Q

electroencephalogram

A

record of the minute electrical impulses of the brain

1
Q

electrodiagnostic procedures

A

evaluation of the nervous systems by recording electrical signals produced in the CNS & PNS

2
Q

evoked potentials

A

record of electrical potentials (waves) that are extracted from ongoing EEG activity to diagnose auditory, visual, and sensory pathway disorders; also used to monitor patients during surgery

3
Q

polysomnography

A

recording of various aspects of sleep to diagnose sleep disorders

4
Q

lumbar puncture (LP)

A

spinal tap; extraction of CSF from lumbar spine for diagnostic purposes

5
Q

magnetic resonance imaging (MRI)

A

non-ionizing imaging technique used to visualize soft tissues such as the brain and spinal cord

6
Q

magnetic resonance angiography (MRA)

A

MRI of blood vessels to detect pathologic conditions

7
Q

intracranial MRA

A

MRI of the head to visualize the circle of Willis

8
Q

extracranial MRA

A

MRI of the neck to visualize the carotid artery

9
Q

nuclear medicine imaging

A

radionuclide organ imaging

10
Q

single-photon emission computed tomography (SPECT) brain scan

A

scan combining nuclear medicine and CT to produce images of the brain after administration of radioactive isotopes

11
Q

positron-emission tomography (PET)

A

technique combining nuclear medicine and CT to produce images of the brain anatomy and corresponding physiology

12
Q

radiography

A

x-ray imaging

13
Q

cerebral angiogram

A

x-ray of the blood vessels of the brain after introducing a contrast medium

14
Q

computed tomography (CT) of the head

A

CT of the head to visualize abnormalities, such as tumors and malformations

15
Q

myelogram

A

x-ray of the spinal cord obtained after administering a contrast medium

16
Q

reflex testing

A

test performed to observe the body’s response to a stimulus

17
Q

deep tendon reflexes (DTR)

A

involuntary muscle contraction after percussion at a tendon, indicating function. Positive findings are rated 0-4

18
Q

Babinski sign or reflex

A

pathologic response to stimulation of the plantar surface of the foot; a positive sign is when the toes dorsiflex

19
Q

transcranial Doppler sonogram

A

image made by sending ultrasound beams through the skull to assess blood flow in intracranial vessels
