ABSTRACT

Objective:To assess the application of ultrasonography in the diagnosis of thyroid diseases with different types of nodules calcification.Methods:160 cases history of thyroid nodules with calcification confirmed by ultrasound diagnosis and pathological examination were performed the retrospective analysis. According to the ultrasonographic features of calcified nodules, it can be divided into type I, type II, type III and type IV, in which there are 210 benign nodules and 120 malignant nodules. Analyze the correlation between the different types of calcification and the benign or malignant thyroid nodules.Results: Type IV of thyroid benign nodules calcification is highest proportion, accounting for 46.7%(98/210), and significant difference (x2=76.27,P<0.05)compared with the other 3 types. Type I calcification in malignant nodules is highest proportion, accounting for 65%(78/120), and significant difference (x2=175.29;P< 0.05) compared with the other 3 types. In 108 cases of benign and malignant type I calcification, the incidence of malignant nodules is higher than benign nodules accounting for 72.2% (78/108), and type I calcium nodules were significantly different between those of benign and malignant (x2=42.67,P<0.05).Conclusions: Ultrasonography in the diagnosis of thyroid diseases with different types of nodules calcification had very important clinical application value. Type I calcified nodule has more important value in the diagnosis of thyroid carcinoma.
