What is echogenic sludge?

Echogenic sludge refers to a collection of particulate matter and fluid that appears bright or reflective on ultrasound imaging, indicating a dense or thick composition. It is often found in the gallbladder and can be associated with conditions like biliary stasis or inflammation. The presence of echogenic sludge may suggest an underlying pathology, such as gallstones or cholecystitis, warranting further evaluation. Its characteristics help radiologists assess the potential need for intervention or treatment.
