目的比较超声弹性成像与常规超声诊断甲状腺良恶性结节的价值。方法选择自2015年1月至2015年8月在我科经病理学确诊的65例患者共97个甲状腺结节病灶为研究对象,其中良性结节64个,恶性结节33个。所有患者均接受常规超声和超声弹性成像检查,以病理结果为金标准进行比较。结果超声弹性发现,良性结节以1级和2级最为常见,分别占45.3%(29/64)和39.1%(25/64),而恶性结节以4级和5级最为常见,分别占48.5%(16/33)和45.5%(15/33)。常规超声诊断甲状腺结节的敏感性、特异性和准确度分别为42.4%(14/33)、81.3%(52/64)和68.0%(66/97);超声弹性成像诊断甲状腺结节的敏感性、特异性和准确度分别为94.0%(31/33)、96.9%(62/64)和95.9%(93/97);超声弹性成像诊断甲状腺结节的诊断甲状腺结节的敏感性、特异性和准确度均明显高于常规超声,差异有统计学意义(均P<0.05)。结论超声弹性成像能够明显提高诊断甲状腺结节的敏感性和特异性,值得在临床中推广应用。
Objective To compare the value of ultrasound elastography and routine ultrasound in the diagnosis of benign and malignant thyroid nodules. Methods From January 2015 to August 2015, a total of 97 thyroid nodules in 65 patients diagnosed by pathology in our department were studied, including 64 benign nodules and 33 malignant nodules. All patients underwent routine ultrasound and ultrasound elastography and pathological results were compared to the gold standard. Results Ultrasound elasticity found that benign nodules were the most common in grades 1 and 2, accounting for 45.3% (29/64) and 39.1% (25/64), respectively, while malignant nodules were most common in grades 4 and 5, accounting for 48.5% (16/33) and 45.5% (15/33). The sensitivity, specificity and accuracy of conventional sonography in the diagnosis of thyroid nodules were 42.4% (14/33), 81.3% (52/64) and 68.0% (66/97) respectively. Ultrasound elastography was sensitive to the diagnosis of thyroid nodules The specificity, specificity and accuracy were 94.0% (31/33), 96.9% (62/64) and 95.9% (93/97), respectively. The sensitivity and specificity of ultrasound elastography in the diagnosis of thyroid nodules Sexual and accuracy were significantly higher than conventional ultrasound, the difference was statistically significant (P <0.05). Conclusion Ultrasound elastography can significantly improve the sensitivity and specificity of diagnosis of thyroid nodules, which is worth popularizing in clinic.
