Q

DIAGNOSTIC STUDIES (Identify what department belongs to):

  1. CSF is aspirated by needle
    insertion in L3-4 or L4-5
    interspace to assess many CNS diseases.
  2. Simple x-ray of skull & spinal column is done to detect fractures, bone erosion, calcifications, abnormal vascularity.
  3. Serial X-ray visualization of intracranial & extracranial
    blood vessels is performed to detect vascular lesions &
    tumors of brain. Contrast
    medium is used.
  4. Computer-assisted x-ray of multiple cross sections of body parts to detect problems such as hemorrhage, tumor, cyst, edema, infarction, brain
    atrophy, & other abnormalities. Contrast media may be used to
    enhance visualization of brain structures.
  5. Imaging of brain, spinal cord & spinal canal by means of magnetic energy.
    - Has greater contrast in
    images of soft tissue structures than CT scan.
  6. Uses differential signal
    characteristics of flowing blood to evaluate extracranial &
    intracranial blood vessels.
  7. Measures metabolic activity of brain to assess cell death or damage.
  8. A method of scanning similar to PET, but it uses more stable substances & different detectors.
  9. X-ray of spinal cord & vertebral column after injection of contrast medium into subarachnoid space.
  10. Electrical activity of brain is recorded by scalp electrodes to evaluate seizure disorders, cerebral disease, CNS effects of
    systemic diseases, brain death.
  11. Electrical activity associated with nerve & skeletal muscle is recorded by insertion of needle
    electrodes to detect muscle & peripheral nerve disease.
  12. Combined ultrasound & pulsed doppler technology
  13. Same technology as carotid duplex, but evaluates blood
    flow velocities of the
    intracranial blood vessels.
A
  1. Lumbar puncture (CSF Analysis)
  2. Skull & Spine X-rays
  3. Cerebral Angiography
  4. CT scan (Computed Tomography)
  5. MRI (Magnetic Resonance Imaging)
  6. MRA (Magnetic Resonance Angiography)
  7. PET Scan (Positron Emission Tomography)
  8. SPECT (Single-photon Emission Computed Tomography)
  9. Myelogram
  10. EEG (Electroencephalography)
  11. EMG (Electromyography) & Nerve Conduction Studies
  12. Carotid duplex studies
  13. Transcranial doppler
