What is an advantage of pulsed-wave Doppler over continuous-wave Doppler?

Comprehensive and Detailed Explanation From Exact Extract:

The primary advantage of pulsed-wave Doppler is its ability to provide range resolution. This means the operator can select a specific depth (sample volume) from which Doppler signals are acquired, allowing precise localization of blood flow velocities.

According to sonography instrumentation reference:

“Pulsed-wave Doppler allows for range resolution, enabling velocity measurements at a specific depth along the ultrasound beam path.”

Continuous-wave Doppler does not have range resolution, as it measures velocities along the entire beam path.

Therefore, the correct answer is C: Range resolution.
