摘要
目的:探讨弹性成像在甲状腺结节术前诊断中的价值。材料与方法:回顾性分析手术病理证实的84例157个甲状腺结节,比较二维超声、弹性成像诊断的敏感性、特异性。结果:弹性超声恶性结节敏感性90.0%,特异性96.9%,诊断一致率95.5%。二维超声恶性结节敏感性58.6%,特异性78.3%,诊断一致率75.2%。弹性成像结合二维超声敏感性96.6%,特异性98.4%,诊断一致率98.1%。敏感性和特异性均高于单独采用二维超声或弹性成像。三者比较有统计学意义(P<0.01)。结论:弹性成像结合二维超声有助于甲状腺结节术前良恶性区分。
Purpose： To explore the value of elastic imaging in the diagnosis of thyroid nodule. Materials and Methods： Retrospectively, 84 cases with 157 thyroid nodules which confirmed by surgical pathology were compared with two dimensional ultrasonic and elasticity imaging, focusing on the sensitivity and specificity. Results： The sensitivity of elastic uhrasonic for malignant nodules was 90. 0% , while specificity was 96. 9% , and the diagnostic agreement rate was 95.5%. The sensitivity of two dimensional ultrasonic for malignant nodules was 58. 6% , while specificity was 78.3% , and the diagnostic a- greement rate was 75.2%. The sensitivity of elasticity imaging combined with two-dimensional ultrasonic was 96. 6%, while the specificity was 98.4%, and the diagnostic agreement rate was 98. 1%. The sensitivity and specificity were higher than the sole use of two dimensional ultrasonic or elasticity imaging. All of them had statistical significance. Conclusion： It＇s helpful for the Elasticity imaging combined with two-dimensional ultrasound to the differential diagnosis of thyroid nodules.
