Abstract：ObjectiveTo compare the diagnostic value of ultrasonography and fine needle aspiration in thyroid nodules.MethodsA total of 193 patients with thyroid nodules received ultrasound and fine needle aspiration were enrolled and retrospectively analyzed. The coincidence rate and application value of ultrasonography and fine needle aspiration in the diagnosis of thyroid nodules were evaluated.ResultsIn 193 cases of thyroid nodules, 97 cases (50.3%) were diagnosed of thyroid carcinoma and 96 cases (49.7%) of benign lesions based on the ultrasonography detection. However, 71 cases (36.8%) were diagnosed of thyroid carcinoma, 107 cases (55.4%) of benign lesions and 15 cases (7.8%) of suspicious cancer, according to the fine needle aspiration. Among the 97 cases with thyroid cancers diagnosed by ultrasonography, 63 cases (64.9%) were matched with fine needle aspiration, 22 cases (22.7%) were not met, and 12 cases (12.4%) were suspected. In 96 cases with benign lesions diagnosed by ultrasound, 85 cases (88.5%) were consistent with fine needle aspiration, 8 cases (8.3%) were not met, 3 cases (3.1%) were suspected, and the difference was significant (P=0.001).ConclusionBoth ultrasonography and fine needle aspiration are contributed to the diagnosis of thyroid nodules with a certain degree of compliance. However, ultrasound is better in the diagnosis of thyroid benign lesions than in thyroid cancer.
