Panoramic sialography: an alternative technique.

Pantomographic sialography, referred to in this paper as panoramic sialography, was performed on 30 out of 51 patients. In 21 patients, it proved to be a good alternative technique to conventional sialography whilst in the other nine patients it was the principal method used to study the salivary glands. The techniques employed in this study for both conventional and panoramic methods are described. The radiation dose delivered to the patients was similar for both techniques. Water soluble contrast medium, Conray (325), was used in all cases.
