Salivagram — WR Pediatric Imaging Procedure
What is a salivagram?
A salivagram is a diagnostic imaging procedure that outlines the flow of a mixture of saliva and a radiopharmaceutical from the mouth through the esophagus and the stomach. In aspiration, the radiopharmaceutical can be visualized as it flows into the lungs.
Why would my doctor request a salivagram?
A salivagram can help assess:
- Aspiration of saliva into the lungs
How is a salivagram performed?
You will be greeted by one of our technologists who will explain to you/your child what will happen during the examination. Imaging will begin and a tiny drop of a radiopharmaceutical called Technetium-99m Sulfur Colloid will be placed on your child’s tongue and allowed to mix with saliva. The radiopharmaceutical is harmless, tasteless, and odorless. Imaging will take one hour. It is important that your child remain as still as possible to obtain the best quality images.
How to prepare for a salivagram
There is no preparation needed for this test. Your child may bring a security blanket/toy with his/her to hold during the procedure.
What can be expected during the procedure?
Although the camera may appear large and intimidating, it does not touch your child.
What happens after the study?
Once the study is complete, it will be evaluated for quality. If there was too much motion, the study may need to be repeated. If there was no motion, your child will be free to leave and resume normal activity.
