Does color-coded Doppler ultrasonography improve the accuracy of quantitative blood flow measurements compared to conventional Doppler in an in vitro model?
In vitro testing reveals that both conventional and color-coded Doppler ultrasound systems are subject to wide measurement errors when using hand-held transducers, highlighting the need for methodological adjustments like using maximal values.
