Application of xeroradiography in sialography.

Sialography was carried out in healthy volunteers and in patients with Sjögren's syndrome. A comparison was made between xeroradiography and conventional radiography. Superior images were obtained with xeroradiography and this technique also tended to reveal glandular structure which was obscured by overlying bone when using conventional radiography. In addition to this, there was considerably greater latitude in exposure and the skin dose of radiation using xeroradiography was slightly less.
