Sialography is a radiographic examination of the salivary glands that involves injecting contrast medium into the salivary duct followed by x-ray imaging. It is used to identify calculi, masses, inflammation or other abnormalities of the parotid or submandibular glands. The procedure involves dilating the duct opening, inserting a catheter, and taking x-ray images as contrast is injected to outline the ductal system. Findings are evaluated for any obstructions, strictures, or other pathology. Potential complications include sialadenitis or duct damage.

CT is one of the frequently used diagnostic imaging modalities in Radiology. Knowledge about image quality and artifacts is essential when diagnosing a patient with the help of CT images. Moreover, Radiology Technologist's should be very well aware about the ways to identify and eliminate or minimize the artifacts in CT for better image quality.

• Sialography 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.
• This is the study to demonstrate the parotid or
submandibular glands by injection of contrast
medium into the duct system.

cranial tube tilt.
• Positioning for submandibular gland
• Lateral view is taken with 15-20 degrees
cranial tube tilt.
