ARDMS ABDOMEN DAVIES QUESTIONS AND
ANSWERS 100% PASS
You are scanning a patient with a known mass in the left medial segment of the liver. What
anatomic landmark can you use to identify the left medial segment separate from the right
anterior segment of the liver? - -Middle Hepatic Vein
Which organ is the largest visceral organ in the body ? - -Liver
Where is the major portion of the liver, the right lobe located? - -in the right upper
quadrant of the abdomen
What organ is covered in large part by the peritoneum , except for a small area posterior to
the dome known as the bare area? - -the Liver
Which organ is covered in a layer of fibrous tissue, glisson's capsule? - -the Liver
You suspect enlargement of the caudate lobe in a patient with 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 a recannalized paraumbilical. Which anatomic
structure is a useful landmark in location of this structure? - -Ligamentum teres
What is the left portal vein in contact with? - -Ligamentum teres
Where does the paraumbilical vein begins? - -begins at the left portal vein and exits
the liver at the ligamentum teres

,2
Which vessel course 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 sonogram on a slender female and notice a long, thin extension of the
inferior aspect of the right lobe of the liver. The most likely represents: - -Reidel's lobe
What forms the caudal border of the left portal vein? - -Ligamentum teres
What ligament divides the left lobe of the liver into medial and lateral segments? - -
Ligamentum teres
You are asked to perform a Doppler study on the hepatic veins in the liver. What
differentiates the hepatic 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 ligamentum venosum. This mass is
located in what lobe of the liver ? - -Left Lobe
The thin capsule surrounding the liver is known as: - -Glisson's capsule
What courses interlobar and intersegmental within the liver? - -Hepatic veins
You are performing an ultrasound exam of the liver on a small patient with 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 with a lower frequency transducer.

Correctly describe the probe placement and imaging plane you would use to demonstrate
the three hepatic veins and inferior vena cava in the one view? - -Subcostal oblique
approach with the probe angled superiorly and to the patient's right.
You are performing a follow-up sonogram on a patient in which a 5 -mm cyst was previously
identified at the anterior border of the left lobe liver. Although you are using a 3.5 MHz
curved linear array probe, you do not see the cyst. What would be most helpful in improving
visibility of this cyst? - -Rescan the left lobe with a higher frequency transducer.
Visibility of small cysts is limited by spatial resolution. To improve spatial resolution, the
best option is to increase the imaging frequency.
What do you need to do to improve spatial resolution to visualize small cysts (which has a
limited spatial resolution)? - -The best option is to increase the imaging frequency
You are imaging a patient with a high liver. Subcostal images do not clearly demonstrate the
liver tissue. What should you do? - -Scan the patient in deep inspiration
A patient is referred for ultrasound evaluation of a questionable mass in the dome of the
liver seen on a CAT scan. What would improve visualization in this area of the liver? -
-Perform a subcostal scan with the probe angled superior and the patient in deep
inspiration
A patient is referred for a liver ultrasound with the clinical history of a raised serum alpha-
fetoprotein level. What should you look for? - -Hepatocellular carcinoma
If a non pregnant person with elevated levels of serum alpha-fetoprotein AFP , what is
associated with this? - -Hepatocellular carcinoma, germ cell tumor of gonadal,
retroperitoneal, or mediastinal origin. Sometimes with cancer of pancreas, stomach, or
biliary system.
