What are some examples of Doppler characteristics?

What causes Phasicity of blood flow?

Process of recurring cycles

What are the causes of cyclical pressure fluctuations?

Demonstrates velocity and acceleration fluctuations. Generally cyclical in appearance.

Pulsation, phasic flow pattern secondary to proximity to the right atrium.

What does flow in the hepatic veins reflect?

Hepatic vein pulsatility is partially transmitted to the ______ through the ______

What happens as the hepatic veins empty into the IVC/ RA

An indicator of resistance to perfusion

What does Doppler spectral analysis reveal?

Systolic- diastolic/ systolic

Flow during systole, flow only when the heart is pumping

Flow during systole and diastole, flow when the heart is pumping and when at rest.

Visceral vessels that feed our organs

What is a normal aortic Doppler?

What are the aortic branches?

What does the celiac axis looks like in 2D?

What does the waveform for the celiac axis look like?

Arises from the celiac axis, and courses to the right towards the liver.

What does the waveform look like in the hepatic artery?

What two arteries arise from the celiac axis?

Arises from celiac axis, courses to the left toward the spleen

Is the splenic artery very tortuous?

What does the waveform for a splenic artery look like?

Courses parallel and anterior to the aorta, and surrounded by an echogenic ring.

The SMA has 2 different wave forms what are they?

The bowel is not actively needed, so blood flow is not on high demand, high resistant with minimal diastolic flow

The bowel is active during digestion, so blood is needed, resulting in a low resistant waveform

Branch from the lateral aspect of the aorta

What should the waveform look like for the renal arteries?

Branch from the aorta, low resistant

Anechoic, courses through liver posterior to the left lobe, diameter fluctuations

What are the normal Doppler characteristics for the IVC?
