PURPOSE
To evaluate the diagnostic value of shear wave elastography (SWE) combined with contrast-enhanced ultrasonography (CEUS) in diagnosing thyroid imaging reporting and data system (TI-RADS) category 4a and 4b nodules.
METHODS
TI-RADS, SWE, and CEUS features of 71 thyroid nodules (23 benign, 48 malignant) confirmed by postoperative pathological results were retrospectively analyzed. The diagnostic efficiency of each single method and that of a combination of three methods were compared.
RESULTS
The sensitivity and specificity in diagnosing thyroid nodules were 70.83% and 65.22% for TI-RADS, 68.75% and 91.30% for SWE, 77.08% and 78.26% for CEUS, and 91.67% and 95.65% for TI-RADS + SWE + CEUS, respectively. The area under the curve for TI-RADS, SWE, CEUS, and TI-RADS + SWE + CEUS in diagnosing thyroid nodules were 0.680, 0.839, 0.799, and 0.937, respectively. A significant difference was observed between a combination of the three methods and any of them alone (p < 0.05).
CONCLUSION
Combining SWE and CEUS improves the differential diagnosis of TI-RADS category 4a and 4b nodules.
目的
评估剪切波弹性成像（SWE）联合超声造影（CEUS）在诊断甲状腺影像报告和数据系统（TI-RADS）4a类和4b类结节中的诊断价值。
方法
回顾性分析71个经术后病理结果证实的甲状腺结节（23个良性，48个恶性）的TI-RADS、SWE和CEUS特征。比较每种单一方法以及三种方法联合使用的诊断效率。
结果
TI-RADS诊断甲状腺结节的敏感性和特异性分别为70.83%和65.22%，SWE为68.75%和91.30%，CEUS为77.08%和78.26%，TI-RADS + SWE + CEUS为91.67%和95.65%。TI-RADS、SWE、CEUS以及TI-RADS + SWE + CEUS诊断甲状腺结节的曲线下面积分别为0.680、0.839、0.799和0.937。三种方法联合使用与任何一种单独方法之间存在显著差异（p < 0.05）。
结论
SWE和CEUS联合使用可提高TI-RADS 4a类和4b类结节的鉴别诊断能力。
