Computed tomography of the parotid gland during contrast sialography.
By performing CT scanning during contrast sialography, tumors within the parotid gland can be shown and their configuration in relation to the remaining normal salivary gland and surrounding structures can be appreciated. This permits better evaluation of the relationship of the tumor to the facial nerve, possible extension of tumor beyond the gland, and benign versus malignant growth characteristics
