We performed an experimental study for“sonographic sialography", sonography after injecting sonographic contrast medium through ducts. Sonazoid was acceptable in manipulation capability and osmotic pressure, and caused no inflammatory reaction to rat parotid glands. We could obtain enough signals of contrast medium in our phantom experiments. Supposed problems when it is applied in a clinical setting are difficulty in measuring duct diameter by enhancing effect, and inferior depiction of deeper parts when the imposed parts above are enhanced.
