    Abstract
  •   Objective  Evaluate the reclassification of C-TI-RADS 4A thyroid nodules using S-Detect technology and strain elastography, and explore their diagnostic value for C-TI-RADS 4A thyroid nodules.  Methods  A total of 102 nodules were selected from 87 patients of C-TI-RADS 4A with clear-defined pathological results from April 2021 to April 2022 in the routine ultrasound examination of the First Affiliated Hospital of Nanjing Medical University. Samsung S-Detect technology and strain elastography were used to aid in the reclassification of nodules. The consistency between S-Detect technology, strain elastography, two methods to assist in manual reclassification diagnosis and pathological results was compared, as well as the diagnostic efficacy of the two methods for C-TI-RADS 4A type nodules.  Results  The diagnostic results of the two methods were consistent with the pathological results, the consistency between S-Detect technology and the pathological results (Kappa=0.652, P < 0.001) was higher than that of strain elastography (Kappa=0.381, P < 0.001), the consistency between the manual reclassification assisted by the two methods and the pathological results (Kappa=0.510, P < 0.001) was between the two methods. The sensitivity, specificity and accuracy of S-Detect technology and strain elastography for the benign and malignant diagnosis of C-TI-RADS 4A nodules were 93.10%, 70.45%, 83.33% and 62.07%, 77.27% and 68.63%, respectively. The sensitivity and accuracy of S-Detect technology in diagnosing C-TI-RADS 4A nodules was higher than that of strain elastography (all P < 0.05), however, the specificity of the two methods was not statistically significant (P > 0.05).  Conclusion  The S-Detect technique and strain elastography, as an assisted diagnostic method, have consistent diagnostic results of C-TI-RADS 4A type nodules with pathological results, and the S-Detect technique has high consistency.
