Where is the shoulder marked to localize the central ray?
Over the superior margin of the humeral head
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.
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.
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
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
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.
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
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
Which of the following is increased in mobile radiography?
- Grid ratio
- Occupational exposure
- Anode heel effect
1 and 2 only
1 and 3 only
2 and 3 only
1, 2, and 3
Which of the following is increased in mobile radiography?
- Grid ratio
- Occupational exposure
- Anode heel effect
2 and 3 – Occupational exposure and the anode heel effect are both increased in mobile radiography.
How would a very ill patient be positioned for a mobile chest examination to demonstrate fluid in the left lung?
Supine
Fowler’s position
Left lateral decubitus
Right lateral decubitus
How would a very ill patient be positioned for a mobile chest examination to demonstrate fluid in the left lung?
Left lateral decubitus
