摘　　要：[目的]探讨超声检查对甲状腺良、恶性结节鉴别诊断的临床价值。[方法]对250例甲状腺结节患者术前行甲状腺彩色多普勒超声检查,并将超声钙化图像与术后病理诊断结果进行分析比较。[结果]恶性结节组的钙化率(67.60%)显著高于良性结节组,其血流信号检出率亦高于良性结节组。≤45岁组的患者恶性结节钙化率为88.46%,与>45岁组的患者相比,差异有统计学意义。超声诊断结果(以钙化率为判断良、恶性的指标)与病理诊断结果比较,差异无统计学意义。超声检查的敏感性为67.60%,特异性为83.24%。[结论]超声检查在判定甲状腺结节的良、恶性上具有较好的临床鉴别诊断价值。[Objective] To explore different ultrasonographic methods for benign and malignant thyroid nodules and their clinical significance in differential diagnosis. [Methods] A group of 250 patients with thyroid nodules were examined by Color Doppler ultrasonography before operation.And the ultrasonographic images of calcification and pathological results were compared. [Results] The calcification rate（67.60%） as well as the detection rate of blood flow in malignant group was significantly higher than those in benign group.In under-45-year-old patients,the calcification rate of the malignant thyroid nodules was 88.46%,the differences were statistically significant as compared with those in over 45-year-old patients.There was no significant difference found between the ultrasonographic diagnoses（according to the calcification rate） and the pathological results.The sensitivity of ultrasonography was 67.60%,and the specificity was 83.24%.[Conclusion] Ultrasonography is a good method to distinguish between malignant and benign thyroid nodules.
