Question 1

Which of the following projections will best demonstrate a compression fracture of the thoracic spine?

Accepted Answer

A lateral projection will best demonstrate a compression fracture of the thoracic spine as it provides a clear view of the vertebral bodies, allowing for identification of any deformities or fractures. The other options may be useful in diagnosing other spinal conditions, but are not as specific for identifying compression fractures of the thoracic spine.

Question 2

A critique of the image demonstrates which repeatable error?

Accepted Answer

The answer of A critique of the image demonstrates which...

Question 3

MATCHING
Match the vertebra with the corresponding terms and/or structures.(You may use an answer more than once.)
-Vertebra prominens

Accepted Answer

Vertebra prominens is also known as C7.

Question 4

The superior articular facet is labeled _____.

Accepted Answer

The answer of The superior articular facet is labeled _____.
...

Question 5

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

Accepted Answer

Hyperflexion and hyperextension projections allow for assessment of anteroposterior mobility by capturing the range of motion of the cervical spine. This would be the best choice for assessing the patient's spinal fusion and cervical spine mobility.

Question 6

The structure transverse foramen is labeled _____.

Accepted Answer

The answer of The structure transverse foramen is labeled _____.
...

Question 7

This radiographic image represents which of the following projections and/or positions?

Accepted Answer

The answer of This radiographic image represents which of the...

Question 8

Which imaging modality will best demonstrate herniated nucleus pulposus in the cervical spine?

Accepted Answer

Magnetic resonance imaging (MRI) will best demonstrate the herniated nucleus pulposus in the cervical spine because it provides high resolution images of soft tissues, including the discs and nerves. CT and nuclear medicine do not provide as clear images of soft tissues, and hyperflexion and hyperextension lateral projections may only show abnormal motion and not necessarily the herniation itself.

Question 9

A patient comes to radiology for a follow-up study for a clay shoveler's fracture.Which of the following projections will best demonstrate the extent of this fracture?

Accepted Answer

A lateral cervical spine projection is best for visualizing a clay shoveler's fracture, which typically occurs at the spinous process of the lower cervical vertebrae.

Question 10

The structure transverse process is labeled _____.

Accepted Answer

The answer of The structure transverse process is labeled _____.
...

Question 11

MATCHING
Match the vertebra with the corresponding terms and/or structures.(You may use an answer more than once.)
-Dens

Accepted Answer

The dens is a structure found on the second cervical vertebra, also known as C2.

Question 12

Accepted Answer

The answer of The structure lamina is labeled _____.
 ...

Question 13

The structure pedicle is labeled _____.

Accepted Answer

The answer of The structure pedicle is labeled _____.
 ...

Question 14

The structure anterior arch of the atlas is labeled _____.

Accepted Answer

The answer of The structure anterior arch of the atlas...

Question 15

A digital (CR)image taken of a lateral thoracic spine projection demonstrates poor visibility of the spine.The image was taken on a full 14 *17-inch (35 *43 cm)IR.The following factors were used during the exposure: 80 kV,80 mAs,40-inch (102 cm)SID,and collimation to the size of the IR.Which one of the following modifications will result in a more diagnostic image?

Accepted Answer

Collimating to the spine will reduce scatter radiation and improve image contrast, enhancing the visibility of the spine.

Question 16

A patient enters the ED due to an MVA.He is on a backboard and in a cervical collar.The initial lateral cervical spine projection demonstrates C1 to C6.The patient has broad and thick shoulders.Because the hospital is in a rural setting,no CT scanner is available.Which of the following modifications would best demonstrate the lower cervical spine?

Accepted Answer

The horizontal beam cervicothoracic (swimmer's) lateral position will allow the shoulders to spread out and not superimpose over the cervical spine, resulting in a clear visualization of the lower cervical spine. This is the best choice as it does not require any additional exposure to radiation or compromising the patient's position.

Question 17

Stress from a severe whiplash type of injury may cause a fracture of the structure labeled _____.

Accepted Answer

The answer of Stress from a severe whiplash type of...
