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


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



- 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


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


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


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



-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


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


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


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
