Sample item

What is the radiographic appearance of cortical bone?

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

The answer and the reasoning

A. Radiopaque white

Cortical bone attenuates X-rays strongly because of its mineral content and consequently appears relatively white or radiopaque on a radiograph.

Option by option

  • A. Radiopaque white (correct)

    Correct: mineralized cortical bone appears radiopaque.

  • B. Invisible

    Bone is readily visible on conventional radiography.

  • C. Radiolucent black

    Radiolucent black is the appearance of air.

  • D. Gas density

    Gas density describes air, not cortex.
