Sialogram
Sialogram or sialography is imaging of the salivary glands using x-ray[1]
Technique
A baseline radiograph of the required salivary gland would be taken , a cannula then is inserted in this salivary gland duct's opening in the mouth, a Radio-opaque fluid (Contrast medium) then is injected in the duct.
A series of radigraphs would then be taken to determine the flow of the fluid , identify any obstructions and its location , the rate of fluid excretion from the gland.
Usually the radiographs taken are lateral oplique views of the face [2]as Orthopantomogram's are not useful for the purpose of locating the area due to superimpositions and the way they are taken to put the teeth in the main field.
Indications
Contraindications
- Allergy to the contrast medium , mainly to Iodine.
- Acute salivary gland infections
