CVT Vascular Technology & Hemodynamics 1

Question 1

What is the purpose of using duplex ultrasound in vascular studies?

Accepted Answer

Evaluate blood flow and vessel structure

Answer

Duplex ultrasound combines traditional ultrasound and Doppler to visualize vessels and evaluate blood flow.

Question 2

Which condition is indicated by a monophasic waveform in an arterial ultrasound?

Accepted Answer

Arterial occlusion

Answer

A monophasic waveform usually suggests a significant downstream obstruction in an artery.

Question 3

Which parameter is used to quantify arterial stenosis in vascular imaging?

Accepted Answer

Peak systolic velocity

Answer

Peak systolic velocity (PSV) is often measured to determine the severity of arterial narrowing.

Question 4

Which vein is commonly assessed for deep vein thrombosis (DVT)?

Accepted Answer

Femoral vein

Answer

The femoral vein is one of the most commonly evaluated veins in DVT assessments.

Question 5

What does a high-resistance waveform typically indicate?

Accepted Answer

Supply to muscular arteries

Answer

High-resistance waveforms are characteristic of arteries supplying muscles or organs with intermittent demand.
