Testing a new surfactant in a widely-used blood mimic for ultrasound flow imaging

Abstract

It was found that both blood mimics can provide exactly the same images under spectral Doppler ultrasound and colour Doppler ultrasound in terms of their image qualities. The maximum velocities under constant flow were measured by the spectral Doppler ultrasound as 0.4714 ± 0.001 m.s and 0.4644 ± 0.001 m.s for blood-mimicking fluid with Synperonic N and blood-mimicking fluid with Synperonic A7, respectively. Measured velocities using the two different blood-mimicking fluids were statistically different ( < 0.001), but this difference was less than 2%. The Synperonic A7 can be used as a substitute for Synperonic N as a surfactant material in making the blood-mimicking fluid for ultrasound flow imaging research.
