and Answers 2025
A fracture involving the facial bones where a blow to one side causes a fracture to the
opposite side is termed a ____ fracture. - ANSWER-contrecoup
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? - ANSWER-Use IOML increase
angulation by 7 degrees
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? -
ANSWER-PA Axial with 25-30 degree caudal 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? - ANSWER-PA with no CR
angulation to OML
A patient enters the emergency department (ED) with a possible basilar skull fracture.

positioning errors led to this radiographic outcome? - ANSWER-tilt
A radiograph of a PA Caldwell projection reveals that the petrous ridges are projected
into the lower one third of the maxillary sinuses. Which of the following modifications
should be made during the repeat exposure to produce a more diagnostic image? -
