Sono Appearance
Aorta/IVC sonographic appearance
Term | Definition |
---|---|
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 |
