Abstract:
Sialolithiasis may be the most common disease of the salivary glands in patients more than 20 years of age. Approximately 19% of sialoliths occur in the parotid gland. Of these, only up to 71% can be successfully diagnosed radiographically. The remaining 29% provide a diagnostic dilemma. Xeroradiography, because of its tissue-edge enhancement, can distinguish tissue margins of different density more dramatically than can conventional imaging and is an invaluable aid in the diagnosis of nonradiopaque sialoliths.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
