Sample item

What is the principal advantage of CT angiography in suspected pulmonary embolism?

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

The answer and the reasoning

C. Direct visualization of intraluminal pulmonary arterial filling defects

CT pulmonary angiography visualizes contrast filling defects within pulmonary arteries and is interpreted with pretest probability and contraindications in mind.

Option by option

  • A. Measurement of pulmonary function without radiation

    It is an anatomical imaging study, not pulmonary function testing.

  • B. Replacement of clinical probability assessment

    Clinical probability still guides appropriate testing.

  • C. Direct visualization of intraluminal pulmonary arterial filling defects (correct)

    Correct: emboli appear as defects within opacified pulmonary arteries.

  • D. Detection of every microscopic embolus

    No test detects every microscopic embolus.
