【Abstract】 Objective To evaluate the changes in salivary gland function before and after radioiodine remnantablation（RRA）treatment inpatients with differentiated thyroidcancer（DTC）who have undergone thy-roidectomy.MethodsToensurecomparisonofsali-vary gland function under the same thyroid functional status，we retrospectivelyselected patients who had under-gone two radioiodine（RAI） treatments as subjects.All patients received RAI treatment dose of 3.7GBq.Salivary gland function was quantitatively analyzed through scintigraphy before and afterRRA treatment （oneweek before treat-ment，and6＼～27monthspost-treatment，withanaverage in-terval of 11.68 months）.Salivary gland imaging examinations were conducted before each RAItreat-ment （TSH>30 mU/L）. ResultsThe uptake indexof the right parotid gland before and after RRA treatment was 4.2and3.6，re-spectively， andfortheleftparotid gland，itwas3.8and3.9;fortherightsubmandibulargland，itwas 4.2and4.2，andforthe left submandibular gland，it was3.9and 3.9.The excretion fraction for theright parotid gland was 46% and 49 % and for theleft parotid gland，it was 48% and 48% ; for the right submandibular gland，it was 36% and 37% ，and for the left submandibular gland， it was 33% and 34% .Statistical analysis showed that neither the uptake index nor the excretionfractionof theparotidorsubmandibularglandsreachedstatisticalsignificancebe-foreandafterRRAtreatment （ P >0.05）.ConclusionThe most commonly used therapeutic dose of 3.7 GBq for RRA does not significantly affect salivary gland function.
