Transcranial Doppler (TCD) is a non-invasive ultrasound technique used to measure the velocity of blood flow in the major cerebral arteries. It is particularly useful in assessing blood flow dynamics in the brain, helping to diagnose and monitor various neurological and vascular conditions. \#\#\# Key Features of Transcranial Doppler: 1. **Principle**: TCD utilizes the Doppler effect, which involves the change in frequency of ultrasound waves as they reflect off moving red blood cells.
