liver lesions on contrast-enhanced ultrasound (CEUS) cine clips as accurately as an expert reader? It's certainly possible, if research published online recently in Radiology is any indication.

Canadian task force shifts gears on AAA screening

By Erik L. Ridley

Ultrasound screening for abdominal aortic aneurysms (AAA) may see an uptick in Canada following new guidelines published September 11 by the Canadian Task Force on Preventive Health Care. For the first time, the task force is recommending ultrasound screening, advising a one-time exam for men ages 65 to 80.

USPSTF to take another look at AAA screening

By Erik L. Ridley

Will the U.S. Preventive Services Task Force (USPSTF) change its recommendations for abdominal aortic aneurysm (AAA) screening? It's too early to tell, but the task force published a draft research plan on August 10 to share its vision for how it will reassess the benefits and harms of ultrasound screening.
