Head and neck: Salivary gland: Warthin's Tumors
Note Warthin's tumor is the second most common benign salivary gland tumor, which is located almost exclusively in the parotid gland. Warthin's tumor accounts for about 15% of all epithelial tumors of the parotid gland. The initial description of the tumor goes back to Hildebrand in 1895, who considered this disease a variant of congenital epithelial cyst of the neck. In 1910, Albrecht and Arzt...
متن کاملQuantitative salivary gland scintigraphy.
OBJECTIVE Uptake of 99mTc-pertechnetate in salivary glands reflects intact salivary gland parenchyma. However, no standardized protocol for an accurate quantification of parenchymal function has been established so far. METHODS In this paper we report on a validated acquisition protocol supplying a normal database for standardized quantitative salivary gland scintigraphy. RESULTS The major ...
متن کاملQuantitative assessment of salivary gland function by radioisotopic scanning in a randomized trial of Pilocarpine for prevention of radiation induced Xerostomia [Persian]
Introduction: Radioisotope scanning is the best method for objective assessment of salivary gland function. Thus, it was used in a randomized trial of concomitant pilocarpine for assessment of radiation-induced xerostomia, in addition to subjective evaluation by an approved questionnaire and objective standard xerostomia grading. Methods: Patients randomized in placebo-controlled trial of...
متن کاملQuantification of Partial Volume Effects in Salivary Glands SPECT Images after Radiation Therapy of Head and Neck Tumors
Introduction: Radical radiation therapy of head and neck cancers may injure the salivary glands and reduce their function. Single-photon emission computed tomography (SPECT) images maybe used to evaluate function post-therapy. However, accurate quantification is hindered by the partial volume effects (PVEs). The present study involved the introduction of a PVEs quantif...
متن کاملPredicting Factors of Radiosensitivity in Individual Radiotherapy
BACKGROUND AND OBJECTIVE: Radiation dose in oncology protocols is different for each patient according to the type and grade of the tumor, as well as adjuvant therapies. In the current treatment regimens, some predicting factors of individual radiosensitivity have not been considered. Individual radiotherapy can lower side effects through radiation dose reduction with respect to tumor control. ...
