Abdominal US Review
Terms in this set (18)
You were scanning a patient w a known mass in the left medial seg of the liver. What anatomic landmark can you use to identify the left medial seg separate from the right anterior seg of the liver?
middle hepatic vein
You suspect enlargement of the caudate lobe in a patient w liver disease. what structure located at the anterior border of the caudate lobe will help you to identify this lobe of the liver?
fissure for the ligamentum venosum
You are asked to rule out the presence of recannalized paraumbilical. Which anatomic structure is a useful landmark in location of this structure?
which vessel courses within the main lobar fissure?
middle hepatic vein
Oxygenated blood is supplied to the liver via the..
portal vein and hepatic artery
You are performing a US scan on a slender female and notice a long, thin extension of the inferior aspect of the right lobe of the liver. This most likely represents?
What forms the caudal border of the left portal vein?
What ligament divides the left lobe of the liver into medial and lateral segments?
You are asked to perform a Doppler study on the hepatic veins in the liver. What differentiates the veins from the portal veins?
the portal veins are accompanied by branches of the biliary tree and hepatic artery.
You have detected a mass anterior and to the left of the ligamentum venosum. This mass is located in what lobe?
The thin capsule surrounding the liver is known as?
Which of the vein course interlobar and intersegmental within the liver?
You are preforming an US exam of the liver on a small patient w a 5MHz curved linear array. Although you have increased the overall gain to its maximum setting, the posterior border of the liver and diaphragm are not visualized. What should you do?
rescan the liver w a lower freq transducer (lower frequency=more penetration)
Correctly describe the probe placement and imaging plane you would use to demonstrate the 3 hepatic veins and IVC in one view...
subcoastal, oblique approach w the probe angled superiorly and to the patient right.
You are preforming a f/u US on a patient in which a 5mm cyst was previously identified at the anterior border of the left lobe of the liver. Although you are using a 3.5MHz curved linear array prob, you do not see the cyst. What would be most helpful in improving the visibility of this cyst?
rescan the liver w a higher freq transducer (visibility of small cysts is limited by spatial resolution. to improve spatial resolution, the best option is to increase the imaging freq.
You are imaging a patient w a high liver. Subcoastal images do not clearly demonstrate the liver tissue. What should you do?
scan the patient in deep inspiration
A patient is referred for US evaluation of a questionable mass in the dome of the liver seen on a CT scan. What method would improve visualization in this area of the liver?
perform a subcoastal scan w the probe angled superior and the patient in deep inspiration
A patient is referred for a liver US with a clinical history of a raised serum alpha-fetoprotein level. What should you look for?
liver cancer...ie: hepatocellular carcinoma
