摘　　要：目的探讨应用CEUS鉴别诊断放射性核素显像表现为"冷结节"的甲状腺结节性病变的良恶性的价值。方法回顾性分析115例ECT表现为"冷结节"患者的170个甲状腺结节性病变的CEUS表现,判定结节良恶性,并与病理结果相对照。结果 170个甲状腺结节中,39个CEUS表现为不均匀弱增强,诊断为恶性;131个表现为与周围甲状腺实质同步等/高增强或无增强,诊断为良性。CEUS诊断甲状腺恶性结节的敏感度为91.67%(33/36),特异度为95.52%(128/134),准确率为94.71%(161/170)。结论 CEUS可用以鉴别诊断放射性核素显像表现为"冷结节"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 ＂cold＂ nod- ule confirmed with radionuclide imaging. Methods CEUS findings of totally 170 thyroid nodules in 115 patients with thy- roid ＂cold＂ nodule were analyzed retrospectively. The differential diagnosis was performed according to CEUS and com- pared with surgical-pathologic results. Results Among 170 thyroid nodules, 39 showed uneven hypoenhancement and were diagnosed malignancy, while the remaining 131 nodules showed synchronous isoechoic/hyperechoic or non-enhanced com- pared to the surrounding thyroid, and were diagnosed benign. The sensitivity, specificity, and accuracy of CEUS in differ- entiating thyroid malignant nodules was 91.67%（33/36）, 95.52% （128/134） and 94.71% （161/170）, respectively. Con- clusion CEUS can be used to differentiate benign and malignant thyroid ＂cold＂ nodules confirmed with radionuclide ima- ging.
