1

Cerebral Angiography

- invasive procedure that can determine that narrowing or blockage of an artery within the brain

-used when Dx a potential CVA, brain tumors, aneurysm or vascular malformation

-Catheter threaded up through the body into an artery within the nex and contrast dye is released into the bloodstream. Series of X-rays are taken

2

Computed tomography (CT scan)

-Brain scan imaging (non-invasive)

-Provides cross sections of the area tested with precise two dimensional views of bones, tissues, and organs

-Dyes or contrast are occasionally used to provide the best view of any pathology that may exist within the tissues

-CT scan of brain/SC may rule out vascular malformations, tumors, cysts, herniated disks, hemorrhage, epilepsy, spinal stenosis, intracranial bleeding, and head injury

3

Discography

- invasive procedure to evaluate the integrity and pathology of a spinal disk

-Contrast dye is injected an CT scanning is performed in order to better assess suspected damaged areas of intervertebral disks

4

Electroencephalography (EEG)

-non-invasive procedure that can continuously measure electrical activity of the brain using multiple electrodes attached to the skull

-Baseline electrical activity is determined, and then various stimuli presented and brain waves are analyzed

-An EEG used to rule out seizure disorders, brain death, brain tumors, brain damage, inflammation, alcoholism, select psychiatric disorders, and degenerative disorders that affect the brain

5

Electromyography (EMG)

Invasive procedure that is used to assess nerve and muscle dysfunction or spinal cord disease

-Records electrical activity from the brain or spinal cord to the peripheral nerve root being tested

-EMG rules out muscle pathology, spinal cord disease, denervated muscle, LMN injury

6

Magnetic resonance imaging (MRI)

-Brain scan imaging that is typically non-invasive and provides detailed images including tissues, organs, bones, and nerves.

- A contrasts dye may be used to enhance imaging of certain tissues

- MRI rules out tumors of the brain or spinal cord, MS, and head trauma

7

Myelography

-Invasive procedure of the spinal canal using contrast dye and x-ray imaging

-The procedure has a high risk for headache following the spinal tap

- Used to rule out potential abnormalities surrounding the subarachnoid space, spinal nerve injury, herniated disks, fractures, back or leg pathology and spinal tumors

8

Nerve Conduction Velocity (NVC)

-Non-invasive stimulation of a peripheral nerve to determine the nerve action potentials and the nerve’s ability to send a signal

-Rules out peripheral neuropathies, carpal tunnel syndrome, demyelination pathology, and peripheral nerve compression

9

Positron emission tomography (PET)

-Brain scan imaging that provides two and three dimensional pictures of brain activity

-used to rule out cerebral Circulatory pathology, metabolism dysfunction, tumors, blood flow, and Brian changes following injury or drug abuse

10

Spinal Puncture (lumbar)

-Invasive procedure that inserts a needle through lumbar puncture below the level of L1-L2 form cerebral spinal fluid sample

-most commonly performed at the L3-L4 level

-rules out hemorrhage, inflammation, infection, meningitis, tumor
