1. The use of ultrasound contrast agent should be avoid in the following situation:
1. Severe pulmonary hypertension
2. Acute respiratory distress syndrome
3. Right-to-left cardiac shunts
4. All of the above
2. The typical enhancement pattern of hepatocellular carcinoma on contrast-enhanced ultrasound does NOT include:
1. Hyper-enhancement during arterial phase.
2. Early washout during portal phase.
3. Iso-enhancement during delayed phase.
4. All of the above are typical patterns.
3. The enhancement pattern hemangioma on contrast-enhanced ultrasound does NOT include:
1. Peripheral nodular enhancement during arterial phase.
2. Centripetal fill-in of peripheral enhancement during portal phase.
3. Iso- to hyper-enhancement during delayed phase.
4. All of the above are typical patterns.
4. Which of the following ultrasound contrast agent allows the observation of the hepatocyte phase (Kupffer-phase):
1. Definity(Perflutren microbubbles)
2. Sonazoid (Perflubutane microbubbles)
3. SonoVue (Sulphur hexafluoride microbubbles)
4. None of the above
5. Which of the following is usually hypo-enhanced in later hepatocyte phase (Kupffer-phase) on contrast-enhanced ultrasound:
1. Well-differentiated hepatocellular carcinoma
2. Hepatic hemangioma
3. Focal nodular hyperplasia
4. None of the above
6. What is the component of biliary sludge?
1. Calcium bilirubinate granules
2. Cholesterol crystals
3. Both of the above
4. None of the above
7. What is wrong about characteristics of tumefactive biliary sludge?
1. Low-amplitude echoes
2. Form a fluid-fluid level
3. Appearance of a polypoid mass
4. A smooth margin, round, and lobulated
8. Differential diagnosis for an echogenic mass in GB may include:
1. LGB carcinoma
2. LTumefactive biliary sludge
3. Gangrenous cholecystitis
4. All of the above
9. What is the wrong description about biliary sludge?
1. Essentially an ultrasonographic diagnosis
2. Predominant in GB, is probable a gall stone precursor
3. Common in patients with GB stasis or dysfunction
4. Rare in patient s receiving TPN
10. What is wrong about biliary sludge?
1. Rare in patients with prolonged fasting
2. May play a role in biliary colic & acute pancreatitis
3. Extra-hepatic biliary tract obstruction or hemolysis have a propensity to form & accumulate
4. Changes in positions of patient result in different images
