Deltoid Muscle Brightness on Ultrasound May Be Linked With Diabetes

An unusually bright, or hyperechoic, deltoid muscle on ultrasound may be a result of insulin resistance and thus a sign of diabetes, according to a new study. In patients without diabetes, the deltoid is typically hypoechoic relative to the underlying supraspinatus tendon, researchers noted in a presentation November 26 at the Radiological Society of North America (RSNA) 2018 Scientific Assembly and Annual Meeting in Chicago.

AI Outperformed Radiologists In Screening X-rays

In a matter of seconds, a new algorithm read chest X-rays for 14 pathologies, performing as well as radiologists in most cases, a Stanford-led study says. A new artificial intelligence algorithm can reliably screen chest X-rays for more than a dozen types of disease, and it does so in less time than it takes to read this sentence, according to a new study led by Stanford University researchers.

MRI Scans Might Help Predict Dementia Risk

One day, MRI brain scans may help predict whether older people will develop dementia, new research suggests. In a small study, MRI brain scans predicted with 89 percent accuracy who would go on to develop dementia within three years, according to research at Washington University School of Medicine in St. Louis and the University of California San Francisco

World's First Medical Imaging Scanner

EXPLORER, the world's first medical imaging scanner that can capture a 3-D picture of the whole human body at once, has produced its first scans. The brainchild of UC Davis scientists Simon Cherry and Ramsey Badawi, EXPLORER is a combined positron emission tomography (PET) and x-ray computed tomography (CT) scanner that can image the entire body at the same time.
