【摘要】：目的评价桥本甲状腺炎(HT)背景下超声造影(CEUS)对甲状腺结节的诊断价值。方法回顾性分析了48例HT患者共62个结节的CEUS特征,计算增强模式及增强程度对HT背景下甲状腺恶性结节的诊断价值。结果增强程度(P=0.002)和增强模式(P0.001)在HT背景下甲状腺良、恶性结节组间差异有统计学意义。不均匀增强诊断HT背景下甲状腺恶性结节的敏感性、特异性、阳性预测值、阴性预测值和准确性分别为97.6%、85.7%、93.0%、94.7%和93.5%。低增强诊断HT背景下甲状腺恶性结节的敏感性、特异性、阳性预测值、阴性预测值和准确性分别为85.4%、52.4%、77.8%、64.7%和74.2%。结论不均匀增强对于HT背景下甲状腺恶性结节具有较好的诊断价值。对于常规超声诊断困难的甲状腺结节,CEUS可以提高诊断的准确性。
[Abstract]:Objective to evaluate the value of contrast-enhanced ultrasonography (CEUs) in the diagnosis of thyroid nodules in the background of Hashimoto's thyroiditis. Methods the CEUS features of 62 thyroid nodules in 48 patients with HT were retrospectively analyzed. The diagnostic value of enhancement model and enhancement degree for thyroid malignant nodule in HT background was calculated. Results the enhancement degree was 0.002) and the enhancement model was P0.001) the thyroid gland was benign in HT background. The sensitivity, specificity, positive predictive value of thyroid nodule in the background of HT were detected by non-uniform enhancement. The negative predictive value and accuracy were 97.6% and 93.07%, respectively. The sensitivity, specificity and positive predictive value of low contrast enhancement in the diagnosis of thyroid malignant nodules in the background of HT were 94.7% and 93.5%, respectively. The negative predictive value and accuracy were 85.4% and 74.7%, respectively. Conclusion uneven contrast enhancement has a good diagnostic value for thyroid malignant nodules with HT background. CEUs can improve the diagnostic accuracy for thyroid nodule with difficulty in conventional ultrasound diagnosis. [WT5 "HZ] [WT5" BZ] [WT5 "BZ] [WT5" BZ] [WT5BZ] [WT5 "BZ] the negative predictive value and accuracy were 64.7% and 74.2%, respectively.
