| 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(P<0.05)。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。 |

| Objective To evaluate the ultrasonographic characteristics of benign and malignant thyroid nodules, and the diagnostic value of elasticity imaging combined with conventional ultrasound. Methods A total of 280 thyroid nodules (240 patients) were performed conventional ultrasound and elasticity imaging respectively, and the characteristics of the diagnosis of each method were analyzed. All nodules were divided into benign and malignant according to their diagnostic criteria and the results were compared with the pathological findings. Results The sensitivity, specificity and accuracy of conventional ultrasound and elasticity imaging in diagnosis of benign and malignant thyroid nodules was 71.67% (43/60), 81.82% (180/220), 79.64% (223/280) and 85.00% (51/60), 88.18% (194/220), 87.50% (245/280), respectively, which was 91.67% (55/60), 98.18% (216/220) and 96.78% (271/280) in elasticity imaging combined with conventional ultrasound. Combining diagnostic value was higher than the pure elastic imaging and conventional ultrasound. Conclusion The performances of conventional ultrasound and elastography of benign and malignant thyroid nodules are characteristic, combined diagnosis has high efficiency in diagnosing benign and malignant thyroid nodules. |
