Response to letter to the editor

We would like to thank Dr. Sombat Muengtaweepongsa et al. for the interest in our article. We agree with the opinion that the contrasted Transcranial Doppler(TCD) is a safe procedure and the incidence of adverse effects is low. But we notice that in the letter, it was mentioned that up to 20% patients suffered from adverse transient neurological symptoms, such as headache, dizziness and visual aura after contrasted TCD and the number was beyond our expectation. So we are curious about the reference of this statement.
