【摘要】：目的探讨甲状腺良恶性结节的声像图诊断特点,及弹性成像联合常规超声诊断的价值。方法分别对240例患者的280个甲状腺结节行常规超声和弹性成像检查,分析其超声特点。根据各诊断标准将所有结节进行良恶性归类,并与病理结果比较。结果常规超声、弹性成像鉴别甲状腺结节良恶性的敏感度、特异度、准确率分别为71.67%(43/60)、81.82%(180/220)、79.64%(223/280),85.00%(51/60)、88.18%(194/220)、87.50%(245/280)。弹性成像联合常规超声鉴别甲状腺结节良恶性的敏感度、特异度及准确率分别为91.67%(55/60)、98.18%(216/220)及96.78%(271/280),其诊断价值高于单纯弹性成像和常规超声检查(P0.05)。结论甲状腺良恶性结节的常规超声、弹性成像表现较具特征性,联合诊断对鉴别甲状腺结节良恶性有较高的效能。
[Abstract]:Objective to investigate the diagnostic features of benign and malignant thyroid nodules by ultrasonography and the value of elastic imaging combined with conventional ultrasonography. Methods 280 thyroid nodules were examined by conventional ultrasonography and elastic imaging respectively. According to the diagnostic criteria, all nodules were classified as benign and malignant, and compared with pathological results. Results the sensitivity, specificity and accuracy of conventional ultrasonography and elastography in differentiating benign and malignant thyroid nodules were 71.67% (43 / 60), 81.82% (180 / 220), 79.64% (223 / 280), 85.00% (51 / 60) and 88.18% (194 / 220), respectively. The sensitivity, specificity and accuracy of elastic imaging combined with conventional ultrasound in differentiating benign and malignant thyroid nodules were 91.67% (55 / 60) and 98.18% (21.6 / 220) and 96.78% (271 / 280), respectively. Conclusion conventional ultrasonography and elastography are characteristic of benign and malignant thyroid nodules. Combined diagnosis is effective in differentiating benign and malignant thyroid nodules.
