Nerve System: Diagnostic, Surgical, and Therapeutic Procedure

Question 1

CTA, CT angiography
computed tomography angiography

Answer 1

radiographic image of the interior of a vessel in combination with a CT scan to produce high-resolution, three-dimensional images of blood vessels

Question 2

discography

Answer 2

CT scan of the lumbar region after injection of a contrast medium to detect problems with the spine and spinal nerve roots

Question 3

MSI
magnetic source imaging

Answer 3

noninvasive neuroimaging technique to pinpoint the specific location where seizure activity originates and enable custom surgical treatment for tumor epileptic tissue resection
- also called (MEG)
magnetoencephalography

Question 4

PET
positron emission tomography

Answer 4

computed tomography that records the positrons emitted from a radiopharmaceutical and produces a cross-sectional image of metabolic activity of body tissues to determine the presence of disease

Question 5

thalamotomy

Answer 5

partial destruction of the thalamus to treat intractable pain; involuntary movements, including tremors in Parkinson disease; or emotional disturbances

Question 6

ventriculoperitoneal shunting

Answer 6

relieves intracranial pressure due to hydrocephalus by diverting (shunting) excess cerebrospinal fluid from the ventricles into the peritoneal or thoracic cavity

Question 7

intravenous (IV) tissue plasminogen activator (tPA)

Answer 7

treatment for ischemic stroke using tissue plasminogen activator (tPA), a potent clot-busting drug, injected directly into a vein

Question 8

SRS
stereotactic radiosurgery

Answer 8

procedure that uses three-dimensional imaging (stereotactic) along with high doses of highly focused radiation to destroy tumors and other abnormal growths in the brain, spinal column, and other body sites with minimal exposure to surrounding healthy tissue
