Flashcards in Ch. 8 Diagnostic Tests & Procedures Deck (20):
0

electrodiagnostic procedures

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

1

electroencephalogram

record of the minute electrical impulses of the brain

2

evoked potentials

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

polysomnography

recording of various aspects of sleep to diagnose sleep disorders

4

lumbar puncture (LP)

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

5

magnetic resonance imaging (MRI)

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

6

magnetic resonance angiography (MRA)

MRI of blood vessels to detect pathologic conditions

7

intracranial MRA

MRI of the head to visualize the circle of Willis

8

extracranial MRA

MRI of the neck to visualize the carotid artery

9

nuclear medicine imaging

radionuclide organ imaging

10

single-photon emission computed tomography (SPECT) brain scan

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

11

positron-emission tomography (PET)

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

12

radiography

x-ray imaging

13

cerebral angiogram

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

14

computed tomography (CT) of the head

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

15

myelogram

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

16

reflex testing

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

17

deep tendon reflexes (DTR)

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

18

Babinski sign or reflex

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

19

transcranial Doppler sonogram

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