Bright deltoid muscle on ultrasound may reveal diabetes

Researcher says radiologists 'have been seeing this for years.'

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.
