Ultrasonically (US) guided fine-needle aspiration cytology was performed on 111 thyroid nodules and 4 swollen lymph nodes accompanied with thyroid disease. Thirty-four nodules were cytologically diagnosed as carcinoma.
Forty-five nodules were proved histologically. Accuracy of cytology was 84% and specificity was especially high(91%). Accuracy rate of echographic diagnosis for such small nodules was 69% and sensitivity was high (71%).
We consider that the combination of thyroid echography and fine-needle aspiration cytology is the most reliable method for diagnosis of small thyroid nodules.
