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.
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:
You’ve had a stroke
You’ve had symptoms, such as short-term loss of strength, speech, or vision
During your test
The ultrasound may be done on your neck, leg or arm, depending on the area of your problem.
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
Nongreasy gel will be applied to the skin over the area to be examined.
The probe will be pressed against the skin over the gel.
Although the sonographer can answer questions about the test, only a doctor can explain the results.
Your test results
Before leaving, you may need to wait briefly while your images are being reviewed. Your doctor will discuss the test results with you during a follow-up appointment or over the phone.
