Review board

All the following are types of pulse sequences currently used in MRI Neurography (peripheral nerve) except:

DTI/Tractography

STIR/T2 FS

Proton density TSE

T1 TSE

What spine area will require a larger FOV to cover the entire anatomy?

Cervical

Thoracic

Lumbar

Sacral

In a complete spine imaging, to rule out metastatic lesions of the spinal cord, contrast enhancement can be used with T1 weighted images because:

Normal cord enhances and metastatic lesions do not

Metastatic lesions enhance and normal cord does not

Scar enhances and disk does not

Which areas of the spine are the most important to scan in a patient diagnosed with Multiple sclerosis?

Cervical & Lumbosacral

Thoracic & Lumbosacral

Cervical & Thoracic

Which imaging option will help visualize lesions such as fractures and metastasis within the bone marrow of the vertebral bodies?

T1 FAT SAT

T2 FSE

STIR

T1

On an image of the thoracic spine in the sagittal plane, the vertebral disc levels can be determined by:

Using small dipole magnets to move isocenter to the spine

Using the sternal notch as a landmark and counting from T1

Using a large FOV localizer and optional skin marker to count down from C2

Using lead mammo markers over the xiphoid

Axial images of the spine should be acquired:

Perpendicular to the disc

Parallel to the spinal cord

Perpendicular to the vertebral body

Parallel to the inter-vertebral disc space

In the case of susceptibility artifacts due to spine hardware. What is the pulse sequence that reduces the susceptibility effect the most?

STIR

FSE

GRE

SE

When an inter-vertebral disc appears dark in a T2 weighted image, it might be an indication of:

Swalen disk

Disk IV contrast enhancement

Healthy disc

Disk dehydration

For cervical spine patient positioning, optimal patient orientation should be __________ and the coil should be positioned ________ between the levels C1-C7.

Supine; anterior to patient

Supine; posterior to patient

Prone; anterior to patient

Prone; posterior to patient

Fat saturation after contrast administration will be more beneficial when scanning the

Intra-axial lesions

Spinal cord for MS plaques

Bone marrow infiltrating process

All of the above

On an image of the thoracic spine in the sagittal plane, the vertebral disc levels can be determined by:

Using small dipole magnets to move isocenter to the spine

Using the sternal notch as a landmark and counting from T1

Using a large FOV localizer and optional skin marker to count down from C2

Using lead mammo markers over the xiphoid

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

Isointense to the spinal cord

Hypointense to the spinal cord

Hyperintense to the spinal cord

None of the above

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

HNP

Bulging disk

Laminectomy

Appendectomy

In bright fluid, axial images of the cervical spine, pulsatile flow from CSF can cause flow artifacts on the image. Which of the following techniques help to reduce flow artifact in axial images of the spine?

T2*

T2 long ETA

Superior and inferior pre-saturation bands

All of above

A syrinx is a pathology observed mostly in the spinal cord. A syrinx is:

An abnormal accumulation of myelin in the spinal cord

A separation of the spinal cord filled with CSF

A localize atrophy of the spinal cord

The downward of the spinal cord

Which of the following can be a consequence of Chiari Malformation?

Tethered cord

Arachnoiditis

Syrinx

Meningocele

There are ___ pairs of spinal nerves along the entire spine.

7

12

31

62

A complete spinal cord transection at the level of C4 can result in:

Hemiplegia

Paraplegia

Quadriplegia

All of the above

Paraplegia is defined as paralysis of:

one side of the body

two lower limbs

four limbs
