 About Transcranial Doppler Study (TCD Test or TCD Study)

What is a Transcranial Doppler Study?

A transcranial doppler study uses soundwaves to create an image of the brain. The word 'doppler' refers to a special technique where the source of the sound waves, in this case, the doppler wand, is moving. The word 'transcranial' means that the test is looking inside the brain. 

The test is performed using only an ultrasound wand attached to a computer that creates images based on the sound waves bouncing off the blood vessels. Human ears are not capable of detecting ultrasound waves like those used in an arterial doppler. Still, they're just sound waves. That's why it's safe to use ultrasound waves during prenatal checkups. Just like the brain of a dolphin, the computer attached to the ultrasound wand creates an image based on the tiniest echoes that the sound waves cause. Then your cardiologist or vascular specialist can see where your arteries contain hardened plaque, if you have a blood clot, or where the arteries have been damaged. 

Why do I need a Transcranial Doppler?

Transcranial doppler studies are generally done to detect and diagnose an embolism (a blockage inside a blood vessel in the head) or stenosis (narrowing and hardening of a blood vessel). While those are the most common reasons we perform such tests, they can be used to detect and diagnose several other diseases that affect the brain. 

If you have already been diagnosed with a specific condition, you may need to continue regular transcranial doppler exams to make sure your treatment is working correctly. 

 What are the Risks of a Transcranial Doppler?

A transcranial doppler scan, like all scans that use ultrasound waves, is completely non-toxic, non-invasive, and painless. Your vascular doctor can use this type of test as often as necessary. It's so safe it can be performed on newborn and unborn babies.
