Radiology · Ultrasound: elastography

Sample item

A transient elastography (FibroScan) measurement of the liver is used to assess which property?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Liver stiffness as a marker of fibrosis

Transient elastography sends a mechanical pulse and measures the shear wave speed, which rises with stiffness. It is used non-invasively for staging fibrosis in chronic liver disease. Values are affected by inflammation, congestion and obesity.

Option by option

  • A. Liver stiffness as a marker of fibrosis (correct)

    Correct. Shear wave speed is a stiffness measure and correlates with fibrosis.

  • B. Bile duct diameter

    Duct diameter is measured by ultrasound or MRCP.

  • C. Hepatic blood flow velocity

    Flow velocity is assessed with Doppler.

  • D. Glycogen content

    Glycogen content is not measured.
