Sometimes bruits can be misleading, not heard when there is a blockage and heard when there is no or minor blockage. Doppler ultrasound is diagnostic, since it is normal i don't think you should worry. But at the same time you can cut down on your stroke risk by quitting smoking, regulating salt intake, limiting alcohol intake and daily exercise.Take care!
