Diagnostic value of FNA, ultrasound elastography and CEUS in thyroid carcinoma.

BACKGROUND

To investigate the role of fine needle aspiration cytology (FNA), sonoelastography and contrast-enhanced ultrasound (CEUS) in the diagnosis of thyroid carcinoma.

METHODOLOGY

A total of 150 patients with suspected thyroid cancer admitted to our hospital from January 2019 to December 2021 were selected and divided into group A, group B and group C according to random number table, with 50 cases in each group. FNA was used in group A, ultrasound elastography was used in group B, and CEUS was used in group C. Pathological diagnosis was performed in all patients, and the diagnostic sensitivity, specificity, and accuracy were compared among the three groups.

RESULTS

The diagnostic sensitivity, specificity and accuracy of FNA in group A were 90.91%, 70.59% and 84.00%, respectively; the diagnostic sensitivity, specificity and accuracy of ultrasound elastography in group B were 94.12%, 81.25% and 90.00%, respectively; the diagnostic sensitivity, specificity and accuracy of CEUS in group C were 88.57%, 73.33% and 84.00%, respectively; the three groups were compared (P > 0.05).

CONCLUSION

All three diagnostic techniques had a relatively high sensitivity and accuracy in the diagnosis of thyroid carcinoma. Ultrasound elastography had the highest sensitivity and specificity among the three techniques, while FNA and CEUS had similar diagnostic performance.
