Final Study Material RTE 1523C - Study Answer Collection The intervertebral foramina of the thoracic spine are clearly demonstrated on which projection? - answer - lateral The spinal cord tapers off to a point distally at the vertebral level of: - answer - L1-2 On average, how many separate bones make up the adult vertebral column? - answer - 26 Scoliosis is defined as an abnormal or exaggerated _____ curvature. - answer - lateral The joints between articular processes of vertebra are termed _____ joints. - answer - zygapophyseal Kyphosis is defined as a(n): - answer - abnormal thoracic curvature with increased convexity The zygapophyseal joints of the cervical spine are clearly demonstrated on which projection? - answer - lateral Which aspect of the intervertebral disk is composed of semigelatinous material? - answer - Nucleus pulposus Which of the following positions will demonstrate the left intervertebral foramina of the cervical spine? - answer - LAO What type of CR angle is required for posterior oblique (left posterior oblique [LPO]/right posterior oblique [RPO]) positions of the cervical spine? - answer - 15 degrees cephalad T2-3 intervertebral disk space is found: - answer - Level of jugular notch The chin is extended for a lateral projection of the cervical spine to: - answer - prevent superimposition of the mandible upon the spine. The zygapophyseal joints for the typical cervical vertebra lie at an angle of ____ in relation to the midsagittal plane. - answer - 90 degrees Along with increasing the source-image receptor distance (SID), what other factor(s) will improve spatial resolution for lateral and oblique projections of the cervical spine? - answer - Using a small focal spot What type of CR angulation is required for the AP axial projection for the cervical spine? - answer - 15-20 degrees cephalad A patient comes to the radiology department for a cervical spine routine. The study is ordered for nontraumatic reasons. The AP open mouth projection reveals that the base of the skull and upper incisors are superimposed, but they are obscuring the upper portion of the dens. On the repeat exposure, what should the technologist do to demonstrate the upper portion of the dens? - answer - do fuchs or judd The xiphoid process corresponds to the vertebral level of: - answer - T9-10 A patient comes to radiology for a follow-up study of the cervical spine. The patient had spinal fusion between C5 and C6 performed 6 months earlier. His physician wants to assess the cervical spine for anteroposterior mobility. Which of the following projections would provide this assessment? - answer - Hyperflexion and hyperextension projections When viewed from the side, the vertebral column should present how many curves? - answer - four Along with the upper incisors, what other bony landmark must be aligned for the AP open-mouth projection? - answer - base of skull The bony structures connected directly to the vertebral body are the: - answer - pedicles A patient enters the emergency department (ED) because of a motor vehicle accident (MVA). The patient is on a backboard and wearing a cervical collar. The technologist is concerned about the artifacts that the collar will project on the spine during the horizontal beam lateral projection. What should the technologist do in this situation? - answer - leave collar on What is the central-ray angle for the PA axial oblique projection of the cervical intervertebral foramina? - answer - 15 to 20 degrees caudad Which of the following projections will project the dens within the shadow of the foramen magnum? - answer - AP projection (Fuchs) A radiograph of an AP axial projection of the cervical spine reveals that the intervertebral joints are not open. The following analog factors were used for this projection: 5° cephalad angle, 40-inch (100-cm) SID, grid, slight extension of the skull, and the CR centered to the thyroid cartilage. Which of the following modifications should
