Sialography is the imaging of the salivary glands, most commonly the parotid gland. In most cases, ultrasound with sialography, if required is an appropriate imaging modality for the investigation of ductal pathology.

In cases of sialolithiasis , ultrasound of the parotid glands is a useful, readily available, noninvasive, and inexpensive option.

The procedure is essentially the same as a conventional sialogram, after which the patient is positioned in a CT in a neutral supine position. Multiplanar data acquisition allows for 3D reconstruction. Intravenous contrast material can be administered for better soft tissue evaluation, especially for parotid masses. In the s and s, when this technique was first introduced, slower CT scans called for delayed ductal emptying, for which atropine was given.

MRI sialography is a fairly sensitive and reliable method of evaluating the salivary glands. Fast acquisition heavily T2 weighted sequences e. MR contrast administered intravenously is a useful adjunct. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Updating… Please wait.

Sialography also termed radiosialography is the radiographic examination of the salivary glands. It usually involves the injection of a small amount of contrast medium into the salivary duct of a single gland, followed by routine X-ray projections. Contrast agents are classified into two groups: fat-soluble contrast agents and water-soluble contrast agents. Water-soluble contrast agents can fill the finer elements of the ductal system. Fat-soluble contrast agents are viscous and can cause allergic reactions.
