Doppler ultrasound uses harmless sound waves to create a picture of your blood flow. This test can detect narrow or blocked arteries and blood clots in the veins.
|You may feel pressure during the test. You may also hear a "whooshing" noise, which is the sound of your blood flowing.
Before your test
The test takes 30 to 60 minutes. Allow time to check in. When you arrive, you may be asked to undress from the waist down or to change into a gown.
Tell the sonographer
Tell your sonographer if:
During your test

If the test is done on your neck
You will lie on an exam table.
Your head will be turned to the side.
Nongreasy gel will be applied to your neck.
The sonographer will then press a hand-held transducer (probe) against your neck.
If the test is done on your leg or arm
Although the sonographer can answer questions about the test, only a doctor can explain the results.
Your test results
