Question

What does superimposed cranial halves show when closest to the IR?

1) Sella turcica, dorsum sellae and clinoids in profile
2) Symmetric EAMs, mandibular rami, and greater wings
3) Superimposed orbital roofs, EAMs, and lesser wings
4) Cannot be determined

Answer 1

When superimposed cranial halves are closest to the Image Receptor (IR), the sella turcica, dorsum sellae, and clinoids should be visible in profile, providing orientation to the midline structures of the skull.

Step-by-step explanation:

What superimposed cranial halves show when closest to the Image Receptor (IR) can be determined by the structures that are visible in profile. When the cranial halves are superimposed closest to the IR, you should be able to see the sella turcica, dorsum sellae, and clinoids in profile. These elements of the sphenoid bone are situated in the middle cranial fossa and form the central, anchoring part of the cranial floor. The sella turcica houses the pituitary gland and is a key structure in cranial imaging, helping to orient the viewer to the midline structures of the skull.
