What is a sialogram test?
A sialogram is an x-ray procedure that looks at the salivary ducts and glands. A small tube is inserted into the gland. Contrast (an x-ray dye) is then injected into the salivary glands, which allows them to be seen more clearly on the x-ray pictures. The dye will show on the x-ray if there are any issues with the saliva glands
