Abstract:
ObjectiveTo study the value of quantitive scoring methodby ultrasound in differential diagnosis of thyroid nodule.MethodsTotally 1 360 patients with thyroid carcinoma or nodular goiter were given preoperative ultrasound examination of thyroid. The features of thyroid nodule and their signiifcances in diagnosing thyroid carcinoma were evaluated by logistic regression analysis. Surgical pathology was taken as golden standard. Signiifcant feature was scored as 1 point, and insigniifcant feature was scored as 0 point. In two groups, the data were analyzed statistically.ResultsLow echo, obscure boundary, incomplete or no capsule, incomplete or no halo, aspect ratio≥1, internal lfow, posterior acoustic attenuation, no cystic echo, microcalciifcation and background Hashimoto′s thyroiditis showed correlation with malignancy. There were statistically significant difference between thyroid cancer and nodular goiter in thyroid nodules scores (χ2=802.08,P<0.05). Of 768 thyroid nodules with<6 points, 742 were benign and 24 were malignant. Of 60 thyroid nodules≥10 points, 2 were benign and 58 were malignant. Of 314 thyroid nodules with 8-9 points, 60 were benign and 254 were malignant. Of 368 thyroid nodules with 6-7 points, 155 benign and 213 were malignant.ConclusionsQuantitive scoring of thyroid nodule had clinic signiifcance in differential diagnosis. Thyroid nodule with>8 points accounted for the majority of malignancy and should be considered for surgery.
