A carotid ultrasound is a diagnostic procedure that uses sound waves to look inside your carotid arteries, which supply blood to your brain.
A carotid ultrasound is performed to determine if there is a narrowing or blockage within the carotid artery which increases the risk for stroke.
You should wear loose and comfortable clothes and remove clothing or jewelry from the area to be examined. No other preparation is generally required unless specified by your doctor.
A small amount of gel is applied on the skin surface. A handheld device called a transducer that sends and receives sound waves is pressed against the skin of your neck. Sound waves are generated that bounce off the body tissues including the arteries and images are created on a monitor based on the frequency and amplitude of the returning soundwaves.
After the procedure is completed, the ultrasound gel can be wiped off your skin and you can return to routine activities almost immediately.
