Doppler/Duplex Ultrasound of Cerebral Vessels (extracranial, intracranial, and transcranial)

Doppler/duplex ultrasonography is used to diagnose vascular diseases and assess stroke risk. Ultrasound identifies vessel narrowings (e.g., carotid and cerebral arteries) and atherosclerotic changes in vessel walls.

The examination is done both extracranially (outside the skull) and intracranially (inside the skull). The transducer is placed on the neck and head to obtain real time images, measuring blood flow speed and direction. This helps detect anomalies or blockages compromising cerebral blood supply.

State of the art German ultrasound equipment is used for high resolution imaging of even the slightest wall abnormalities. The procedure takes approximately 10–20 minutes.

When it’s indicated:

• Headache, dizziness, or brief loss of consciousness
• One sided limb numbness or speech disorders
• High blood cholesterol
• Noticeable pulse in the neck
• Unexplained, persistent neck pain
• After vascular surgery or interventions
• For stroke prevention screening, especially from age 40
