ARDMS Abdomen Exam Questions And Answers (Verified And Updated)

ARDMS Abdomen Exam Questions And Answers (Verified And Updated) 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 from the right anterior segment of the liver? - answerMiddle Hepatic Vein 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 identify this lobe of the liver? - answerFissure 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? - answerLigamentum Teres *The left portal vein is in contact with the ligamentum teres. A paraumbilical vein begins at the left portal vein and exits the liver at the ligamentum teres. Which vessel courses within the main lobar fissure? - answerMiddle Hepatic Vein Oxygenated blood is supplied to the liver via the: - answerPortal 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. This most likely represents: - answerReidel's lobe Which of the following forms the caudal border of the left portal vein? A. Ligamentum venosum B. Hepatoduodenal ligament C. Main Lobar Fissure D. Coronary Ligament E. Ligamentum teres - answerLigamentum teres What ligament divides the left lobe of the liver into medial and lateral segments? - answerLigamentum 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? - answerThe 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 of the liver? - answerLeft Lobe of the Liver The thin capsule surrounding the liver is known as: - answerGlisson's capsule Which of the following course interlobar and intersegmental within the liver? A. Bile ducts B. Portal veins C. Hepatic arteries D. Lymphatics E. Hepatic veins - answerE. Hepatic Veins You are performing an ultrasound exam of the liver on a small patient with a 5 MHz 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? - answerRescan the liver with a lower frequency transducer *Lower frequency transducers provide greater penetration than higher frequency transducers. Another way to increase the penetration is to increase the transmit power. Decreasing the transmit power will decrease penetration. Moving the focal zone into the near field will not improve penetration. How would you correctly describe the probe placement and imaging plane you would use to demonstrate the 3 hepatic veins and IVC in one view? - answerSubcostal oblique approach with the probe angled superiorly and to the patients right You are performing a follow-up sonogram on a patient in which a 5-mm cyst was previously identified at the anterior border if the left lobe of the liver. Although you are using a 3.5 MHz curved linear array transducer, you do not see the cyst. What would be most helpful in improving the visibility of this cyst? - answerRescan the left lobe with a higher frequency transducer *Visibility of small cysts is limited by spatial resolution. To improve resolution, the best option is to increase the imaging frequency.
