What is X-RAY SKULL AP?

The skull anteroposterior (AP) view is a non-angled radiograph of the skull. This view provides an overview of the entire skull rather than attempting to highlight any one region.

Indications

This examination is able to assess for medial and lateral displacements of skull fractures, in addition to neoplastic changes and Paget disease.

Note: As this view results in a higher radiation dose to the radiosensitive lens of the eyes compared to the PA view, it should only be used in situations where the patient is unable to face the detector, like in trauma settings and patients with poor mobility.

Patient position

the back of patient's head is placed against the image detector
