Ultrasound features of thyroid cancer
Main Article Content
Abstract
SUMMARY
Purpose: To find features of thyroid malignancy nodule on the ultrasound.
Material and Methods: A total 307 thyroid nodules of 272 patients (146 malignant nodules on the 146 patients, 161 benign nodules on the 126 patients), who underwent thyroid ultrasound examintation. There ultrasound features are compared with
pathologic result for evaluation value.
Result: The following US features showed a significant association with malignancy: solid component, hypoechogenicity (Sensitivity 80.82%; Specificity 59.01%), marked hypoechogenicity (Sensitivity 16.44%, Specificity 98.76%), irregular margins
(Sensitivity 77.4%, Specificity 92.55%), microcalcifi cations (Sensitivity 69.18%, Specificity 97.52%), and taller-than-wide
shape (Sensitivity 69,86%, Specificity 94.41%).
Conclusion: High-resolution thyroid US is the most useful diagnostic tool for evaluating thyroid nodules. Ultrasound features of thyroid nodules malignancy include a hypoechonic, mark hypoechonic, taller than wide, irregular margins and microcalcification.
