摘要
目的探讨超声弹性成像在甲状腺良恶性结节中的诊断价值。方法选取2012年12月至2014年4月住院治疗的甲状腺结节患者108例（143个结节）,行超声弹性成像检查,分别采用超声弹性评分法和应变率比值法判断结节良恶性,数据分析采用SPSS19.0软件,以病理诊断为金标准,对两种方法诊断的灵敏度、特异性、准确性进行χ~2检验,以P〈0.05表示差异具有统计学意义。结果病理诊断显示,良性104个,恶性39个。94.87%恶性结节为甲状腺乳状癌,70.19%良性结节为结节状甲状腺肿;超声弹性评分法诊断甲状腺恶性肿瘤的灵敏度、特异性和准确率分别为92.31%（36/39）、81.73%（85/104）和84.62%（121/143）;应变率比值法诊断甲状腺恶性肿瘤的灵敏度、特异性和准确率分别为89.74%（35/39）、84.62%（88/104）和86.01%（123/143）;两种方法比较差异无统计学意义（P〉0.05）。结论超声弹性成像运用超声弹性评分法和应变率比值法在甲状腺良恶性结节鉴别诊断中有较好的价值,能帮助医生鉴别结节的性质,值得在临床推广。
Objective To assess the diagnostic value of ultrasound elasticity imaging on benign and malignant thyroid nodules. Methods From December2012 to April 2014,108 patients with thyroid nodules（ 143 nodules） were treated in our hospital by using ultrasound elasticity imaging. The ultrasound elasticity score and strain ratio in judging benign or malignant nodules were confirmed by pathological examination. Data analysis was performed by using SPSS19. 0 software. The diagnostic sensitivity,specificity and accuracy of the two methods were compared by using the Chi-square test. A P value 0. 05 was considered statistically significant. Results Pathological diagnosis showed 104 benign and 39 malignant nodules. Of the malignant nodules,94. 87% were thyroid emulsion carcinomas,whereas 70. 19% were benign nodules similar to nodular goiters. The sensitivity,specificity and accuracy of ultrasound elasticity in the diagnosis of thyroid malignancies were 92. 31%（ 36 /39）,81. 73%（ 85 /104） and 84. 62%（ 121 /143）respectively. The sensitivity,specificity and accuracy of strain ratio in the diagnosis of thyroid malignancies were 89. 74%（ 35 /39）,84. 62%（ 88 /104） and 86. 01%（ 123 /143） respectively. The diagnostic sensitivity,specificity and accuracy of ultrasound elasticity and strain ratio were not statistically significant（ P〉0. 05）. Conclusion Ultrasound elastography using ultrasound elasticity and strain ratio in the differential diagnosis of benign and malignant thyroid nodules is helpful to identify the nature of nodules,and it is feasible in clinical practice.
