Abstract:
Objective To evaluate the value of elastic strain ratio (SR) in ultrasound guided fine needle aspiration (US-FNA) of thyroid nodule.Methods A total of 222 thyroid nodules from 216 patients were reviewed and analyzed by Logistic regression of clinical data,2D ultrasound,and SR.The odds ratios of variables in the equation were compared to assess various variables,especially of SR in the diagnosis.The sensitivity,specificity,and accuracy of the SR method,US-FNA method,and combined method were calculated.Results Three statistically significant features finally entered the Logistic regression model,followed by SR,echo,and age according to the odds ratio.The sensitivity,specificity,and accuracy of the SR method,US-FNA method and combined method were 85.4％,82.1％,83.3％ ; 91.5％,82.1％,85.6％ ; 97.6％,94.3％,95.5％ respectively.Conclusions SR＜0.5 is the most important risk factor in differential diagnosis of thyroid malignant nodules from benign nodules.SR raises the sensitivity,specificity,and accuracy of US-FNA method and plays an important role in diagnosing thyroid nodules via US-FNA.
