Sample item

Which ultrasound combination most supports gallstones?

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

The answer and the reasoning

D. Echogenic foci with posterior acoustic shadowing

Gallstones are typically echogenic and cast clean posterior acoustic shadows; they may also move with patient repositioning, unlike many gallbladder polyps or sludge deposits.

Option by option

  • A. Absent Doppler signal in every vessel

    Absent signal in every vessel would suggest a technical issue, not gallstones.

  • B. Anechoic renal cortex

    Renal cortex appearance does not diagnose gallstones.

  • C. Uniform lung aeration

    Lung aeration is poorly assessed by conventional abdominal ultrasound.

  • D. Echogenic foci with posterior acoustic shadowing (correct)

    Correct: bright mobile foci with shadowing are typical gallstone features.
