[Computer scintigraphic investigations of function of large salivary glands].

Abstract

With the help of a gamma scintillation camera and a connected data manipulation system using the radioisotope 99mTc pertechnetate the large salivary glands of the head of 44 patients without pathological history of the salivary glands were examined by the results were interpreted. Because of the extended interval it was not able to ascertain normal values with clinical usefulness of the radionuclide accumulation in the large salivary glands. The time-activity-profiles which were won above "regions of interest" were very variably. The patients were divided classify and by using statistical test we found nonsecure influence of age or diabetes mellitus on the function of the salivary glands. Three types of normal time-activity-profiles were differed. In consequence of the discrepancy between the technical expance and the diagnostic value these method will to reserved to a limited range of indication outside the routine diagnostic.
