Which of the following are disadvantages of an AP projection of the cranium as compared with a PA projection?
1) Cannot be used on injured patients
2) Increased magnification of anterior anatomy
3) Increased radiation dose to eyes

Question

Quizplus · Accepted Answer

The AP (anteroposterior) projection of the cranium results in increased magnification of the anterior anatomy due to the increased object-to-image receptor distance for these structures. Additionally, the AP projection directs more radiation through the orbits, increasing the dose to the eyes compared to the PA (posteroanterior) projection. It is not correct that AP projections cannot be used on injured patients; in fact, they are often used when the patient's condition does not allow for PA projections.
