Abstract
In a 3-year period computed tomography (CT), both plain and in combination with sialography,
and conventional sialography were used in 59 patients who had or were suspected of
having salivary gland tumors, with special regard to attenuation in different tumors
and the tumor borders. The diagnostic information obtained with CT sialography and
conventional sialography was evaluated. The most valuable advantage of parotid CT
sialography is the possibility of demonstrating the tumor and its actual size and
relationship to the surrounding structures. The differentiation between benign and
malignant tumors must be based mainly on clinical investigation and fine-needle biopsy.
Conventional sialography may be an important complement to CT sialography because
of its ability to illustrate the morphology of the finest ducts.
