X A protocol is not specified for images in Color Doppler Mode or Power Doppler Mode. Therefore, the same limitations imposed when measurements are taken in B/W images apply to the accuracy of the measurements taken in these modes.
XIt is not recommended to use images in Color/Power Doppler Mode for measurement of accurate blood flow velocity.
XThe amount of blood flow is calculated based on the average velocity rather than the peak velocity.
XIn all applications, the amount of blood flow is measured in PW Spectral Doppler Mode.
