Spinal imaging

Question 1

Answer 1

corona;

Question 2

The ideal scan plane in spine imaging for evaluation of the degree of posterior disc herniation as well as intervertebral disc height would be:

Answer 2

sagittal

Question 3

During a post surgical MRI of the lumbar spine, the evaluation of post operative surgical regions and/or the possibility of scar tissue can be best accomplished by:

Answer 3

Sagittal slice plane; T1 weighted post gadolinium

Question 4

The ligamentum flavum can be found in which part of the body?

Answer 4

Spine

Question 5

On T1 weighted images of the spine, the CSF (cerebrospinal fluid) appears:

Answer 5

Hypointense to the spinal cord

Question 6

The cauda equina and the conus medullaris are best seen with a:

Answer 6

Sagittal image of the lumbar spine

Question 7

On T2 weighted images of the spine, the CSF (cerebrospinal fluid) appears

Answer 7

Hyperintense to the spinal cord

Question 8

: For patients that have undergone surgery for herniated disc in the lumbar spine, gadolinium contrast enhancement can be utilized to distinguish recurrent disc from post-operative scar tissue because:

Answer 8

Disc enhances more slowly than post-operative scar

Question 9

On an image of the thoracic spine in the sagittal plane, utilizing a 28cm FOV, the vertebral disc levels can be determined by:

Answer 9

Using a large FOV localizer and optional vit E markers to count down from C2

Question 10

The __________ is the soft, jelly-like, inner portion of the intervertebral disc.

Answer 10

Nucleus pulposus

Question 11

Which imaging plane would best display both the dorsal and ventral nerve roots?

Answer 11

axial

Question 12

The vertebral body will display a _________ signal intensity on T1 weighted images in the presence of fracture, infection or neoplasm

Answer 12

Hypointense

Question 13

: A condition called ___________ is a condition in which the spinal cord is pulled lower than its natural position and is generally found in children or patients with Chiari Malformation

Answer 13

tethered cord

Question 14

The individual nerve roots that leave the lower portion of the spinal cord and progress downward are termed the __________ or “horse’s tail.”

Answer 14

cuada equina

Question 15

The _____________ is the inferior portion of the spinal cord and is found at the ________ disc level.

Answer 15

Conus medullaris; T12-L1

Question 16

The ______ scan plane best demonstrates the degree of spinal stenosis

Answer 16

Sagittal

Question 17

: If a patient has metal hardware from previous spinal surgery, the ___________ sequence should be avoided due to prominence of susceptibility artifacts.

Answer 17

Gradient echo

Question 18

The __________ is the spinal region that is LEAST affected by cerebrospinal fluid (CSF) pulsation.

Answer 18

Lumbar

: Image 19 is an example of a:

Answer 23

Axial cervical spine

Question 24

Image 53 is an example of:

Answer 24

T2 Sag thoracic spine

Question 25

An indication for injecting a patient with Gadolinium contrast for an MRI of the lumbar spine would be:
