Does color velocity imaging accurately estimate flow velocity compared to spectral Doppler in an in vitro phantom model?
Effect estimate: r2 = 0.9979
In vitro testing demonstrates that color velocity imaging is an accurate non-Doppler ultrasound technique for estimating flow velocity, performing comparably to spectral Doppler.
Eicke et al. (1993) studied this question. Color velocity imaging (CVI) vs. Duplex Doppler spectral analysis was evaluated on Relationship between estimated and actual string velocities (r2 = 0.9979). Color velocity imaging yielded highly valid velocity estimates compared to actual string velocities (r2 = 0.9979), demonstrating accuracy comparable to Doppler spectral analysis in vitro.
