| 目的 评价常规超声成像与超声弹性成像在诊断甲状腺结节良恶性中的价值。方法 2013年6月—2015年6月,该院对80例甲状腺结节患者,于结节切除术前进行常规超声及超声弹性成像检查。并以病理诊断为对照,评估常规超声成像及超声弹性成像对甲状腺结节良恶性的诊断价值。结果 术后组织标本经病理诊断共106个甲状腺结节,其中79个良性结节,27个恶性结节。常规超声检查准确诊断甲状腺结节72个,其中良性结节有55个,恶性结节有17个；超声弹性成像检查准确诊断甲状腺结节102个,其中良性结节有74个,恶性结节有28个。常规超声检查对甲状腺结节良恶性诊断的灵敏度、特异度、阳性预测值、阴性预测值及诊断准确率分别为62.96%、69.62%、41.46%、84.61%、67.92%,明显低于超声弹性成像检查的92.59%、91.14%、78.13%、97.30%、96.22%(均P＜0.05)。结论 与常规超声成像检查比较,超声弹性成像检查对甲状腺结节的诊断率高,且超声弹性成像能更准确诊断甲状腺结节良恶性状态。 |

| Objective To evaluate the values of ultrasound elastography and conventional ultrasonography in diagnosing the thyroid nodule malignancy. Methods Eighty thyroid nodule patients who receiving medical examination in our hospital from June 2013 to June 2015 were selected.Ultrasound elastography and conventional ultrasonograph were utilized for the evaluation of thyroid nodules before operation,and the values of which in diagnosing the thyroid nodule malignancy were evaluated with pathological diagnosis results as standard. Results After postoperative pathological verification,the 106 thyroid nodules were differentiated into 79 benign nodules and 27 malignant nodules.Seventy-two thyroid nodules were accurate diagnosis by conventional ultrasonography with 55 benign nodules and 17 malignant nodules.One hundred and two thyroid nodules were accurate diagnosis by ultrasound elastography with 74 benign nodules and 28 malignant nodules.The sensitivity (62.96%),specificity (69.62%),positive predicted value (41.46%),negative predicted value (84.61%) and diagnosis accuracy (67.92%) of conventional ultrasonography for the diagnosis of malignant nodules were significantly lower than those of ultrasound elastography (92.59%,91.14%,78.13%,97.30%,and 96.22%,respectively),and the difference was of statistical significance (with P＜0.05). Conclusions Compared with conventional ultrasonography,ultrasound elastography can discover more thyroid nodules,and the accuracy of ultrasound elastography in the evaluation of thyroid nodules is higher. |
