Sono Appearance

Aorta/IVC sonographic appearance

TermDefinition
The aorta appears as: a tubular structure with anechoic (black) lumen & echogenic (bright) walls; pulses
The proximal aorta is denoted as the portion: ABOVE SMA
The mid aorta is denoted as the portion: BELOW the SMA
The distal aorta is denoted as the portion: just before the bifurcation
To see the celiac artery (seen in transverse): find the SMA & angle superiorly above pancreas
The celiac artery appears as a characteristic: "seagull" sign
In sagittal, the SMA is found: anterior to the aorta & inferior to the celiac
In transverse, the SMA is found: posterior to the pancreas & splenic vein
In transverse, the SMA appears as: a circular structure with an echogenic (bright) ring
What is the MOST helpful image for identification of other structures? Transverse SMA
Renal arteries are best identified in which sonographic plane? Transverse
The right renal artery (RRA) appears as: a circular structure posterior to the longitudinal IVC
How can you tell if you're looking at the IVC as opposed to the aorta? The vessel collapses with respirations; may see internal moving echoes
How can you tell the difference between portal veins & hepatic veins in your image? Portal veins have echogenic walls; Hepatic veins have no visible walls (anechoic)
What do you use to view the proximal IVC? the liver
Distal IVC can be difficult to see due to: bowel gas
