Cyclic changes of blood echogenicity in high-frequency ultrasound
Ultrasound in Medicine & Biology , Volume 17 - Issue 7 p. 723- 728
Ultrasound images from human arteries obtained in vivo with an intravascular 30 MHz ultrasound imaging device show that blood echogenicity changes during the cardiac cycle. Quantitative measurements of blood echogenicity during the cardiac cycle suggest that these variations may be related to changes in the state of erythrocyte aggregation, which are induced by varying shear rate.
