Normal AP oblique shoulder radiograph

From the case: Grashey view (AP oblique shoulder radiograph)

x_ray

Oblique

Normal AP oblique internal rotation view (Grashey view). It is also known as a "true AP" view since the view is AP to the scapular instead of AP to the patient.

From the case: Grashey view (AP oblique shoulder radiograph)

Diagram

The AP oblique Grashey view is obtained with the patient rotated 35-45 degrees and his or her back (scapular body) up against the imaging detector.

How do you take a Grashey view?

This special view is known as a Grashey projection..

Have the patient in a supine or upright position. ... .

Center the cassette to the glenohumeral joint..

Rotate the body approximately 35°- 45° toward the affected side..

Abduct the arm slightly in internal rotation and place the palm of the hand on the abdomen, if possible..

How many degrees should the patients need to rotate the knees in prone position for PA oblique projection in lateral rotation?

Patella PA Oblique Lateral Rotation Position of patient Prone position. Position of part Flex knee 5-10 degrees. Externally (laterally) rotate knee 45 -55 degrees from prone position. Central ray Perpendicular to IR, exiting the palpated patella.

How much do you rotate a patient for the lateral shoulder blade projection?

Rotate the unaffected side away from the the image receptor 45-60 degrees until the flat aspect of the scapula is perpendicular to the the image receptor. The patient should suspend respiration for the exposure.

How many degrees of body rotation is recommended for oblique position of the chest?

The recommended right rotation angles are: 20 degrees for left CTR 0–23 degrees; 30 degrees for left CTR 24–44 degrees; 40 degrees for left CTR 45–66 degrees; 50 degrees for left CTR 67–87 degrees; and 60 degrees for left CTR more than 87 degrees.
