Transcranial Doppler Ultrasound Pulsatility Index: Utility and Clinical Interpretation

  • Chapter
  • First Online:
Neurosonology in Critical Care

Abstract

Transcranial Doppler (TCD) and transcranial color-coded duplex sonography (TCCS) are valuable real-time neurologic monitoring tools in the ICU. Pulsatility index (PI) is one of the most important hemodynamic parameters provided by TCD/TCCS, which allows one to assess the cerebral hemodynamic changes in a patient with acute neurological injury. Here, we focus on the clinical utility of PI to guide clinical management.
