Answer to Question 1

greater wings of the sphenoid

Rationale: Rotation is evidenced on a radiograph when the anatomy is shifted anterior to posterior to one another. The mandibular rami or greater wings of the sphenoid will indicate rotation.

Answer to Question 2

decrease time

Rationale: A reduction in time should be applied in instances where patient motion is of concern. If a faster time is needed to avoid motion, mA may be increased accordingly.
