exposure made during slow breathing to eliminate lung detail and clearly show scapula

39
Q

what is the most lateral joint in the shoulder girdle?

A

AC joint

40
Q

arm position for lateral scapula

A

flex elbow, place back of hand on posterior thorax, ensure humerus does not overlap scapula

41
Q

which borders of the scapula are perpendicular to the IR in a lateral view?

A

lateral and medial borders

42
Q

How is the affected upper limb positioned to demonstrate the acromion and coracoid on the lateral projection of the scapula?

Elbow flexed with the back of the hand resting on the posterior thorax

43
Q

how should the arm be positioned to demonstrate the body of the scapula?

A

arm extended upward and rest forearm on head

44
Q

CR placement for lateral scapula

A

perpendicular to midmedial border of scapula

45
Q

collimation of lateral scapula

A

12 in length, 1.5 in above shoulder, 1 in beyond lateral shadow
