目的:评价超声甲状腺影像报告与数据系统及超声弹性成像对甲状腺微小癌的诊断价值,总结诊断经验。方法:2013年2月~2016年2月,医院甲状腺外科门诊检查住院的患者121例,采用超声诊断。结果:甲状腺微小87例,良性病变34例。联合诊断敏感性、特异性、阴性预测值、符合率高于弹性超声,联合诊断特异性、阳性预测值、阴性预测值、符合率高于数据系统,差异有统计学意义(P<0.05)。良性者与恶性者RI、结节纵横比差异无统计学意义(P>0.05),良性者PSV、应变率比值低于恶性者,差异有统计学意义(P<0.05)。结论:超声影像与数据报告系统、超声弹性成像联合应用诊断甲状腺微小癌的效果较好。
Objective: To evaluate the diagnostic value of ultrasound thyroid imaging report and data system and ultrasound elastography in the diagnosis of thyroid microcarcinoma, and to summarize the experience of diagnosis. Methods: From February 2013 to February 2016, 121 hospitalized patients undergoing thyroid surgery were examined by ultrasound. Results: Tiny thyroid 87 cases, benign lesions 34 cases. The sensitivity, specificity and negative predictive value of combined diagnosis were higher than those of elastic ultrasound, combined diagnostic specificity, positive predictive value and negative predictive value, and the coincidence rate was higher than that of data system (P <0.05). There was no significant difference in RI and nodule aspect ratio between benign and malignant patients (P> 0.05). The ratio of PSV and strain rate was lower in benign and malignant than in benign and malignant patients (P <0.05). Conclusion: Ultrasound imaging and data reporting system, ultrasound elastography combined with the diagnosis of thyroid microcarcinoma better.
