Sep 25, 2023 · Hyperechoic areas are often white or light gray, indicating that the structure reflects more sound waves than surrounding tissues. The terms isoechoic and hypoechoic describe a nodule’s brightness relative to the adjacent normal thyroid parenchyma. nlm. Hypoechoic areas appear darker because they reflect fewer sound waves, while hyperechoic areas appear brighter due to stronger echoes. Understanding the difference between hyperechoic and hypoechoic is important for accurately interpreting ultrasound images. Checking your browser before accessing pmc.
