Transcranial Doppler can be an essential aid in the study of Cerebrovascular disease.. Our comprehensive and detailed protocol assists in understanding and interrogating a wide variety of neurovascular pathology such as:

  1. Carotid stenosis/occlusion
  2. Arteriovenous Malformations
  3. Cerebral Vasospasm
  4. Cerebral Emboli Detection
  5. Reduced/Absent Cerebral
  6. Intracranial Stenosis
  7. Diminished Vasomotor Reactivity
  8. Head Trauma
  9. Autoregulation
  10. Variations in Circle of Willis
  11. Cerebral Circulatory Arrest

TCD is noninvasive, relatively inexpensive, portable and fairly easy to use. It allows continuous monitoring and frequent repeated measurements. Immediate, real time detection of changes in cerebrovascular hemodynamics is readily apparent. It can be utilized by virtually all medical specialties to evaluate many neurovascular disorders.


In many areas, especially rural ones, there are a lack of neurologists and/or MRI machines available for appropriate stroke workup. In these settings a complete stroke workup will consist of carotid Doppler and two-dimensional echocardiogram. These are essential in the diagnosis of Cardiovascular Disease, but they will miss the essential evaluation of intracranial vasculature when stroke is suspected. A TCD can provide an inexpensive, simple means to determine which patients must be referred to Centers specializing in Cerebral Vascular Incidents for further evaluation. In addition, for those patients who decline intervention initially, TCD gives the Healthcare Provider a tool for monitoring the identified lesions and evaluate the effectiveness of employed medical treatments.

Finally, TCD may be the only mean available to evaluate intracranial vessels in cases when alternate radiographic means are contraindicated. TCD is a blind procedure; its accuracy relies on the extensive knowledge and experience of a properly trained technician and interpreter.
