A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells . A regular ultrasound uses sound waves to produce images, but can’t show blood flow.
How long does it take to get results from a Doppler test?
It usually takes about 30 to 60 minutes . You can get results from a Doppler ultrasound very quickly. Sometimes, the person who runs the test is trained to do ultrasounds but isn’t a doctor.

It can show blocked or reduced flow of blood through narrow areas in the major arteries of the neck.
How do you check blood circulation in your legs?
A Doppler ultrasound uses sound waves to produce images that highlight blood flow in the leg arteries. This test detects and evaluates any blockages caused by plaque buildup.
Can Doppler ultrasound detect aneurysm?
With this technique, overall sensitivity for detection of aneurysms between 0.47 10 and 0.89 11 and specificity between 0.33 12 and 0.89 9 have been reported in relatively small studies, predominantly in patients with recent subarachnoid hemorrhage (SAH).
How much does Doppler ultrasound cost?
