Describe two methods of Doppler imaging. How do peak velocity parameters relate to the severity of a stenosis? How does one determine a resistive index using Doppler ultrasound? How is Doppler information displayed? How is flow at a stenosis depicted by Doppler? How is flow to an organ different from systemic arterial flow? What happens to the flow at a stenosis? What is aliasing? What is duplex Doppler ultrasound? What is laminar flow? What is the Doppler angle? What is the Doppler effect? What is the optimal Doppler angle? What is the resistive index?
