A Transcranial Doppler, also known as a TCD, is a non-invasive 10-minute procedure that uses ultrasound technology to measure and chart blood flow within the brain. This painless procedure allows us to evaluate a patient’s risk of stroke, macular degeneration, and diabetes as well as other health conditions.
A TCD is considered extremely safe and can be performed on patients of any age and does not require the usage of dye during the exam.
During the procedure, our technicians place a probe against your temple, and waves are emitted. The ultrasound waves reflected off of moving blood cells within your brain, and the information is recorded and analyzed by a program to determine the characteristics of blood flow within your vessels.
Reasons to have a TCD
The most common reason your doctor may recommend you for a TCD is if you have had a stroke recently or are at risk for a stroke. It is important to measure blood flow from various arteries throughout the body, but especially the brain, as over 50% of strokes occur within deeper parts of the brain.
If you begin to show any of the symptoms below, your doctor may also recommend running a TCD:
- Blurred vision
- Chronic headaches or migraines
- Double vision
- Lack of coordination in limbs
- Ocular migraine
- Sudden loss of vision
Your doctor may also recommend this test if you have diabetes, hypertension, hypercholesterolemia, normal or low-tension glaucoma, and or certain cardiovascular conditions.
