Pathology Matching: Fracture through pedicles and anterior arch of C2 with forward displacement upon C3 Abnormal or exaggerated convex curvature of the Thoracic spine Avulsion fracture of spinous process of C7 A form of rheumatoid arthritis Impact fracture from axial loading of anterior and posterior arch of C1 Mild form of scoliosis and kyphosis developing during adolescence Congenital defect in which the posterior elements of the vertebrae fail to unite Most common at the level of L4-5 and may result in sciatica Forward displacement of one vertebra onto another A vertebra that takes on a characteristic of the adjacent region of the spine, e.g. cervical or lumbar ribs

The AP-axial-vertebral arch projection may be performed to better demonstrate the:

Which of the following does not apply to a lateral projection of the cervical spine?

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?

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

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?
