Transcranial Doppler (TCD) is a non invasive ultrasound technology used to evaluate blood flow velocity in the major basal intracranial arteries.  TCD may be used on its own or in conjunction with other imaging modalities.  A thorough neurovascular exam should include TCD, as carotid obstructions seen with duplex imaging may have significant intracranial effects that should be considered in patient management decisions. Current applications of TCD include:

1. Detection and monitoring of vasospasm following aneurysmal subarachnoid hemorrhage.
2. Screening for basilar artery stenosis.
3. Diagnosis of intracranial stenosis and occlusion.
4. Evaluation of intracranial effects of extracranial stenosis, including assessment of collateral flow pathways.
5. Evaluation of vasomotor reserve.
6. Support of the diagnosis of brain death.
7. Evaluation and monitoring of intracranial blood flow during surgical procedures.
8. Detection of patent foramen ovale.
9. Identification of feeder arteries in AVM's.

The Neurovision™ TCD system has been engineered to meet the distinct requirements of the clinical environment.  Multigon encourages you to browse our website or contact us for more information on transcranial Doppler, teaching aids and training courses.
