| (True/False) Lesions of decreased density are termed osteoblastic lesions | False |
| Situation: A patient comes to radiology for a study of the sella turcica. Which of the following routines would best demonstrate this strucutre | AP axial & lateral projections |
| How many bones make up the facial bone region | 14 |
| Which of the following cranial bones does not articulate with the parietal bones? (Frontal, Sphenoid, Occipital, or All of the above) | All of the above |
| The frontal bone articulates with ____ cranial bones. | Four |
| Which of the following landmarks corresponds with the level of the petrous ridge | Top of ear attachment (TEA) |
| Which cranial bone contains the cribriform plate | Ethmoid |
| Which of the following sutures separates the parietal from the occipital bone | Lambdoidal |
| The ethmoid notch is part of which cranial bone | Frontal |
| Situation: Dorsum sellae is projected below the foramen magnum, but the anterior arch of C1 is visible with the foramen. | Excessive CR angulation |
| Situation: Orbital plates are not superimposed, one is slightly superior to the other | Tilt |
| Situation: Study of the cranium, patient is unable to flex his head and neck sufficiently to place the OML perpendicular to the IR for the AP axial. | Use the IOML and increase the CR angulation to 7 degrees |
| what is the largest immovable bone of the face | Maxilla |
| Which facial bone forms the majority of the hard palate | Maxilla |
| Which three cranial bones articulate directly with the zygomatic bone | Frontal, spheniod, temporal |
| Which of the following structures are described as scroll-like projections found in the nasal cavity | Conchae |
| Which two bones form the bony nasal septum | Ethmoid and vomer |
| The upper and lower teeth are embedded in the | alveolar processes |
| The posterior aspect of the orbit is termed the | Apex |

| what is the only paranasal sinus not contained within a cranial bone | Maxillary |
| The term antrum of highmore is an older term for the | maxillary sinuses |
| Which of the fontanels is the last to close at about 18 mounts of age | Anterior |
| Situation: AP axial projection reveals that the dorsum sellae is projected below the foramen magnum, the anterior arch of C1 is visible within the foramen. Which of the following posit. error let to this | Excessive CR angulation |
| Which of the following projections for the sella turcia best visualized the anterior clinoid processes | AP axial, CR 30 degree caudal to IOML |
| Situation: Caldwell method reveals that the petrous ridge are located at the level of the lower one third of the orbits. The tech performed this projection with the CR angles 15 degrees caudal to the OML. How must positioning be altered | Positioning was correct |
| Situation: A radiograph of a lateral projection of the cranium reveals that the orbital plates are not superimposed, one is slightly superior to the other. Which of the following positioning errors led to this outcome | Tilt |
| Situation:A lateral cranium reveals that the mentum was cut off from the bottom of the image. A 10x12" IR was used and it was place crosswise. What must be altered if a repeat exposure is performed? | None of the above; centering and IR placement were correct |
| Situation: Patient is unable to flex his head and neck sufficiently to place OML perpendicular to the IR for the AP axial projection. What should the tech. do to compensate for his problem without creating excessive mag. of the occipital bone | Use the IOML and increase the CR angulation 7 degrees |
| Situation: A patient enters the ER with possible basilar skull fracture. Which of the following skull projections would best demo any blood present in the sphenoid sinus | Horizontal beam lateral projection |
| Situation: A patient comes to radiology with possible bone cyst within the squamous portion of the frontal bone. Which of the following projections would best demo this region with a minimal amount of distortion of the frontal bone | PA with no CR angulation to OML |
| Which of the following skull projections results in the highest thyroid dose | Submentovertex |
| Which division of the temporal bone contains the organs of hearing and equilibrium | Petrous |

| To which aspect of the ear does the Eustachian tube attach | Middle ear |
| Which of the following structures of the inner ear is responsible for hearing | Cochlea |
| Where is the CR centered for a lateral projection of the cranium | Two inches superior to EAM |
| Where is the CR centered for a lateral projection of the sella turcica | three-fourths inch (2cm) anterior 3/4 inch (2cm) superior to EAM |
