Other imaging modalities are often used now to assess the Salivary Glands – Ultrasound or MRI. Your referral form will be assessed by our specialist radiologist and the best imaging technique/modality selected for your clinical indications.
Why a Sialogram?
Swelling and pain in your salivary glands can be caused by a blockage from a calculus or stone in the salivary duct. A Sialogram is performed to locate the blockage and diagnose what is causing it.
There is a consent form for this examination outlining the preparation, procedure, possible complications and aftercare. You will be asked to read through this, asked questions to ensure you are happy to continue with the procedure and lastly to sign the consent form.
Plain x-rays are performed first to see if the calculus can be seen on x-ray.
The radiologist will then squirt some bitter liquid (like lemon juice) into your mouth to activate the salivary glands. A very small tube is inserted into the salivary duct and some contrast media is injected to show the salivary glands. This causes slight discomfort due to gland fullness, but should not be painful. X-rays are then taken.
The contrast will spill back into your mouth with help from the lemon juice again, and you can go home. The contrast can be swallowed.
A detailed aftercare sheet will be given following this procedure, outlining any possible complications.
After the examination
The radiologist will review the pictures and provide a written report to your referring doctor.
Please settle your account on the day of the examination.
