Which special projection of the shoulder places the glenoid cavity in profile for an "open" scapulohumeral joint?

• Garth method

• Transthoracic lateral (Lawerence method)

• Fisk modification

• Grashey method

What type of CR angle is required for the apical AP axial shoulder (Garth method) projection?

• 15 degrees cephalad

• 10 - 15 degrees caudad

• 30 degrees caudad

• 45 degrees caudad

For the erect version of the tangential projection for the intertubercular sulcus, the patient leans forward _____ from verticle.

• 5 - 7 degrees

• 20 - 25 degrees

• 10 - 15 degrees

• 35 - 45 degrees

What is the major advantage of the supine, tangential version of the intertubercular sulcus projection over the erect version?

• Less radiation exposure

• Reduced object-image receptor distance

• Less risk for motion

• Ability to use automatic exposure control

Which of the following projections best demonstrates the supraspinatus outlet region?

• Tangential projection (Neer method)

• Fisk method

• Inferosuperior axial projection

• PA axial transaxillary projection (Bernageau method)

With which of the following projections can an orthostatic (breathing) technique be used?

• Grashey method

• Transthoracic lateral for humerus

• Scapular Y lateral

• Garth method

What central ray angulation is required for the tangential projection-supraspinatus outlet (Neer method)?

• 10 - 15 degrees caudad

• 45 degrees caudad

• 25 degrees anteriorly and medially

• None; central ray is perpendicular

Which clinical indication is best demonstrated with the Garth method?

• Bursitis

• Rheumatoid arthritis

• Scapulohumeral dislocations

• Signs of shoulder impingement

Which anatomy of the shoulder is best demonstrated with a PA axial (Bernageau method)?

• Scapulohumeral joint space

• Coracoacromial arch

• Corcaoid process

• Intertubercular (bicipital) sulcus

If the patient cannot fully abduct the affected arm 90 degrees for the inferosuperior axial transaxillary projection (Clements modification), the technologist can angle the CR _____ degrees toward the axilla.

• 5 - 15 degrees

• 20 - 25 degrees

• 25 - 30 degrees

• 45 degrees
