Abstract：Objective To investigate clinical application of nuclearmedicine imaging and Doppler ultrasound diagnosis in subacute thyroiditis.Methods A total of 133 patients with subacute thyroiditis and 133 patients without subacute thyroiditis treated in hospital from October 2011 to December 2013 were selected,who performed nuclear medicine imaging diagnosis and Doppler ultrasound diagnosis.The results of fine needle aspiration cytology were used as reference.The clinical diagnostic value(sensitivity,specificity,accuracy,positive predictive value)of nuclearmedicine imaging diagnostic examination,Doppler ultrasound diagnostic examination and combined diagnostic examination were analyzed.Results The sensitivity(80.5%),specificity(83.5%)and accuracy(82.0%)of nuclearmedical imaging diagnostic examination were higher than those of Doppler ultrasound diagnostic examination(69.2%,71.4%and 70.3%),the sensitivity(98.5%),specificity(97.7%)and accuracy(98.1%)of the combined diagnostic examination were all higher than those of nuclearmedical imaging diagnostic examination and Doppler ultrasound diagnostic examination,and the differences were statistically significant(P＜0.05).There was no statistically significant difference in the positive predictive value of Doppler ultrasound diagnostic examination,nuclearmedicine imaging diagnostic examination and combined diagnostic examination(P＞0.05).Conclusion Nuclearmedicine imaging diagnosis and Doppler ultrasound diagnosis are effectivemethods in diagnosis of subacute thyroiditis.Combined diagnosis can improve diagnostic rate of diseases.
