Salivary Gland Scintigraphy in Patients with Sjogren’s Syndrome: A local Experience with Dual-tracer
Objective(s): To review the findings of the patients with Sjögren’s syndrome (SS) having technetium-99m-pertechnetate (99mTc-pertechnetate) and gallium-67 citrate (Ga-67) salivary gland scintigraphy in the past eight years.Methods: The patients with SS, who were referred to our department for salivary gland scintigraphy during January 2008-December 2015 were studied using both 99mTc-pertechneta...

Salivary gland involvement is one of the radioiodine therapy complications. Salivary gland scintigraphy in quantitative mode can accurately evaluate salivary gland function. Methods: Salivary gland scintigraphy was performed with Tc-99m Pertechnetate, at the time of iodine therapy as a basic study and then 3 weeks and 3 months afterwards. Ejection Fraction (EF) of parotid and submandibula...
