Identify the phase & direction of flow at point A

Systole- forward flow

Identify the phase & direction of flow at point B

What pathology is being shown in this image?

Stenosis

What Doppler feature is demonstrated in the spectral waveform?

Spectral broadening indicating disturbed/turbulent flow

Based on the Doppler image, which finding best characterizes the hemodynamics at the sampled site?

Focal flow acceleration with spectral broadening consistent with a stenotic jet

Elevated velocities associated with this finding may be detected:

Within the stenosis and extending into adjacent proximal and distal segments

Which combination of Doppler findings most strongly supports hemodynamically significant stenosis in this image?

Elevated peak velocities with spectral broadening and evidence of flow disturbance

The Doppler sample volume in this image is most likely located:

Distal to a stenosis

Identify TWO abnormal Doppler findings present in this image.

Spectral broadening + turbulent/chaotic flow with eddy currents
