Neurodiagnostic Laboratory

MR Angiography
MRI technology used to visualize blood vessels.

MR Spectroscopy
Uses MRI technology to provide information on organ function.

Nerve Conduction Velocity Studies
Analyzes electrical the electrical currents that deliver messages from the brain to other parts of the body to determine how these currents are altered by injury, inflammation or disease.

Neurosensory Testing
Sensory testing of visual, auditory and somatosensory systems

Polysomnography
Continuous monitoring of normal and abnormal pyshiological activity during sleep. Various functions – brain waves, eye movements, muscle activity, heartbeat, oxygen level and respiration – are all recorded in a single report.

PET Scan, or Positron-Emission Tomography
Produces three-dimensional images that reflect the metabolic and chemical activity of tissues being studied. It is based on the detection of positively charged particles that are emitted by substances introduced into the body.

SPECT scan, or Single Photon Emission Computed Tomography
Used for studying the function of specific organs. A radioactive substance is introduced into the body and accumulates in the target organ and is then recorded to create an image. Cross sectional images are then constructed by a computer.

Transcranial Doppler Ultrasonagraphy
Uses the Doppler effect to visualize information about blood flow within the skull.

Wada Test
A test used to determine whether the right or left hemisphere of the brain is dominant for producing speech.
