[A comparison of digital luminescence radiography and conventional radiodiagnosis in sialography].
In 25 patients sialographies were obtained by both conventional film-screen system combinations and computed radiography (CR), the digital exposure dose being 50% of the conventional one. In CR two differently post processed images were obtained from one x-ray exposure: one "conventionally" processed image resembling a conventional film-screen system combination and a complementary "enhanced" image showing a higher edge enhancement at the same spatial resolution. CR proved to be equivalent to conventional radiography despite the reduction in exposure dose. Using high edge enhancement the peripheral glandular ducts as well as the central ducts superimposed by bony structures were optically accentuated. However, diagnostical information exceeding the conventional film-screen system combination was not obtained by CR. Artefacts by post processing procedures relevant for diagnosis were not observed.
