What is the purpose of using duplex ultrasound in vascular studies?
Answer: Evaluate blood flow and vessel structure
Duplex ultrasound combines traditional ultrasound and Doppler to visualize vessels and evaluate blood flow.
Which condition is indicated by a monophasic waveform in an arterial ultrasound?
Answer: Arterial occlusion
A monophasic waveform usually suggests a significant downstream obstruction in an artery.
Which parameter is used to quantify arterial stenosis in vascular imaging?
Answer: Peak systolic velocity
Peak systolic velocity (PSV) is often measured to determine the severity of arterial narrowing.
Which vein is commonly assessed for deep vein thrombosis (DVT)?
Answer: Femoral vein
The femoral vein is one of the most commonly evaluated veins in DVT assessments.
What does a high-resistance waveform typically indicate?
Answer: Supply to muscular arteries
High-resistance waveforms are characteristic of arteries supplying muscles or organs with intermittent demand.
Why is patient hydration important before vascular ultrasound exams?
Answer: It enhances venous return and image quality
Hydration improves venous return and may enhance imaging, especially in abdominal vascular studies.
