| What is the only paranasal sinus not contained within a cranial bone? | Maxillary |
| Which bone is involved with a tripod fracture? | Zygomatic |
| A fracture involving the facial bones where a blow to one side causes a fracture to the opposite side is termed a ____ fracture. | Contrecoup |
| Where is the CR centered for a lateral projection of the facial bones? | Zygoma, midway between the EAM and the outer canthus |
| How much skull tilt and rotation are required for the oblique inferosuperior (tangential) projection for zygomatic arches? | 15 degrees |
| Why is the chin extended for an axiolateral/axiolateral oblique projection of the mandible? | To prevent superimposition upon the cervical spine |
| Where is the CR centered for a lateral projection of the sinuses? | Midway between the outer canthus and the EAM |
| Which facial bones are NOT visible from the skeleton's exterior? | Vomer and Palatine bones |
| The interpupillary line (IPL) helps determine...? | Head tilt |
| This condition results in fragile and deformed bones over time. | Paget Disease |
| This fracture type is also referred to being a "ping-pong" fracture. | Depressed |
| A modified Waters view has the patient place their...against the bucky. | Nose and chin |
| A tripod fracture affects the arch, the maxillary process and the...? | orbital process |
| The following study requires axiolateral obliques to be done with open and closed-mouth images. | TMJ |
| True or False: When imaging nasal bones, it is important you include all soft tissues of the nose. | True |
| A short and more broad-shaped head is referred to as being...? | Bradycephalic |
| Which of the following is NOT a sinus cavity? Sphenoid, Nasal, Maxillary, Ethmoid? | Nasal |

| The area where cranial bones are fused together are called...? | Sutures |
| The intervertebral foramina of the lumbar spine are located at an angle of .....in relation to the midsagittal plane. | 90 degrees |
| The superior and anterior projecting bony process of the sacrum that forms part of the inlet and articulates with L5 is the: | promontory of the sacrum |
| Which specific aspect of the sacrum articulates with the ilium to form the sacroiliac joint? | auricular surface |
| What is the term for the superior aspect of the coccyx? | base |
| What is the joint classification of the zygapophyseal joints? | synovial/diarthrodial |
| The intervertebral joints in the lumbar spine are classified as: | cartilaginous/amphiarthrodial |
| What type of CR angulation is required for an AP axial projection of the coccyx? | 10-degree caudal |
| The radiographic appearance on an oblique lumbar spine in which the neck of the Scottie dog appears “broken” suggests the presence of: | Spondylolysis |
| A destructive type of lesion with irregular margins and increased brightness is an indication of possible: | osteolytic type of metastases |
| A fracture through the vertebral body and posterior elements caused by lap seat belts during an auto accident involving sudden deceleration is a .... fracture. | Chance |
| An anterior wedging of vertebrae with a loss of body height but rarely causing neurologic symptoms is called: | compression fracture |
| Sciatic type of pain resulting from a “slipped disk” indicates: | herniated nucleus pulposus |
| An abnormal lateral curvature of the spine is a congenital condition termed: | Scoliosis |
| What CR angle should be used for a lateral sacrum/coccyx projection? | None, the CR should be perpendicular to the IR |
| Which of the following fractures is due to a hyperflexion force injury? | Chance |
| How much obliquity of the body is required for posterior oblique (LPO/RPO) positions for the sacroiliac joints? | 25-30 degrees |
| A radiograph of the left sacroiliac joint demonstrates it open and clearly seen. How was the patient positioned to obtain this view? | RPO |
| The “nose” of the Scottie dog represents the spinous process of a lumbar vertebra. | False |
| True or False: The LPO position for sacroiliac joints will best demonstrate the right joint. | True |
| The nose of the Scottie Dog correlates to what anatomical structure? | Transverse Process |
| True or False: It is OK to have the patient flex their hips and knees 90 degrees for an AP axial view of the sacrum. | False |
| A Scottie Dog is created when the body is rotated .....degrees. | 45 |
| True or False: For L-spine, the intervertebral foramina are formed at a 45 degree oblique, while the zygapophyseal joints are formed at a 90 degree oblique (lateral) | False, it's reversed. Intervertebral foramina are formed at 90 degrees, while z-joints are formed at ~45 degrees. (C-Spine is: Z's at 90, IV Foramina at 45) |
