3

Where is the shoulder marked to localize the central ray?

1 inch (2.5 cm) inferior and medial to the coracoid process

At the AC joint

Over the superior margin of the humeral head

2 inches (5 cm) medial from the superolateral border of the shoulder

Where is the shoulder marked to localize the central ray?

Over the superior margin of the humeral head

4

It is acceptable in trauma radiography to lower image evaluation criteria, because patients generally cannot cooperate with standard positioning protocols.

True

False

It is acceptable in trauma radiography to lower image evaluation criteria, because patients generally cannot cooperate with standard positioning protocols.

False – Image quality is essential to an accurate diagnosis, so image evaluation standards are the same in trauma as in other standard procedures.

5

Immobilization devices can be removed only by physician’s order, even if the devices will cause artifacts in images.

True

False

Immobilization devices can be removed only by physician’s order, even if the devices will cause artifacts in images.

True – The immobilization is left in place during trauma radiographic procedures.

6

The lateral projection of the cervicothoracic vertebrae is required:

For all trauma C-spine procedures

When C7 (and the C7-T1 interspace) is not demonstrated on the lateral C-spine image

Only for suspected lower cervical trauma

Only for suspected upper thoracic trauma

The lateral projection of the cervicothoracic vertebrae is required:

When C7 is not demonstrated on the lateral C-spine image

7

Which of the following will demonstrate air-fluid levels on trauma chest image?

Supine AP

Recumbent left lateral

Dorsal decubitus

All of the above

Which of the following will demonstrate air-fluid levels on trauma chest image?

Dorsal decubitus

8

In trauma imaging of long bones, it is acceptable to include only the joint closer to the injury.

True

False

In trauma imaging of long bones, it is acceptable to include only the joint closer to the injury.

False – Both joints must be included in two projections, 90 degrees from each other, in trauma images of long bones.

9

Parallel, beside the bed

Perpendicular to the side of the bed

Where would the mobile radiographic unit be placed to perform an AP projection of the chest on a patient who is able to sit upright?

At the end of the bed

10

Which of the following is increased in mobile radiography?


1. Grid ratio

2. Occupational exposure

3. Anode heel effect


2 and 3 – Occupational exposure and the anode heel effect are both increased in mobile radiography.
