SET A+
✔✔1. The projection of the shoulder
demonstrated in the following image is best described as a: - ✔✔Inferosuperior axial,
Lawrence method
✔✔Which two of the following are correct positioning criteria for the inferosuperior axial
projection, Lawrence - ✔✔- Affected arm is abducted 90 degrees from the body
- Affected arm is in external rotation with the hand supinated
✔✔When performing a posteroanterior (PA) oblique projection, scapular Y of the
shoulder, the central ray should enter the vertebral border of the scapula and exit: -
✔✔The scapulohumeral joint
✔✔What is the recommended patient position for performing the posteroanterior (PA)
oblique projection, scapular Y of the shoulder? - ✔✔Standing with the affected side
closest to the image receptor (IR)
✔✔In the anteroposterior (AP) projection, neutral view of the shoulder, what is the
position of the patient's hand? - ✔✔Palm of the hand against the hip
✔✔What is the recommended central ray entrance point for an inferosuperior axial
projection of the shoulder, Lawrence method? - ✔✔axilla
✔✔What is the optimal collimation size for an inferosuperior axial projection of the
shoulder, Lawrence method? - ✔✔10x12 inches (25x 30cm)
✔✔Which of the following best describes this projection of the shoulder in the following
image? - ✔✔Anteroposterior (AP) neutral
, ✔✔For a posteroanterior (PA) oblique projection, scapular Y of the shoulder, the patient
should be rotated so they form what angle with the image receptor (IR)? - ✔✔45-60
degrees
✔✔Identify the structure that is represented by the letter (D) in the following image: -
✔✔Coracoid process
✔✔1. Where should the central ray be directed for an anteroposterior (AP) projection of
the scapula? - ✔✔2 inches (5 cm) inferior to the coracoid
✔✔Which of the following represents the correct breathing instructions for an
anteroposterior (AP) scapula projection? - ✔✔Slow respiration
✔✔Which two of the following are appropriate evaluation criteria for a lateral projection
of the scapula? (Select two) - ✔✔- Scapular body free of rib superimposition
- Humerus does not superimpose area of interest
✔✔How should the patient's affected arm be positioned when performing an
anteroposterior (AP) projection of the scapula? - ✔✔Abducted 90 degrees with the
elbow flexed and the hand supinated
✔✔Why must a patient's arm be abducted 90 degrees for a routine anteroposterior (AP)
projection of the scapula? - ✔✔Abducting the arm moves the scapula laterally for
minimal superimposition by the ribs
✔✔Mr. Garcia is a 40-year-old patient with an order for a routine scapula series due to
pain in the area for the past two weeks. He has had no prior injury and is able to move
and cooperate for the radiographic examination. How could the positioning error
demonstrated in the anteroposterior (AP) projection from the scapula series in the
following image be corrected? - ✔✔Abduct the patient's arm 90 degrees from the body
so the scapula is less
superimposed by the thoracic structures
✔✔Which of the following best identifies the projection demonstrated in the following
radiograph? - ✔✔Lateral scapula
✔✔Which two of the following are acceptable patient positions when performing an
anteroposterior (AP) scapula radiograph?
(Select two) - ✔✔- Standing at the upright bucky
- Lying supine on the radiographic table
