Exam 5: Humerus and Shoulder Girdle

An AP apical oblique projection for an anteriorly dislocated scapulohumeral joint will project the humerus _____ to the glenoid cavity.

Which one of the following projections/positions should NOT be performed for a possible shoulder dislocation?

A referring physician suspects that a subacromial spur may be the cause for a patient's arm numbness.She asks the technologist for a projection that would best demonstrate any possible spurs.Which of the following projections would accomplish this objective?

Which of the following best demonstrates the coracoacromial arch?

For AC joint weight-bearing studies,patients should not be asked to hold on to the weights with their hands; rather,the weights should be attached to the wrists.

Which of the following modalities best demonstrates shoulder joint pathology such as rotator cuff tears using dynamic evaluation techniques during joint movements?

A patient is scheduled for an arthrogram.During the course of the study,the radiologist requests a projection to demonstrate the intertubercular groove.Which one of the following projections would best demonstrate this structure?

Which of the following AP shoulder projections demonstrates the greater tubercle in profile medially?

Which ionization chamber(s)for the AEC should be used for a tangential projection for an intertubercular groove?

What is a possible radiographic sign for impingement syndrome of the shoulder?

How much posterior CR angulation is required for the supine version of the tangential projection for the intertubercular (bicipital)groove?

Which projection of the shoulder requires that the patient be rotated 45° to 60° toward the IR from a PA position?

MATCHING Select the correct method name to match each shoulder projection.(Use each choice only once.) -Inferosuperior axial projection

A patient comes to radiology for treatment of an arthritic condition of the right shoulder.The radiologist orders AP internal/external rotation projections and an inferosuperior axiolateral projection of the scapulohumeral joint.However,the patient cannot abduct the arm for this projection.Which other projection will best demonstrate the scapulohumeral joint space?

Which of the following shoulder projections best demonstrates the glenoid cavity in profile?

A radiograph of a transthoracic lateral projection reveals that it is difficult to visualize the proximal humerus due to the ribs and lung markings.The following analog exposure factors were used: 75 kV,30 mAs,40-inch (102 cm)SID,grid,and suspended respiration.Which of the following changes will improve the visibility of the proximal humerus?

Where is the CR centered for the posterior oblique position for the glenoid cavity?

Which term describes the medial end of the clavicle?

A radiograph for an AP projection with external rotation of the proximal humerus reveals that the greater tubercle is profiled laterally.What should be changed to improve this image for a repeat exposure?

Where is the CR centered for the bilateral acromioclavicular (AC)joint projection on a single 14- *17-inch (35 *43 cm)image receptor?
