A Salivary gland scan is a nuclear medicine test of the salivary glands. It shows salivary gland function. Typical effective dose 1 to 2 mSv, similar to about 4 to 8 months of natural background radiation (about 3 mSv a year).
General health information, not a diagnosis. In an emergency, call 102. Always consult a qualified health professional.
