Colour Doppler Flashcards
1
Q
What is colour doppler?
A
uses the Doppler effect to visualize blood flow within vessels. It provides real-time information about the speed and direction of blood flow, which is displayed as a color-coded map overlaid on a grayscale ultrasound image
2
Q
What is spectral doppler?
A
a type of Doppler ultrasound that provides a graphical representation of blood flow velocities over time. It uses the Doppler effect to measure and display the speed and direction of blood flow within vessels.
3
Q
What is power doppler?
A
an advanced ultrasound technique that visualizes blood flow by displaying the amplitude of the Doppler signal in color, rather than showing the speed and direction of flow
