A patient enters the emergency department (ED) because of a motor vehicle collision (MVC). The patient is on a backboard and wearing a cervical collar.  The technologist is concerned about the artifacts that the collar will project on the spine during the horizontal beam lateral projection.  What should the technologist do in this situation?

Why are the anterior positions (LAO/RAO) preferred over the posterior positions (LPO/RPO) of the cervical spine?

 Image A represents which of the following projections?

A radiograph of an AP thoracic spine projection reveals that the upper thoracic spine is overexposed. The lower vertebrae have acceptable density and contrast.  Which one of the following modifications will improve the visibility of the upper thoracic spine?   Change 

A radiograph of a RAO of the cervical spine reveals that the lower intervertebral foramina are not open. The upper vertebral foramina are well visualized.  Which positioning error most likely lead to this radiographic outcome?

With reference to the patient, where should the top border of the IR or collimated field be positioned for the AP projection of the thoracic vertebrae?

What compensation should be made in the lateral projection of the thoracic vertebral column on a recumbent patient when the lower thoracic region is not parallel with the table?

The anterior oblique thoracic spine position demonstrates the upside zygapophyseal joints.

Which evaluation criterion pertains to PA axial oblique projections of the cervical vertebral column?

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?
