TCD (Transcranial Doppler) Screening

Transcranial Doppler (TCD) screening is a non-invasive ultrasound technique that measures blood flow in the brain’s major arteries. By sending sound waves through the skull, it helps detect abnormalities such as narrowed or blocked vessels, which can indicate risks for strokes or other cerebrovascular conditions. It’s a quick, painless test often used in high-risk patients, including those with sickle cell disease or diagnosed with stroke risk factors. TCD provides real-time information about blood flow dynamics, aiding in early diagnosis and guiding treatment to prevent serious brain events.
