Answer 4

None

Question 5

Answer 6

Bone: 2500/600
Standard: 400/40

Question 7

Question 11

Spinal cord impingement may be related to (5)…

Answer 11

Fracture
Disc Injuries
Arthritic Ds
Spinal Tumor
Spondylolisthesis

Question 12

CT Myelogram: Indications (4)

Answer 12

Pain/Numbness
Injury
Radiculopathy
Suspected/Known impingement of spinal cord or spinal nerves

Question 13

CT Myelogram: Scan Type

Answer 13

Helical

Question 14

CT Myelogram: Slice Parameters

Answer 14

1.25mm w/matching interval

Question 15

CT Myelogram: Gantry Tilt

Answer 15

None

Question 16

CT Myelogram: Contrast
Site
Patient Instructions

Answer 16

ITh only in subarachnoid space
Pt must roll several times prior to scanning to ensure even diffusion

Question 17

CT Myelogram: Algorithm

Answer 17

Bone or “Detail”: 2100/700

Question 18

CT Myelogram: Reformations

Answer 18

Coronal/Sagittal MPR from thinnest data set
Axial of individual disc spaces may provide better visualization of spinal canal (allows axial slices perfectly parallel to the position of the intervertebral disc)

Question 19

CT Spine: C-Spine Slice Parameters

Answer 19

1.25mm w/matching interval

Question 20

CT Spinal Tumor Imaging

Answer 20

MRI for tumors

Question 21

CT Spinal Infection Imaging

Answer 21

MRI preferred

Question 22

CT Spine: C-Spine Slice Thickness

Answer 22

1.25mm

Question 23

CT Spine: IV Contrast

Answer 23

(done as WWO)
Only when MRI contraindicated

Question 24

CT Spine: Contrast

Answer 24

ITh only, unless MRI contraindicated

Question 25

CT Spine: Utility of Std Algorithm

Answer 25

Visualize changes to the ST surrounding injury (muscles, ligaments, spinal cord)

Question 26

CT Myelogram: Axial MPR utility

Answer 26

Axial of individual disc spaces may provide better visualization of spinal canal (allows axial slices perfectly parallel to the position of the intervertebral disc)
