Final answer:
The radiographic examination of the salivary glands using contrast medium is called sialography. Sialography involves injecting a contrast medium into the salivary gland ducts to evaluate the structure and function of the salivary glands. It helps identify the underlying cause of symptoms and guide treatment.
Step-by-step explanation:
The radiographic examination of the salivary glands using contrast medium is called sialography.
Saliva is produced by the three major pairs of salivary glands: the parotid glands, the sublingual glands, and the submandibular glands. Sialography is a diagnostic procedure that involves injecting a contrast medium into the salivary gland ducts to evaluate the structure and function of the salivary glands.
For example, if a patient is experiencing difficulty swallowing or has a blocked salivary gland, sialography can help identify the underlying cause and guide treatment.
