Sample item

Which imaging modality uses ionizing X-radiation?

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

The answer and the reasoning

A. Computed tomography

The defining Radiation physics principle supports Computed tomography; it is the answer that best accounts for the finding or clinical aim described.

Option by option

  • A. Computed tomography (correct)

    Correct. Computed tomography is the most appropriate interpretation of the key information.

  • B. Doppler examination

    Doppler examination does not provide the expected imaging or dental conclusion here.

  • C. Ultrasound

    Ultrasound may be useful in another context but is not supported by this scenario.

  • D. Magnetic resonance imaging

    Magnetic resonance imaging is less appropriate because it does not match the stated radiation physics feature.
