A

Right zygapophyseal joints

18
Q

The articular surfaces of the articular processes of the vertebrae are called

A

Facets

19
Q

What is the CR angle and direction for the AP Axial projection of the sacrum

A

15 degrees cephalad

20
Q

Which SI joint is demonstrated when the patient is positioned in a 25-30 degree RPO position

A

The left sacroiliac joint is demonstrated

21
Q

An abnormal lateral curvature of the spine is called

A

Scoliosis

22
Q

On which projection of the spine is the Scottie dog configuration demonstrated

A

Oblique projection of the lumbar spine

23
Q

When using a 35x43cm IR, where should the CR enter the patient for an AP projection of the lumbar spine?

A

At the level of the iliac crest in the midline of the patient

24
Q

Where does the CR enter the patient for an AP projection of the lumbar spine?

A

At the level of the iliac crest, centered to the MSP

25
Q

What is the rationale for using a 72in SID for the lateral projection of the cervical spine?

A

This SID helps to overcome the magnification caused by the increased OID of the position

Q

What specific spine anatomy is demonstrated on a lateral projection of the lumbar spine?

A

Intervertebral foramina

30
Q

What is the odontoid process and where is it located?

A

A toothlike projection on the superior surface of C2
