What are normal results of a Doppler ultrasonography?
A Doppler ultrasonography test showing no restricted blood flow is a normal finding.
What precautions need to be taken when using transcranial Doppler ultrasonography?
Ultrasonography procedures are safe, noninvasive, and painless. No special precautions are necessary.
Why is Doppler Ultrasonography widely used?
The test is widely used because it is noninvasive, uses no x rays, and gives excellent images. It is harmless, painless, and widely available.

What care should a patient receive after a transcranial Doppler ultrasonography?
The gel is washed off with soap and water. No other after care is needed.
What is Doppler ultrasonography?
direct measurement of blood flow and rates of flow, sometimes performed in conjunction with stress testing (exercise between tests).
What is the imaging study uses sound waves to detect blood flow in the carotid and intracranial arteries?
doppler ultrasound
