常规超声、超声弹性成像诊断甲状腺结节的价值

Diagnosis of Thyroid Nodules by Conventional Ultrasound and Ultrasound Elastography

目的观察对比常规超声成像与超声弹性成像诊断甲状腺结节良恶性的诊断价值。方法选取2017年1月—2018年1月我院收治的99例疑似甲状腺结节患者,在病理诊断前,所有患者均分别实施常规超声成像与超声弹性成像诊断检测,并以病理诊断结果为金标准,对比常规超声成像与超声弹性成像诊断效果。结果常规超声成像甲状腺结节诊符合率60.0%。超声弹性成像甲状腺结节诊断符合率95.3%。常规超声成像、超声弹性成像与金标准对比,差异具统计学意义(P<0.05)。常规超声成像敏感度68.0%,特异度58.3%;超声弹性成像敏感度97.6%,特异度87.5%,差异有统计学意义(P <0.05)。结论超声弹性成像诊断甲状腺结节良恶性效果高于常规超声诊断。

Objective To observe and compare the diagnostic effect of conventional ultrasound imaging and ultrasound elastography imaging in the diagnosis of benign and malignant thyroid nodules. Methods From January 2017 to January 2018, 99 patients with suspected thyroid nodules in our hospital were examined by conventional ultrasound imaging and ultrasonic elastography before pathological diagnosis. The results of pathological diagnosis were compared with those of conventional ultrasound imaging and ultrasonic elastography. Results The coincidence rate of routine ultrasonography in diagnosis of thyroid nodules was 60.0%. The diagnostic coincidence rate of ultrasound elastography for thyroid nodules was 95.3%. There were significant differences between conventional ultrasound imaging, ultrasound elastography and gold standard (P < 0.05). The sensitivity and specificity of conventional ultrasound imaging were 68.0% and 58.3% respectively. The sensitivity and specificity of ultrasound elastography were 97.6% and 87.5% respectively. Conclusion Ultrasound elastography is more effective than conventional ultrasound in the diagnosis of benign and malignant thyroid nodules.
