  1. Which projection of the paranasal sinuses requires the patient to be erect with a horizontal beam to demonstrate air-fluid levels?

    Answer: All paranasal sinus projections

    All projections of the paranasal sinuses must be performed erect with a horizontal beam so that air-fluid levels can be demonstrated within the sinuses.

  2. The Stenvers projection (posterior profile) of the temporal bone demonstrates which structure in profile?

    Answer: Petrous pyramid

    The Stenvers projection places the petrous pyramid in profile, demonstrating the internal auditory canal and semicircular canals.

  3. On a lateral projection of the skull, the EAMs (external auditory meatuses) should be superimposed — what does separation of the EAMs indicate?

    Answer: Rotation

    Separation of the EAMs on a lateral skull indicates rotation of the patient's head from the true lateral position.

  4. Which projection of the facial bones best demonstrates the orbital floors and blow-out fractures?

    Answer: Parietoacanthial (Waters)

    The Waters projection best demonstrates the orbital floors, maxillary sinuses, and is used to detect blow-out fractures of the orbital floor.

  5. A patient cannot extend their neck for a standard AP open-mouth odontoid view. Which alternative projection demonstrates the dens?

    Answer: Fuchs method (AP axial)

    The Fuchs method is an AP axial projection with the CR directed toward the mentum, projecting the dens through the foramen magnum when the mouth cannot be opened.

  6. For the AP projection of the skull (Grashey method), where does the central ray enter?

    Answer: Nasion

    In the AP skull (Grashey method), the CR enters at the nasion and exits perpendicular to the OML at the center of the image receptor.

  7. When performing a lateral projection of the nasal bones, what is the recommended kVp range?

    Answer: 50–60 kVp

    Nasal bone radiographs require low kVp (50–60 kVp) to provide adequate contrast for the thin, delicate nasal bones against surrounding soft tissue.
