Doppler

What type of waveform is represented in this image?

• Triphasic

• Biphasic

• Monophasic

A high resistant waveform is seen in an artery feeding an organ.

• True

• False

A monophasic waveform is indicative of disease.

• True

• False

What exams utilize Doppler?

• An ABI

• Duplex imaging

• Both

• Neither

What does Doppler analyze?

• All of the above

• Speed of blood flow

• Characteristics of blood flow

• Direction of flow

When using pulsed wave Doppler, you want the angle to be set at 65 degrees.

• True

• False

Does this image demonstrate biphasic or triphasic flow?

• Triphasic

• Biphasic

Does duplex imaging use PW (pulsed wave) or CW (continuous wave) Doppler?

• (PW) Pulsed wave

• (CW) Continuous wave

At what angle does no Doppler shift occur?

• 15°

• 90°

• 120°

• 0°

Antegrade flow appears below the baseline.

• True

• False
