The PA oblique scapular Y projection with the upper midcoronal plane tilted towards the IR demonstrates the superior scapular angle above the clavicle (2), and a longitudinally foreshortened scapular body (3), but does not visualize the glenoid cavity on end (1) or the superior scapular angle below the clavicle (4).
