For at least two hours before the test, you shouldn’t drink coffee or smoke, and you shouldn’t wear any jewelry or other items around your neck that might get in the way of the ultrasound waves. Also, you should wear clothes that are relaxed and make it easy for you to access your head and neck. Make sure to tell your doctor or nurse before the test if you are taking any medicines.
