Question 1

Oblique radiographs of the lumbar spine are used to visualize the intervertebral foramina.

Accepted Answer

Oblique radiographs of the lumbar spine are primarily used to visualize the facet joints and the pars interarticularis, not the intervertebral foramina.

Question 2

A &#34;standard&#34; series of lumbar radiographs would include _____________ projections.&#10;A) anteroposterior and lateral&#10;B) anteroposterior, lateral, and obliques&#10;C) anteroposterior, lateral, obliques, and a lateral L5-S1&#10;D) anteroposterior, lateral, and a lateral L5-S1

Accepted Answer

A standard series of lumbar radiographs typically includes anteroposterior and lateral projections to assess the lumbar spine.

Question 3

Which of the following is NOT a plane used for lumbar cross-sectional imaging?&#10;A) Axial&#10;B) Coronal&#10;C) Sagittal&#10;D) Oblique

Accepted Answer

The oblique plane is not typically used for lumbar cross-sectional imaging. Axial, coronal, and sagittal planes are the standard planes used for viewing anatomical structures in cross-section, especially in imaging techniques like MRI and CT scans. The oblique plane, while useful in certain contexts, is not a standard plane for lumbar imaging.

Question 4

A lateral lumbar radiograph reveals a 37% anterior slippage of L5 on S1. How would this spondylolisthesis be graded?&#10;A) Grade 1&#10;B) Grade 2&#10;C) Grade 3&#10;D) Grade 4

Accepted Answer

Spondylolisthesis is graded based on the percentage of slippage. A 37% slippage corresponds to Grade 2, which is defined as 26-50% slippage.

Question 5

A lumbar radiograph reveals end plate osteophytosis and vacuum disc phenomenon. What diagnosis would be representative of these findings?&#10;A) Degenerative joint disease&#10;B) Spondylosis&#10;C) Degenerative disc disease&#10;D) Diffuse idiopathic skeletal hyperostosis

Accepted Answer

The vacuum disc phenomenon and end plate osteophytosis are indicative of degenerative disc disease, which involves the degeneration of intervertebral discs and associated changes in the spine.

Question 6

If the base of a herniated disc is narrower than the apex, it is defined as:&#10;A) Prolapsed&#10;B) Protruded&#10;C) Extruded&#10;D) Herniated

Accepted Answer

Extruded discs are characterized by the base being narrower than the apex, indicating that the disc material has extended out beyond the confines of the disc space more at one point than at its base.

Question 7

&#34;Bamboo spine&#34; is the hallmark radiographic finding of this disorder.&#10;A) Spondylosis deformans&#10;B) Ankylosing spondylitis&#10;C) Diffuse idiopathic skeletal hyperostosis&#10;D) Central canal stenosis

Accepted Answer

"Bamboo spine" is a term used to describe the radiographic appearance of the spine in advanced ankylosing spondylitis, where the vertebrae appear fused and rigid, resembling a bamboo stick.

Question 8

&#10;&#10;-Refer to the figure. Name the view.&#10;A) Anteroposterior view of the lumbar spine&#10;B) Anteroposterior view of the lumbosacral spine&#10;C) Oblique view of the lumbosacral spine&#10;D) Lateral view of the lumbosacral spine

Accepted Answer

Question 9

&#10;&#10;-Refer to the figure. What abnormality is present at L5-S1?&#10;A) Spondylolisthesis&#10;B) Spina bifida&#10;C) Spondylosis&#10;D) Scoliosis

Accepted Answer

Spondylolisthesis is the correct answer because it refers to the forward slippage of one vertebra over the one beneath it, which is a common occurrence at the L5-S1 level.

Question 10

&#10;&#10;-Refer to the figure. Name the image and pathological condition.&#10;A) Sagittal MRI, stenosis&#10;B) Axial MRI, vertebral compression&#10;C) Sagittal CT, spondylolisthesis&#10;D) Axial CT, stenosis
