【摘要】：目的探讨CEUS对甲状腺TI-RADS 3、4级结节的诊断价值。方法回顾性分析95例常规超声诊断为TIRADS 3、4级的甲状腺结节(共95个结节,均经手术病理证实)的CEUS表现,分析CEUS对甲状腺TI-RADS 3、4级结节的校正及鉴别诊断价值。结果常规超声TI-RADS分级评估甲状腺结节良恶性与手术病理级型比较,差异无统计学意义(χ~2=3.56,P=0.06)。对于直径1cm的甲状腺TI-RADS 3、4级结节,与常规超声TI-RADS分级相比,CEUS评分及CEUS校正后TI-RADS分级的诊断准确率差异均有统计学意义(P=0.03、0.01);对于直径≤1cm的微小乳头状癌,差异均无统计学意义(P=0.25、1.00)。ROC曲线分析显示,对于甲状腺TI-RADS 3、4级结节,常规超声TI-RADS分级、CEUS评分、CEUS校正后TI-RADS分级的ROC曲线下面积分别为0.64、0.75、0.81时,截断值分别为TI-RADS 4a级、1分、TI-RADS 4a级,评估结节良、恶性的敏感度、特异度分别为45.3%、80.0%,69.3%、65.0%,82.7%、60.0%。CEUS评分、CEUS校正后TI-RADS分级与常规超声TI-RADS分级的曲线下面积的差异有统计学意义(P均0.05),CEUS评分与CEUS校正后TI-RADS分级的曲线下面积差异无统计学意义(P=0.23)。结论 CEUS对甲状腺TIRADS 3、4级结节具有校正及提高鉴别诊断的价值。
[Abstract]:Objective to evaluate the value of CEUS in the diagnosis of thyroid TI-RADS 3 grade 4 nodule. Methods the CEUS findings of 95 cases of thyroid nodule with grade 3 of TIRADS 3 or grade 4 diagnosed by conventional ultrasound were retrospectively analyzed. The value of CEUS in the correction and differential diagnosis of thyroid TI-RADS 3 or 4 grade nodule was analyzed. Results there was no significant difference between benign and malignant thyroid nodules by conventional ultrasound TI-RADS grading (蠂 2 / 3.56) and thyroid TI-RADS grade 3 / 4 nodule with diameter of 1 cm (蠂 2 / 3.56). Compared with the conventional TI-RADS grade, the diagnostic accuracy of CEUs and TI-RADS after CEUS correction were significantly higher than that of conventional ultrasound, and there was no significant difference in the diagnosis accuracy of P0. 03 or 0. 01% for small papillary carcinoma with diameter 鈮，
