Sialogram
Alternative names:
ptyalography; sialography
How the test is performed:
The test is performed in a hospital radiology department or in the health care provider's office by an X-ray technician. You may be given a sedative before the procedure. You will be asked to lie on your back on the X-ray table. An X-ray is taken before the contrast material is injected to ensure that no stones are present to stop the contrast material from entering the ducts. A catheter (a small flexible tube) will be inserted through your mouth and into the duct of the salivary gland. A contrast medium in then injected into the duct so that the duct will show up on the X-ray. X-rays will be taken from a number of positions. You may be given lemon juice by mouth to help stimulate the production of saliva. Pictures are repeated to examine the drainage of the saliva into the mouth.
How to prepare for the test:
Inform the health care provider if you: You must sign a consent form. You will need to rinse your mouth with an antiseptic (germ-killing) solution before the procedure.

How the test will feel:
There is some discomfort or pressure when the contrast material is injected into the ducts. The contrast material may taste unpleasant.
Why the test is performed:
