Grashey view (AP oblique shoulder radiograph)
The Grashey view (an AP oblique glenohumeral radiograph with internal rotation) is designed to prevent overlap of the humeral head and the glenoid. It is also known as a "true AP" view of the shoulder.
- the patient's back is toward the image detector, with the patient's body angled 35-45 degrees, and his or her scapula up against the detector
- the humerus is internally rotated
X-ray beam features
- the beam travels anterior to posterior (AP) direction, directed parallel to the glenohumeral joint
- source-to-image distance: 40" (100 cm)
- 70-75 kVp at 10 mAs (or AEC)
