The test is performed in a hospital radiology department or in the health care provider's office by an x-ray technician. Patient may be given a sedative before the procedure.

Patient 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 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.

Patient 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

Patient should be asked a history of:

* Pregnant
* Allergic to x-ray contrast material or any iodine substance
* Allergic to any drugs

Patient must sign a consent form.Patient 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

What Abnormal Results Mean

Abnormal results may suggest:

* Narrowing of the salivary ducts
* Salivary gland infection or inflammation
* Salivary duct stones
* Salivary duct tumor


There is low radiation exposure. X-rays are monitored and regulated to provide the minimum amount of radiation exposure needed to produce the image. Most experts feel that the risk is low compared with the benefits. Pregnant women and children are more sensitive to the risks of x-rays.
