  1. Which special projection of the temporal bone is used to demonstrate the mastoid air cells in a tangential view?

    Answer: Law method

    The Law method (modified Law) is an axiolateral oblique projection used to demonstrate mastoid air cells in profile.

  2. For the AP axial projection of the mandible (Towne variant), the CR is directed at approximately what angle?

    Answer: 35° caudad

    For the Towne variant used to show the mandibular condyles, the CR is directed 35° caudad to the OML.

  3. A patient with suspected Jefferson fracture of C1 should be imaged with which view as the priority?

    Answer: Open-mouth AP (odontoid)

    The open-mouth AP (odontoid) view demonstrates the C1 lateral masses and C2 dens to evaluate for Jefferson or odontoid fractures.

  4. The hyoid bone is located at the level of which cervical vertebra?

    Answer: C3

    The hyoid bone is located at the level of C3 and serves as a useful landmark when positioning lateral neck radiographs.

  5. On the PA Caldwell projection of the skull, the central ray exits at which landmark?

    Answer: Nasion

    On the PA Caldwell projection, the CR exits at the nasion (bridge of the nose) after entering the posterior skull.

  6. Soft tissue lateral radiographs of the neck are used primarily to evaluate which condition?

    Answer: Epiglottitis and airway foreign bodies

    Lateral soft tissue neck radiographs are taken to evaluate the airway for epiglottitis, croup, retropharyngeal abscess, and foreign bodies.

  7. For oblique projections of the cervical spine, which structures are primarily demonstrated?

    Answer: Intervertebral foramina

    Oblique projections of the cervical spine are performed to demonstrate the intervertebral foramina on the side opposite to the rotation (RPO shows left foramina).
