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.〔(【引用サイトリンク】url=http://www.nlm.nih.gov/medlineplus/ency/article/003812.htm )〕 The resulting diagram is called a sialogram. ==Indications== Indications include: * In the evaluation of the functional integrity of the salivary glands * In case of obstructions * To evaluate the ductal pattern * In case of facial swellings, to rule out salivary gland pathology * In case of intra-glandular neoplasms.
