What is it?
It is an ultrasound (high frequency sound wave) assessment of the carotid arteries that supply the circulation to the brain. It is combined with Doppler ultrasound and color Doppler to evaluate blood flow through these arteries.
Why is it done?
It is used to assess the structure and flow velocities of blood across the carotid arteries, and this helps to determine the risk for stroke and TIAs (mini stroke).
How is it done?
The patient lays down on the exam table and the sonographer will use a wand (probe) on the skin of either side of the neck. A gel will be used with the wand to enable good imaging.
The sonographer will perform the test and the results will be interpreted by the physician, which will be discussed at the next follow up appointment.
