obtained? Correct Answer patient's head was tilted

without superimposition. One of each of the corresponding
structures is demonstrated posterior to the other. How was the
patient mispositioned for such a projection to be obtained?

reveals that the petrous ridges are at the level of the superior
orbital margins. Which of the following modifications are
required to correct this error? Correct Answer increase
extension
A PA cranial projection with accurate positioning demonstrates
1. equal distances from the lateral orbital margin to the lateral
cranial cortices on each side.
2. the anterior clinoids and dorsum sellae superior to the
ethmoid sinuses.
3. the petrous ridges horizontally through the lowest third of the
orbits.
4. the internal acoustic meatus horizontally through the orbital
center. Correct Answer 1. equal distances from the lateral
orbital margin to the lateral cranial cortices on each side.
2. the anterior clinoids and dorsum sellae superior to the
ethmoid sinuses.
4. the internal acoustic meatus horizontally through the orbital
center.
A PA cranial projection with poor positioning demonstrates the
petrous ridges too superior to the supraorbital margins. How was
the patient positioned for such a projection to be obtained?
1. The patient's chin was inadequately tucked.
2. The OML was not positioned perpendicular to the IR.
3. The patient's face was rotated toward the right side.
4. The patient's head was tilted. Correct Answer 2. The OML
was not positioned perpendicular to the IR.
,A PA cranium projection demonstrating the petrous ridges
superior to the supraorbital margins Correct Answer was
obtained with the patient's chin tucked more than the required
amount.
A parietoacanthial facial bone projection (Waters method)
demonstrating the petrous ridges within the maxillary sinuses
Correct Answer would have been obtained with the patient's
chin insufficiently elevated to align the MML perpendicular to
the IR.
A patient comes to radiology for a routine study of the cranium.
He is unable to flex his head and neck sufficiently to place the
OML perpendicular to the IR for the AP axial projection. What
should the technologist do to compensate for this problem
without creating excessive magnification of the occipital bone?
Correct Answer Place the IOML perpendicular to IR and
increase the CR angulation by 7 degrees
A patient comes to radiology for a sinus series on a cart
(gurney). She is unable to stand or sit erect for any of the
projections. Which of the following projections will best detect
any air/fluid levels present in the maxillary sinuses? Correct
Answer horizontal beam lateral
A patient comes to radiology for a sinus series. She cannot fully
extend her head and neck for the submentovertical projection.
What else can the technologist do to produce a diagnostic
submentovertical projection? Correct Answer Angle the CR
to place it perpendicular to IOML.
, A patient comes to radiology with a history of a possible erosion
of the superior orbital fissures. Which of the following
projections would best demonstrate this structure? Correct
Answer PA axial with a 25° to 30° caudad angle to OML
A patient comes to radiology with a possible bone cyst within
the squamous portion of the frontal bone. Which of the
following projections would best demonstrate this region with a
minimal amount of distortion of the frontal bone? Correct
Answer PA Zero
A patient enters the ED with facial bone injuries. The physician
is concerned about a possible blow-out fracture of the left orbit.
Which one of the following projections would best diagnose this
injury? Correct Answer modified waters
A patient requires a trauma AP axial cranial projection
(Caldwell method). When the central ray is aligned with the
OML, the tube angle reads 13 degrees caudad. What central ray
angle should be used? Correct Answer 2 degrees cephalad
A pediatric patient enters radiology for a paranasal sinus series.
Because of her age, the child is unable to hold still for the
projections even with the use of immobilization devices. The
decision is to hold the child during each exposure. Which of the
following individuals should be asked to hold the child?
Correct Answer guardian
A radiograph of a lateral projection of the cranium reveals that
the orbital roofs (plates) are not superimposed—one is slightly
