Sample item

Which ultrasound Doppler use is most appropriate in suspected testicular torsion?

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

The answer and the reasoning

A. Compare intratesticular arterial flow with the opposite side

Colour and spectral Doppler can demonstrate reduced or absent intratesticular perfusion compared with the contralateral testis in suspected torsion.

Option by option

  • A. Compare intratesticular arterial flow with the opposite side (correct)

    Correct: perfusion asymmetry supports the urgent torsion diagnosis.

  • B. Measure bone mineral density

    Bone density requires dedicated absorptiometry.

  • C. Assess lung interstitial oedema

    Lung oedema is not a testicular Doppler indication.

  • D. Confirm a skull fracture

    Skull fractures are assessed with radiography or CT.
