Area of Science:

  • Neurology
  • Medical Imaging
  • Cardiology

Background:

  • Intracranial vessels are crucial for brain function.
  • Assessing blood flow dynamics is vital for diagnosing neurological and cardiovascular conditions.
  • Traditional imaging methods may have limitations in visualizing intracranial hemodynamics.

Purpose of the Study:

  • To evaluate the utility of colour-coded duplex sonography in visualizing intracranial vessels.
  • To demonstrate the application of Doppler technology for quantifying intracranial blood flow.
  • To outline the diagnostic indications for this imaging technique in cerebrovascular and cardiovascular diseases.

Main Methods:

  • Utilizing colour-coded duplex sonography to display intracranial vessels superimposed on grayscale images.
  • Employing pulsed Doppler with a sample volume for optimal placement within vessels.
  • Implementing angle correction for accurate flow velocity quantification.

Main Results:

  • Colour-coded duplex sonography effectively visualizes intracranial vessels.
  • The technique allows for precise placement of the Doppler sample volume.
  • Angle correction enables reliable quantification of intracranial blood flow velocities.
  • Pathologic flow profiles in intracranial arteries are associated with cardiovascular malformations.

Conclusions:

  • Colour-coded duplex sonography is a valuable tool for assessing intracranial vasculature.
  • This method aids in diagnosing conditions like intracranial hemorrhage, hydrocephalus, and cerebrovascular malformations.
  • It also helps identify intracranial hemodynamic changes linked to cardiovascular diseases.
