A Sialogram is a fluoroscopy test of the salivary ducts. It shows salivary duct stones or narrowing. Typical effective dose 0.1 to 0.5 mSv, similar to about 2 weeks to 2 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.
A Sialogram is a fluoroscopy test used to visualize the salivary ducts. It helps identify salivary duct stones or narrowing. The typical effective dose ranges from 0.1 to 0.5 mSv, equivalent to about 2 weeks to 2 months of natural background radiation. This test is often performed to diagnose recurrent salivary gland swelling. Preparation for the test depends on the specific study, and staff should inform patients if they are pregnant. The benefit of the test usually outweighs the small risk, and shielding or alternative methods can be considered. The Sialogram takes approximately 30 minutes to complete. General information about the test, not a diagnosis, should be interpreted by a qualified health professional.
