LRA 223, 224 final study review questions 100% correct
Question :On average, how many separate bones make up the
adult vertebral column?
CORRECT ANSWER :26
Question :The gonion corresponds to the level of?
CORRECT ANSWER :C3
Question :A radiograph of an AP open-mouth projection
reveals that the base of the skull is superimposed over the dens. What positioning error led to this radiographic outcome?
CORRECT ANSWER :Excessive skull extension
Question :What is the name of the fracture that results from
hyperflexion of the neck, results in avulsion fractures on the spinous processes of C6 through T1. The fracture is best demonstrated on a lateral cervical spine radiograph.
CORRECT ANSWER :Clay Shoveler's Fracture
Question :This condition is inflammation of the vertebrae.
CORRECT ANSWER :Spondylitis
Question :Identify landmark labeled "c"
CORRECT ANSWER :Iliac Crest (L4-5)
Question :What type of CR angulation is required for an AP
axial projection of the coccyx?
CORRECT ANSWER :10 degrees caudad
Question :A patient comes to radiology for a follow-up study
for a Clay Shoveler's fracture. What projection will best demonstrate the extent of this fracture?
CORRECT ANSWER :Lateral cervical spine projection
Question :Which specific aspect of the sacrum articulates
with the ilium to form the sacroiliac joints?
CORRECT ANSWER :Auricular surface
Question :Identify the projection on this radiograph.
CORRECT ANSWER :AP axial sacrum
Question :A radiograph of a lateral projection of the lumbar
spine reveals that the mid-to lower-intervertebral joint spaces are not open. The patient's waist was supported. Which modifications will help open joint spaces during the repeat exposure?
CORRECT ANSWER :Increase waist support and/or angle
CR 5 to 8 degrees caudal.
Question :A radiograph of an AP open-mouth projection of
the cervical spine reveals that the zygapophyseal joints are not symmetric. No fracture or subluxation is present. Which one of the following positioning errors most likely led to this radiographic outcome?
CORRECT ANSWER :Rotation of the spine.
Question :A congenital condition in which the posterior
aspects of the vertebrae fail to develop, thus exposing part of
the spinal cord. This condition varies greatly in severity and occurs most often at L5.
CORRECT ANSWER :Spina Bifida
Question :A radiograph of a lateral thoracic spine reveals that
there is excessive density along the posterior aspect of the spine. Even with good collimation, the scatter radiation reaching the image receptor obscures the spinous processes.What can the technologist do to improve the visibility of the post?
CORRECT ANSWER :Place a led mat posterior to the spine.
Question :Which of the thoracic vertebra(e) poses no facets
for costrotransverse joints?
CORRECT ANSWER :T11-T12
Question :A patient comes to radiology for a follow-up study
of the lumbar spine. The patient had a spinal fusion performed at the L3-4 level 4 months earlier. Which of the following would best demonstrate the degree of movement at the fusion site?
