True
100
true or false. do you angle 5-15 degrees through the shoulder joint, and towards the elbow?
TRUE
100
What is the breathing technique for a PA oblique projection?
Suspended respiration
100
What is the most common x-ray procedure?
chest x-ray
200
what is projected above the shoulder that is closest to the IR?
Answer: unaffected clavicle and humerus.
200
what is letter C?
scapulohumeral joint
200
Do you shield gonads for this projection?

The patient must be rotated only to 45°
False
45-60°

What is 1 evaluation criteria of the Transthoracic Lateral Projection?
- Scapula, clavicle, and proximal humerus seen through the lung field.
- Scapula superimposed over the thoracic spine.
Unaffected clavicle and humerus projected above the shoulder closest to the IR.
300
which area of the body should the central ray enter and is there tube angulation?
horizontally through the axilla to the region of the AC articulation.
CR depends on degree of medial angulation, often 15-20°
300
is the lesser tubercle in profile or the greater tubercle for this projection?
lesser tubercle is in profile
300
What is the orientation and central ray centering for a PA oblique projection?
perpendicular to the scapulohumeral joint
300
What is the average kVp and mAs for a shoulder?
70 kVp 20 mAs
400
What is the breathing instructions?
Answer: Full inspiration (Having lungs full of air improves the contrast and decreases the exposure necessary to penetrate the body).
400
True or False
When using a horizontally directed central ray, the patient should be placed in the supine body position
True
400
what is the breathing technique for this projection?
suspended respiration

500
true or false. Is the patient seated for this projection?
yes, the patient is seated at the end of the table.
500
In anterior dislocations, what is found?
the humeral head is beneath the coracoid process (subcoracoid)
- posterior (subacromial) dislocations, the humeral head is projected beneath the acromion
