Medical Procedures/Testing For Neurological Dysfunction

Question 1

Cerebral Angiography

Answer 1

Invasive
Determines narrowing/blockage in artery within brain
Catheter in neck artery for contract dye then X-rays taken

Question 2

Computed tomography (CT scan)

Answer 2

Non-invasive

Brain scan providing cross sections of area, dyes possible

Question 3

Discography

Answer 3

Invasive
Determines integrity/patho of spinal disk
Contract dye then CT scan

Question 4

Electroencephalography

Answer 4

Non-invasive

Electrical activity of brain using electrodes, baseline determined then stimuli presented

Question 5

Electromyography (EMG)

Answer 5

Invasive
Assesses nerve/muscle/spinal cord dysfunction
Electrical activity from brain/spinal cord to peripheral nerve

Question 6

Evoked potentials

Answer 6

Noninvasive

time it takes for impulse to reach brain with two electrodes

Question 7

Magnetic resonance imaging (MRI)

Answer 7

Noninvasive

Imaging with possible contrast dye

Question 8

Myelography

Answer 8

Invasive
Spinal tap of spinal canal with contrast dye and X-ray
*High risk of HAs

Question 9

Nerve conduction velocity (NCV)

Answer 9

Noninvasive

Stimulation of peripheral nerve to determine nerve action potentials and ability to send a signal

Question 10

Positron emission tomography (PET)

Answer 10

Noninvasive

Brain scan imaging 2/3D imaging

Question 11

Spinal puncture (lumbar)

Answer 11

Invasive
Lumbar puncture at L1-2 for CSF sample
*commonly done at L3-4
