  • Title: [Diagnosis of tumors of the parotid gland by sialography and saialoscintigraphy. A comparative study on 49 patients (author's transl)].
    Author: Magnus L, Schmitt G, Strötges MW, Lehmann G.
    Journal: Strahlentherapie; 1979 Mar; 155(3):171-4. PubMed ID: 432889.
    Abstract:
    169 patients with different diseases of the salivary glands were examined by means of sialography and sialoscintigraphy. The results of these examinations were analysed by a blindfold test. The sialographic diagnosis was correct for 47 of 49 tumors checked by histologic examinations. There is no specific criterium for the scintigraphic determiation of a tumor; there are concentrations as well as filling defects and retentions. The correct side, however, was found by scintigraphy in 46 cases. Only if a Warthin's tumor is suspected, the diagnosis can be confirmed by scintigraphy if a concentration is found. Generally, sialoscintigraphy should only be executed if sialography has technically failed. A distinction by means of sialography of benign and malignant tumors is not possible.
