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...

Background Congenital hypothyroidism (CH) may cause alterations in the child's global development. The current study aimed to screen the global development of children with and without congenital hypothyroidism, focusing on communication, and cognitive abilities and to ...

Purpose: To examine the relationships between degrees of Tc pertechnetate (TcO4 ) uptake after acid stimulation and the tumor size as well as histopathological subtypes of Warthin tumor and to evaluate the diagnostic accuracy of TcO4 − scintigraphy and routine magnetic resonance (MR) imaging in differentiating Warthin and non-Warthin tumors of the parotid gland. Methods: We reviewed a total of ...

A prospective trial was carried out to assess the contribution made by a radionuclide transverse-section view to conventional radionuclide scans of the brain. Each set of scans was reported by two independent teams of observers, but only one team viewed the tomography section. An abnormality rating was used to decide whether a set of scans was positive or normal. The reports for 512 patients we...

Background: Iodine-131 (I-131) is an effective treatment for differentiated thyroid carcinomas (DTC) after surgery. Salivary and lacrimal gland dysfunction has been described in patients receiving high doses of 1-131 due to radiation damage to salivary and lacrimal glands. Objective: This prospective study was conducted to determine the short term effect of oral 1-131 therapy administered to th...

Patterns of pertechnetate uptake were correlated with ultrastructural properties of the endothelial wall in 14 human brain tumours. In tumours with reduced uptake of the radionuclide, intercellular tight junctions were observed whereas absence of intercellular tight junctions was characteristic of all tumours with an increased uptake of pertechnetate. In some tumours with increased uptake, fene...

We characterized the scintigraphic and sonographic appearance of the thyroid gland in clinically normal horses to establish the value of these modalities for assessment of the thyroid gland in this species. Horses were divided into two age groups. One group consisted of eight horses between 3 and 10 years of age and the other of seven horses between 11 and 20 years of age. Total T4 concentratio...
