Radiographic Positioning of the Humerus and Scapula

1. Which projection is used to visualize the coracoid process in radiography?

Acromion

Inferosuperior axiolateral projection A.Coracoid process B.Glenoid Cavity C.Spine D.Acromion

Glenoid Cavity

Spine

The Inferosuperior axiolateral projection is specifically used for visualizing the coracoid process in radiography, allowing for a clear image of this anatomical structure.

Explanation

The Inferosuperior axiolateral projection is specifically used for visualizing the coracoid process in radiography, allowing for a clear image of this anatomical structure.

2. What is the correct positioning for a lateral humerus projection?

Place the CR perpendicular to the IR and centered to the elbow joint for a lateral humerus projection.

Position patient with back to IR and elbow fully extended for a lateral humerus projection.

Position patient prone for a lateral humerus projection.

The correct positioning for a lateral humerus projection involves positioning the patient erect or supine as for lateromedial or mediolateral projection, not prone. The patient should have their back to the IR with the elbow partially flexed, not fully extended. Additionally, the CR should be perpendicular to the IR and centered to the midpoint of the humerus, not the elbow joint.

3. What is the name of the projection used to visualize the scapula in an x-ray?

Lateral Scapula projection

Oblique Scapula projection

Dorsal Scapula projection

The correct answer is AP Scapula projection, which stands for Anteroposterior Scapula projection. This projection is commonly used to assess the scapula in radiographic imaging.

Explanation

The correct answer is AP Scapula projection, which stands for Anteroposterior Scapula projection. This projection is commonly used to assess the scapula in radiographic imaging.

4. In which position are the following structures typically seen on an x-ray image of the scapula: Acromion, Coracoid process, Inferior angle, Spine of scapula, Body of scapula?

Anterior Oblique Position

AP (Anterior-Posterior) Position

Lateral (Scapular Y) Position A.Acromion B.Coracoid process C.Inferior angle D.Spine of scapula E.Body of scapula

Posterior Oblique Position

The correct position for visualizing the structures mentioned is the Lateral (Scapular Y) Position, which provides a comprehensive view of the scapula from different angles.

Explanation

The correct position for visualizing the structures mentioned is the Lateral (Scapular Y) Position, which provides a comprehensive view of the scapula from different angles.

5. How should the body be positioned for an AP Humerus X-ray?

Keep the body straight and avoid any rotation for an accurate AP Humerus X-ray.

Bend the body forward to bring the elbow and distal humerus in contact with the cassette.

Rotate body away from the affected side to bring the shoulder and humerus in contact with the cassette.

For an AP Humerus X-ray, it is important to rotate the body toward the affected side to ensure proper alignment of the shoulder and proximal humerus with the cassette.
