A radiograph of an open-radiographic mouth projection reveals that the base of the skull is superimposed over the dens. What positioning error lead to this outcome?

How many degrees and in which direction should the CR be directed for an AP axial projection of the coccyx?

Image E is an AP projection. Which position is it?

A radiograph of an AP axial sacrum reveals that it is foreshortened, and the sacral foramina are not clearly seen. The patient was in an AP supine position, and the technologist angled the CR 10° cephalad.  What specific positioning error is present on this radiograph?

Refer to Image H, where is the CR directed?

A radiograph of a lateral thoracic spine reveals that there is excessive density along the posterior aspect of the spine. Even with good collimation, the scatter radiation reaching the IR obscures the spinous processes.  What can the technologist do to improve the visibility of the posterior structures of the spine?

A patient comes to radiology for a follow-up study of the cervical spine. The patient had spinal fusion between C5 and C6 performed 6 months earlier.  His physician wants to assess the cervical spine for anteroposterior mobility.  Which of the following projections would provide this assessment?

Which evaluation criteria pertains to the lateral projection of the cervical vertebral column?

The most posterior aspect of a typical vertebra is the:
