Sialogram
定义
唾液谱是一种
The salivary glands are located on each side of the head, in the cheeks just in front of the ears, and under the jaw. They release saliva into the mouth.
选择的名字
Ptyalography; Sialography
How the Test is Performed
The test is performed in a hospital radiology department or a radiology facility. The test is done by an x射线 technician. A radiologist interprets the results. You may be given a medicine to make you calm before the procedure.
You will be asked to lie on your back on the x射线 table. An x射线 is taken before the contrast material is injected to check for blockages that might prevent the contrast material from entering the ducts.
A catheter (a small flexible tube) is inserted through your mouth and into the duct of the salivary gland. A special dye (contrast medium) is then injected into the duct. This allows the duct to show up on the x射线. X-rays will be taken from several positions. The sialogram may be performed along with a CT scan.
You may be given lemon juice to help you produce saliva. The x射线s are then repeated to examine the drainage of the saliva into the mouth.
How to Prepare for the Test
Tell the health care provider if you are:
- 怀孕了
- Allergic to x射线 contrast material or any iodine substance
Allergic to any drugs
You must sign a consent form. You will need to rinse your mouth with germ-killing (antiseptic) solution before the procedure.
How the Test will Feel
You may feel some discomfort or pressure when the contrast material is injected into the ducts. The contrast material may taste unpleasant.
Why the Test is Performed
A sialogram may be done when your provider thinks you might have a disorder of the salivary ducts or glands.
What Abnormal Results Mean
Abnormal results may suggest:
- Narrowing of the salivary ducts
Salivary gland infection 或炎症Salivary duct stones Salivary duct tumor
风险
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 potential benefits. 怀孕了 women should not undergo this test. Alternatives include tests like an MRI scan that do not involve x射线s.
