超声造影判定甲状腺“温结节”的性质

Contrast enhanced ultrasound in diagnosis of thyroid "warm" nodule

目的:探讨应用超声造影鉴别诊断放射性核素显像表现为"温结节"的甲状腺结节的良恶性的价值。方法:回顾性分析97例ECT表现为"温结节"病变的超声造影表现,判定结节良恶性,并与病理结果相对照。结果:97例甲状腺结节中,13例超声造影表现为不均匀低增强,诊断为恶性;84例表现为均匀等/高增强或低增强,诊断为良性。超声造影诊断甲状腺恶性结节的灵敏度为91.67%,特异度97.65%,准确率96.91%。结论:超声造影可用以鉴别诊断放射性核素显像表现为"温结节"的甲状腺结节的良恶性。

Objective：To explore the value of CEUS in differential diagnosis of malignant and benign thyroid ＂ warm＂ nodule confirmed with radionuclide imaging.Methods：CEUS finding of 97 thyroid ＂warm＂ nodulse were analyzed retrospectively.The differential diagnosis was performed to CEUS and compared with surgical-pathologic results.Results：Of 97 cases 13 thyroid nodules showed uneven hypoenhancement and were diagnosed as malignancy,while the remaining 84 nodules showed even isoechoic/hyperechoic or hypoenhancement and were diagnosed as benign.The sensitivity,specificity,accuracy of CEUS in differentiating thyroid malignant nodules were 91.67％,97.65％,96.91％.Conclusion：CEUS can be used to differentiate benign and malignant thyroid ＂ warm＂ nodules confirmed with radionuclide imaging.
