What happens during a carotid ultrasound scan? icon plus
A sonographer will conduct the test using a small, hand-held device (transducer). This device emits sound waves and records the echo as the waves bounce off tissues, organs and blood cells.
A computer translates the sound waves into an image on a monitor in real-time. Your sonographer may use a Doppler ultrasound, which shows blood flowing through the arteries. A carotid ultrasound usually takes about 30 minutes. -
