Diagnostic Value of TI-RADS Stratification in Different Ages of Thyroid Nodule Patients / 天津医药

ABSTRACT

Objective To explore the applied value of thyroid imaging reporting and data system (TI-RADS) strati?fication in diagnosing thyroid nodules in patients with different ages.Methods A total of 527 patients with thyroid nod?ules (aged 26-65) were divided into four groupsaged 26-35 group, aged 36-45 group, aged 46-55 group and aged 56-65 group. TI-RADS was used to evaluate patients in four groups. The results of TI-RADS were compared with the pathologic di?agnostic analysis. Results For the low aged groups (aged 26-35 group and aged 36-45 group), the positive predictive val?ue, the negative predictive value and accuracy rate were more than 90%. With regard to the patients aged 46-55, the positive and negative predictive values and accuracy rate were 81.5%, 87.5%, and 81.9%, respectively. The positive and negative predictive values, accuracy rate were 76.6%,88.8%and 77.9%for patients aged 56-65 group. The diagnostic rate of TI-RADS in patients with thyroid lesions was lower in aged 56-65 group than that of other groups. Conclusion TI-RADS method is affected by age. The diagnostic rate is lower in the high age group than that of the low age group.
