the patient is seated and the elbow is fully flexed (unless contraindicated)

26
Q

For the distal humerus olecranon process, where does the CR enter and at what angle?

A

the CR is perpendicular and enter about 2” superior to the olecranon process

27
Q

What is seen on the olecranon process image?

A

the olecranon process and distal humerus

28
Q

What is the olecranon process image sometimes ordered as?

A

a Jones

29
Q

What is another name for the shoulder/proximal humerus transthoracic lateral?

A

Lawrence method

30
Q

What is the transthoracic lateral shoulder/proximal humerus (Lawrence method) somewhat similar to

A

the swimmer’s technique for a lateral C-T spine

31
Q

When would you do a transthoracic lateral shoulder/proximal humerus (Lawrence method)?

A

when there is trauma to the area and the arm may be immobilized

32
Q

What is the position of the patient for the shoulder/proximal humerus transthoracic lateral (Lawrence method)?

A

standing, seated, or recumbent

33
Q

What is the size of the IR for the transthoracic (Lawrence method) and where is the CR centered?

A

10x12 LW and the CR is centered to the surgical neck of the affeccted arm

34
Q

What are the breathing instructions for the Lawrence method?

A

exposure is made when breathing is suspended after full inhalation or a breathing technique may be used if equipment permits (3-5 sec exposure time)

35
Q

What is seen in the Lawrence method for the transthoracic shoulder/proximal humerus?

A

the proximal humerus, scapula, and clavicle

36
Q

What position is the pt in for the inferosuperior axial shoulder position?

A

supine

37
Q

What is the angle of the CR for the inferosuperior axial shoulder?

A

15-30 degrees toward the body

38
Q

What is the west point method?

A

the inferosuperior axial shoulder when the pt is prone

Q

What is the position of the affected arm during the west point method?

A

dangling over the table

40
Q

For the superioinferior axial shoulder how is the patient postioned?

A

either seated or recumbent with arm (humerus) abducted

41
Q

For the superoinferior axial shoulder how is the IR and CR centered?

A

tot he shoulder joint with the CR angles 5-15 degrees laterally (depending on how well the pt extends sholder over IR.)

42
Q

Thoracolumbar Spine is done for what dx?

A

Scoliosis

43
Q

Why is PA recommended for the Thoracolumbar spine?

A

for less radiation exposure to radiosensitive organs. A lateral may also be included

44
Q

What image is stitching used?

A

the thoracolumbar spine for scoliosis

45
Q

In the thoracolumbar spine, the iliac crests are usually included for…

A

spine angle measurements

46
Q

Spine-R/L bending is sometimes confused with on order for what?

A

lateral bending and the spine-lateral hyperflexion/hyperextension images

47
Q

What image can be done AP or PA as well as weight bearing or non weight bearing? (spine)

A

Spine-R/L bending

48
Q

the soft tissue neck can be done….

A

lateral only or AP and lateral

49
Q

what is the angle of the CR and entrance point for the soft tissue neck?

A

the CR is perpendicular and enters at the level of the manubrium

50
Q

What are the breathing instructions for the soft tissue neck?

A

inhale slowly during the exposure.

51
Q
