An AP axial coccygeal projection demonstrates the symphysis pubis superimposed over the second and third coccygeal vertebrae. How was the positioning setup mispositioned for such a projection to be obtained?

Question

Quizplus · Accepted Answer

A correctly positioned AP axial coccygeal projection should show the coccyx without superimposition of any other structures. If the symphysis pubis is superimposed with the coccyx, it means that the central ray was angled too cephalically, causing the pelvic region to be projected forward and the symphysis pubis to be superimposed over the coccyx. Rotation, leg extension, or caudal angulation would not result in this specific superimposition.
