|
Babinski's reflex |
Tested by stroking the sole of the foot, beginning at midheel and moving upward and lateral to the toes |
|
|
|
Brain scan |
A nuclear counter scanning of cranial content two hours after an IV injection of radiostopes |
|
|
|
Cerebral angiography |
Visualization of the cerebral vascular system via x-ray after the injection of radiopaque contrast medium into an arterial blood vessel |
|
|
|
Cerebrospinal fluid analysis |
CSF obtained from a lumbar puncture is analyzed for the presence of bacteria, blood, or malignant cells as well as for the amount of protein and glucose present |
|
|
|
CT scan of the brain or CAT scan |
The analysis of a three-dimensional view of brain tissue obtained as x-ray beams pass through successive horizontal layers of the brain |
CT - computed tomography CAT - computerized axial tomography |
|
|
Chordotomy |
A neurosurgical procedure for pain control accomplished through a laminectomy, in which there is surgical interference of pathways within the spinal cord that control pain |
Chord/o = string, cord -tomy = incision into |
|
|
Cisternal puncture |
Involves insertion of a short, beveled spinal needle into the cisterna magna (a shallow reservoir of CSF between the medulla and the cerebellum) to drain CSF or to obtain a CSF specimen |
|
|
|
Craniotomy |
A surgical procedure that makes an opening into the skull |
|
|
|
Echoencephalography |
Ultrasound used to analyze intracranial structures of the brain |
Echo = sound Encephal/o = brain -graphy = process of recording |
|
|
Electroencephalography (EEG) |
Measurement of electrical activity produced by the brain and recorded through electrodes placed on the scalp |
|
|
|
Electromyography (EMG) |
Process of recording the electrical activity of muscle by inserting a small needle into the muscle and delivering a small current that stimulates the muscle |
|
|
|
Laminectomy |
The surgical removal of the bony arches from one or more of the vertebrae to relieve pressure on the spinal cord |
Lamin/o = lamina -ectomy = surgical removal |
|
|
Lumbar puncture |
Involves the insertion of a hollow needle and stylet into the subarachnoid space, generally between the 3rd and 4th lumbar vertebrae below the level of the spinal cord under strict aseptic technique |
|
|
|
Magnetic resonance imaging (MRI) |
A noninvasive scanning procedure that provides visualization of fluid, soft tissue, and bony structures without the use of radiation |
|
|
|
Myelography |
Involves an introduction of a contrast medium into the lumbar subarachnoid space through a lumbar puncture to visualize the spinal cord and vertebral canal through x-ray examination. |
|
|
|
Neurectomy |
A neurosurgical procedure to relieve pain in a localized or small area by incision of cranial or peripheral nerves |
|
|
|
Pneumoencephalography |
Used to visualize radiographically one of the ventricles or fluid-occupying spaces in the CNS |
Pneum/o = kungs, air Encephal/o = brain -graphy = process of recording |
|
|
Polysomnogram |
A sleep test that evaluates physical factors affecting sleep. Physical activity and level of sleep are monitored by a technician while the patient sleeps |
Poly = many Somn/o = sleep -gram = record or recording |
|
|
Positron emission tomography (PET) |
A scan that produces computerized radiographic images of various body structures when radioactive substances are inhaled or injected |
|
|
|
Romberg test |
Used to evaluate cerebellar function and balance |
|
|
|
Stereotaxic neurosurgery |
Surgery on a precise location of an area within the brain that controls specific functions and may involve destruction of brain tissue with various agents such as heat, cold, and sclerosing or corrosive fluids |
|
|
|
Sympathectomy |
A surgical procedure used to interrupt a portion of the sympathetic nerve pathway for the purpose of relieving chronic pain |
|
|
|
Transcutaneous electrical nerve stimulation (TENS) |
A form of cutaneous stimulation for pain relief that supplies electrical impulses to the nerve endings of a nerve close to the pain site |
|
