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