CEUS灌注模式鉴别诊断甲状腺良恶性结节

CEUS perfusion patterns in differential diagnosis of benign and malignant thyroid nodules

目的探讨CEUS灌注模式鉴别诊断甲状腺良恶性结节的价值。方法回顾性分析111例甲状腺结节患者(111个结节)的颈部CEUS图像及临床资料,通过评价造影灌注模式判断结节的良恶性。以病理结果为最终诊断标准,评价CEUS对甲状腺良恶性结节的诊断效能。结果病理诊断甲状腺良性结节14例,恶性结节97例。CEUS诊断甲状腺结节良恶性的敏感度为92.78%(90/97),特异度64.29%(9/14),准确率89.19%(99/111),阳性预测值94.74%(90/95),阴性预测值56.25%(9/16)。结论 CEUS灌注模式对鉴别诊断甲状腺良恶性结节具有一定价值。

Objective To investigate the value of CEUS perfusion patterns in differential diagnosis of benign and malignant thyroid nodules.Methods CEUS images and clinical data of 111 patients with thyroid nodules (111 nodules) were retrospectively analyzed.Benign and malignant nodules were diagnosed through evaluating their contrast perfusion patterns.Taken pathology as the final diagnostic criteria,the efficacy of CEUS in differential diagnosis of benign and malignant thyroid nodules was evaluated.Results Totally 14 cases were diagnosed as benign nodules and 97 as malignant nodules.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of CEUS in differential diagnosis of benign and malignant thyroid nodules were 92.78%(90/97),64.29%(9/14),89.19%(99/111),94.74%(90/95) and 56.25%(9/16),respectively.Conclusion CEUS perfusion patterns are valuable in differential diagnosis of benign and malignant thyroid nodules.
