目的:分析钙化灶在超声诊断甲状腺癌中的意义。方法:分析244例超声检出甲状腺结节伴钙化患者的临床资料,分析钙化灶与甲状腺癌的相关性。结果:不同钙化形态(微钙化、粗钙化)中恶性率有显著性差异(2=70.984,P<0.01)。不同边界(边界清、边界不清)中恶性结节分布不同,(2=86.844,P<0.01);不同结节数目(单发结节、多发结节)中恶性钙化结节分布不同,(2=43.094,P<0.01)。结论:钙化灶在超声诊断甲状腺癌中具有重要价值。
Objective: To analyze the significance of calcification in the diagnosis of thyroid cancer by ultrasound. Methods: The clinical data of 244 patients with thyroid nodules and calcification were analyzed. The correlation between calcification and thyroid cancer was analyzed. Results: The malignant rates of different calcifications (microcalcification, calcification) were significantly different (2 = 70.984, P <0.01). The distribution of malignant nodules was different in different boundaries (clear boundary and unclear boundary) (2 = 86.844, P <0.01). The distribution of malignant calcified nodules in different nodules (single nodules and multiple nodules) (2 = 43.094, P <0.01). Conclusion: Calcification in the diagnosis of thyroid cancer by ultrasound is of great value.
