DIAGNOSTIC TEST OF NEUROLOGICAL SYSTEM

• Skull and Spinal Radiography - Radiographs of the skull reveal the size and shape of the skull bones; Spinal radiographs identify fractures, dislocation, compression
• Computer Tomography - is a type of brain scanning that may or may not require injection of a dye
• Magnetic Resonance Imaging -

  • is a noninvasive procedure that identifies tissues, tumors, and vascular abnormalities
  • It is similar to CT scanning but provides more detailed pictures
• Lumbar Puncture - Insertion of a spinal needle through the L3-L4 interspace into the lumbar subarachnoid space
• Lateral Recumbent Position - Position in Lumbar Puncture
• Myelography - Injection of dye or air into the subarachnoid space to detect abnormalities of the spinal cord and vertebrae
• Myelography Preprocedure - Provide hydration for at least 12 hours before the test
• Head is Elevated - an oil-based or water-soluble contrast agent is used
• Head positioned lower - head position if air contrast is used
• Cerebral Angiography - Injection of a contrast material usually through the femoral artery (or another artery) into the carotid arteries to visualize the cerebral arteries and assess for lesions
• 2 days - encourage hydration how many days in Cabral angiography
• 4 to 6 hours - how many hours shoul the client maintain as NPO in cerebral angionography
• Electroencephalography - Graphic recording of the electrical activity of the superficial layers of the crebral cortex
• Caloric Testing - provides information about the function of the vestibular portion of the eighth cranial nerve and aids in the diagnosis of cerebellar and brainstem lesions.
• supine with the head of the bed elevated 30 degrees - patient position in caloric testing
