Caption: Doppler ultrasound scan. A doctor uses ultrasound scanning to examine blood flow through the carotid arteries in a man's neck. He is watching the image on a monitor while holding a transducer on the patient's neck. Doppler ultrasound scanning is used to examine blood flow in different parts of the body. It enables doctors to detect turbulence in the flow of blood, which might reveal narrowing of blood vessels, clots or aneurysms (swellings). The small transducer emits ultra high frequency (inaudible) sound, which is reflected by blood vessels. The frequency of the echo reveals the rate of blood flow. This technique is harmless and causes no pain.
