Sample item

What CT appearance is expected for air?

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

The answer and the reasoning

C. Very low attenuation

The central CT principle supports Very low attenuation; it is the answer that most directly explains the image finding, modality choice, or oral-health feature described.

Option by option

  • A. Very high attenuation

    Very high attenuation does not fit the stated ct context.

  • B. Same as cortical bone

    Same as cortical bone may be used elsewhere but is not the strongest answer here.

  • C. Very low attenuation (correct)

    Correct. Very low attenuation best matches the key information in this scenario.

  • D. Same as iodinated contrast

    Same as iodinated contrast is not supported by the imaging or dental clue provided.
