Question Stem
A 45-year-old trauma patient arrives supine on a backboard. To
produce a true AP projection of the chest, which patient
orientation and instruction best ensures anatomic accuracy?
A) Rotate the torso 15° toward the left and center the CR to T7.
B) Keep the patient in the supine anatomic position with
shoulders rolled forward.
C) Ensure the patient is supine with the midsagittal plane
centered to the IR and shoulders in the same transverse plane.
,D) Turn the patient into a left lateral decubitus and elevate the
chin.
Options
A.
B.
C.
D.
Correct Answer
C
Rationales
Correct (C): A true AP projection requires the midsagittal plane
centered to the IR and symmetric shoulder positioning so
anatomy is not rotated; centering the CR appropriately
demonstrates correct anatomy. Lampignano emphasizes
aligning the midline of the body with the IR to avoid rotation.
A (incorrect): Intentional rotation does not produce a true AP
projection; it creates obliquity and alters heart and mediastinal
silhouette.
B (incorrect): Rolling shoulders forward changes shoulder girdle
position and may obscure apices; it does not assure midsagittal
centering.
D (incorrect): Turning to a lateral decubitus changes projection
type entirely; it is not an AP projection technique.
Teaching Point
Center the midsagittal plane to the IR to avoid rotation and
produce a true AP projection.

Question Stem
During a shoulder radiograph, the technologist instructs the
patient to rotate the arm laterally. Which anatomic change is
expected on the AP projection when lateral (external) rotation
of the humerus is performed?
A) The lesser tubercle is visualized in profile.
B) The greater tubercle is visualized in profile laterally.
C) The glenoid fossa is superimposed over the humeral head.
D) The acromioclavicular joint is widened medially.
Options
A.
B.
C.
D.
Correct Answer
B
, Rationales
Correct (B): External (lateral) rotation places the greater
tubercle laterally in profile, per positioning terminology
describing rotation and anatomical relationships.
A (incorrect): The lesser tubercle is profiled medially with
internal (medial) rotation, not external rotation.
C (incorrect): Glenoid-humeral relationship changes with
rotation, but the glenoid is not specifically superimposed as
described; this option is nonspecific.
D (incorrect): AC joint width is unrelated to humeral rotation
and would not be predictably widened medially.
Teaching Point
External rotation profiles the greater tubercle laterally; internal
rotation profiles the lesser tubercle medially.
