St Vincent's Clinic Medical Imaging & Nuclear Medicine

Salivary Scan

A Salivary Scan evaluates obstruction, function and malignancy of the salivary glands.

What will happen when you have your Salivary Scan

When you arrive in the Nuclear Medicine department you will be given a small injection of a radioactive tracer into a vein in your arm. This injection is not known to have any side effects. 15 minutes after the injection images will be obtained of your head and neck for approximately 45 minutes. After these images are obtained you will be asked to drink a cup of water mixed with a small amount of lemon juice. Once you have finished drinking the water and lemon juice more images of your head and neck will be obtained and this should take 30 minutes.
