Red blood cells likely cause spontaneous echo contrast; leaves open clinical translation pending human validation.
What is the underlying mechanism of spontaneous low-amplitude echoes from blood observed by real-time ultrasound?
Red blood cells are identified as the most likely scattering agent responsible for the spontaneous contrast effect observed clinically in blood vessels during ultrasound.
Wolverson et al. (1981) studied this question.
