[Optimization of the radiographic technic in parotid sialography. Experimental findings and clinical evaluation of the selection of the film-screen combination].
A suitable choice of film-screen combination is certainly the essential condition for achieving diagnostically reliable results together with the benefit of a low dosage for the patient. In parotid sialography, the choice of one particular film-screen combination depends on the different thickness of various glandular areas and on the particular anatomical site of the gland which inevitably causes the superimposition of the thinnest canalicular ducts with the adjacent areas. We have therefore performed an experimental-clinical study in order to evaluate the combination which can guarantee the most elevated diagnostic increase. The analysis of the results shows useful indication as far as the use of mammographic systems is concerned. These allow more diagnostic information together with a sufficiently low dosage for the patient.
