CHP10. (Laboratory tests and clinical procedures)

cerebrospinal fluid analysis

samples of CSF (cerebrospinal fluid) are examined

cerebral angiography

X-ray imaging of the arterial blood vessel in the brain after injection of contrast material

computed tomography (CT) of the brain

X-ray technique that generates computerized multiple images of the brain and spinal cord

myelography

X-ray imaging of the spinal canal after injection of contrast medium into the subarachnoid space.

Magnetic resonance imaging (MRI)

Magnetic field and pulses of radiowave energy create images of the brain and spinal cord.

Positron emission tomography (PET) SCAN

Radioactive glucose is injected and then detected in the brain to image the metabolic activity of cells

Doppler ultrasound studies

sound waves detect blood flow in the carotid and intracranial arteries

electroencephalography (EEG)

Recording of the electrical activity of the brain

lumbar puncture (LP)

CSF (cerebrospinal fluid) is withdrawn from between two lumbar vertebrae for analysis

sterotactic radiosurgery
