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? correct answers Middle Hepatic Vein
Which organ is the largest visceral organ in the body ? correct answers Liver
Where is the major portion of the liver, the right lobe located? correct answers 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? correct answers the Liver
Which organ is covered in a layer of fibrous tissue, glisson's capsule? correct answers 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?
correct answers 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? correct answers Ligamentum teres
What is the left portal vein in contact with? correct answers Ligamentum teres
Where does the paraumbilical vein begins? correct answers begins at the left portal vein and
exits the liver at the ligamentum teres
Which vessel course within the main lobar fissure? correct answers middle hepatic vein
Oxygenated blood is supplied to the liver via the: correct answers 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: correct answers Reidel's
lobe
What forms the caudal border of the left portal vein? correct answers Ligamentum teres
What ligament divides the left lobe of the liver into medial and lateral segments? correct answers
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? correct answers 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 ? correct answers Left Lobe
The thin capsule surrounding the liver is known as: correct answers Glisson's capsule
What courses interlobar and intersegmental within the liver? correct answers 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? correct answers
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? correct answers 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? correct answers 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)? correct answers 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? correct answers 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? correct answers
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? correct answers Hepatocellular carcinoma
If a non pregnant person with elevated levels of serum alpha-fetoprotein AFP , what is associated

or mediastinal origin. Sometimes with cancer of pancreas, stomach, or biliary system.
What may produce modest serum AFP elevations? correct answers Hepatitis and cirrhosis
, You are reviewing lab work prior to performing an abnormal ultrasound exam. Elevated lab
values include Gamma- glutamyl transpeptidase -GGT and alkaline phosphatase. What would it
be? correct answers Concomitant elevation of both GGT and alkaline phosphate indicates the
source of the elevated alkaline phosphatase is the liver.
what other reasons would alkaline phosphatase be elevated ? correct answers skeletal disease,
hyperparathyroidism, and acute hepatocellular disease
What is NOT a lab test use in evaluation of liver function out of the following GGT, AST, direct
bilirubin, indirect bilirubin, or lipase? correct answers Lipase - is used to evaluate acute
pancreatitis
What does it mean when direct bilirubin is elevated? correct answers usually indicates biliary
obstruction, which may be intrahepatic due to hepatitis, cirrhosis, or extrahepatic due to
gallstones, gallbladder or pancreatic cancer.
Why would indirect bilirubin be elevated? correct answers with hepatocellular dysfunction such
as hepatitis
What is Aspartate aminotransferase - AST used in evaluating? correct answers used in evaluation
of acute hepatic disease. May also be elevated with recent myocardial infarction.
What is Gamma- glutamyl transpeptidase - GGT is used with what to suggest the source of
elevated alkaline phosphatase levels? correct answers used with alkaline phosphatase
A patient is referred with right upper quadrant tenderness and a history of oral contraceptive use.
A solid, hypoechoic mass is identified in the right lobe of the liver. Color Doppler reveals
hypervascularity of the mass. What is the scenario likely to be? correct answers Hepatic
Adenoma - the incidence of hepatic adenomas has increased in the united states since the 1970s.
And are associated with use of oral contraceptives.
A liver ultrasound on a 49-year-old obese male demonstrates diffuse increased echogenicity with
a focal hypoechoic area anterior to the portal vein. This most likely represents: correct answers
Fatty metamorphosis of the liver with focal sparing
What is commonly seen as a hypoechoic mass anterior to the portal vein? correct answers Focal
fatty sparring
A 52-year-old male with known liver cirrhosis presents for an abdominal ultrasound. You will
carefully evaluate the liver to rule out the presence of any focal mass because of what? correct
answers Patients with liver cirrhosis are at increased risk for hepatocellular carcinoma
You are scanning a patient with suspected liver cirrhosis. All of the following, 1. Surface
nodularity, 2. Shrunken caudate lobe, 3. Altered echo texture, 4. Ascites, 5. Regenerative nodules
are sonographic feature of cirrhosis Except: correct answers Shrunken caudate lobe
