目的观察超声弹性成像联合CT对甲状腺结节良恶性的鉴别诊断。方法选取医院收治的甲状腺结节患者70例(共98个甲状腺结节)为研究对象,对所有患者行常规CT检查及超声弹性成像检查,观察并对患者常规的恶性甲状腺结节与良性甲状腺结节CT检查边界清晰率及超声弹性成像表现。结果恶性甲状腺结节组清晰率为10.52%,低于良性甲状腺结节组的75.95%,差异有统计学意义(P<0.01)。超声弹性成像通过硬度分级对甲状腺结节进行诊断,可提高诊断的准确率。结论超声弹性成像联合CT对甲状腺结节良恶性能作出及时且有效的诊断,是一种安全、准确率高的检查方法,值得临床推广应用。
Objective To observe the differential diagnosis between benign and malignant thyroid nodules by ultrasound elastography and CT. Methods Seventy patients with thyroid nodules (98 thyroid nodules) admitted to the hospital were enrolled in this study. All patients underwent routine CT and ultrasound elastography. The incidence of malignant thyroid nodules and benign thyroid nodules CT scan border clear rate and ultrasound elastography performance. Results The clear rate of malignant thyroid nodules was 10.52%, which was lower than that of benign thyroid nodules (75.95%) (P <0.01). Ultrasound elastography through the hardness classification of thyroid nodules for diagnosis, can improve the diagnostic accuracy. Conclusion Ultrasound elastography combined with CT to make a timely and effective diagnosis of benign and malignant thyroid nodules is a safe and accurate method of examination, worthy of clinical application.
