Sample item

What projection is preferred for a standard ambulatory chest radiograph?

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

The answer and the reasoning

C. Posteroanterior

A posteroanterior chest radiograph minimizes cardiac magnification and gives a more reproducible assessment of lungs, pleura, and mediastinum in ambulatory patients.

Option by option

  • A. Lateral decubitus only

    Lateral decubitus is a special view for mobile pleural fluid or air.

  • B. Oblique skull view

    Oblique skull view does not image the chest.

  • C. Posteroanterior (correct)

    Correct: PA projection reduces cardiac magnification.

  • D. Anteroposterior supine

    AP supine images are often portable and magnify the heart more.
