Which of the following correctly describes a CW Doppler
evaluation?
A: CW Doppler transducers contain a single element to constantly
transmit sound.
B: CW Doppler tracings will not demonstrate a spectral window.
,UUR SPI Exam 4 Questions And Answers
C: CW Doppler is most useful with low velocity flow that is
undetectable on PW Doppler systems.
D: the angle of the incidence does not affect the velocity evaluation
using CW Doppler because you are not evaluating the vessel at a
specific depth. -
correct answer ✅B: CW Doppler tracings will not demonstrate a
spectral window.
