General Imaging

Hyperechoic

In general imaging, “hyperechoic” describes tissues that appear brighter than surrounding structures on an ultrasound image, indicating they reflect more sound waves. This high echogenicity is often seen in dense tissues like bone, gallstones, or highly fatty lesions, due to their strong impedance mismatch with adjacent areas. Understanding hyperechoic findings is crucial for accurate ultrasound diagnosis, helping differentiate normal anatomy from pathologies. Search terms: hyperechoic ultrasound, general imaging, echogenicity, bright on ultrasound.
