The AP oblique shoulder projection (Grashey method) involves positioning the patient's midcoronal plane at a 45-degree angle with the image receptor (IR) to properly visualize the glenohumeral joint without overlap from the ribs and scapula. The central ray is centered to the coracoid process to ensure the joint space is well depicted. The patient is rotated toward the affected shoulder to achieve the oblique position, and the image can be obtained with the patient in an upright position, which is beneficial for patients who cannot lie down comfortably or to utilize gravity in positioning.
