Abstract

We conduct research on diagnostic value of ultrasound guided fine needle aspiration (FNA) in the diagnosis of thyroid carcninoma compared with post-operative pathology at Hai Phong International Hospital.
Results: we had over 602 patients whose thyroid nodules had an FNA under ultrasound guidance and had cytology results graded according to Bethesda 2007, of which 99 patients underwent surgery. We found that FNA under ultrasound guidance is a simple method of high accuracy in the definitive diagnosis of thyroid cancer with a sensitivity 97.14%, specificity 93 , 1%, positive predictive value 97.14%, negative predictive value 93.1%, accuracy 95.96%. Bethesda's thyroid cytology is useful for classifying patients with thyroid nodules for prognosis, management, and treatment. The risk characteristics of ultrasound malignancy include:marked hypoechogenicity, irregular margins, taller-than-wider, and micro-calcification.
Conclusion: In our study, thyroid nodule FNA under ultrasound guidance is the most important first-line diagnostic methodin diagnosis of thyroid carcinoma.
