LRA 223, 224 final study review questions
100% correct detailed verified answers
latest update 2025
16. 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?--- correct answer --- Lateral
hyperextension/flexion
17. The average degree of rotation required to demonstrate the L3-4
zy- gapophyseal joints is--- correct answer --- 45 degrees
18. Along with the upper incisors, what other bony landmark must
be aligned for the AP open-mouth projection?--- correct answer ---
Base of the skull
19. A lateral projection of the thoracic spine reveals that the upper
aspect, which is a primary area of interest on this patient, is obscured
by the patient's shoulders. Which of the following changes will best
demonstrate this region of the spine?--- correct answer --- Perform a
cervicothoracic (swimmer's) lateral position.
20. What structure is located at the level of the ASIS?--- correct
answer --- S1-2
21. The AP open-mouth projection is taken for trauma evaluation. It
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 alternative view can be done?--- correct answer ---
Fuchs or Judd
22. The bony structures connected directly to the vertebral body are-
-- correct answer --- Pedicles
23. A hyperflexion force that causes fracture through the vertebral
body and posterior elements. Patients wearing lap-type seat belts are
at risk because these belts act as a fulcrum during sudden
deceleration.--- correct answer --- Chance Fractures
24. Identify the pathology in this radiograph of the lumbar spine---
correct answer ---
Fracture
25. How much obliquity is required for posterior positions for the
sacroiliac joints?--- correct answer --- 25-30 degrees
26. What level does the jugular notch correspond with?--- correct
answer --- T2-T3
27. What term describes the normal concave curvature of the lumbar
spine or an exaggerated concave lumbar curvature?--- correct answer
--- Lordosis
28. The joints between articular processes of vertebra are termed
joints.--- correct answer --- Zygapophyseal joints
29. Evaluate the oblique lumbar spine image--- correct answer ---
The pedicles are too p the vertebral body, rotate the patient less.
