常规超声及超声弹性成像联合超声引导下细针穿刺细胞学检查对甲状腺结节的诊断意义

Diagnostic value of conventional ultrasound, ultrasonic elastography and ultrasound-guided fine needle aspiration cytology on thyroid nodules

目的 探讨常规超声、超声弹性成像(UE)、超声引导下细针穿刺细胞学检查(UG-FNAC)三者联合对甲状腺结节的诊断价值。方法 收集150例行常规超声、UE和UG-FNAC甲状腺结节患者的临床资料;把常规超声联合UE定义为对照组,常规超声、UE、UG-FNAC三者联合定义为观察组。对比两组的诊断效能、漏诊和误诊情况。结果 150例共有甲状腺结节172个,其中恶性150个(87.2%),良性22个(12.8%)。观察组灵敏度、预测准确性和阴性预测值均明显高于对照组(P<0.05),而漏诊率明显低于对照组(P<0.05)。结论 常规超声、UE、UG-FNAC三者联合可以提高甲状腺结节的诊断效能。

Objective To investigate the diagnostic value of combined conventional ultrasound(CU), ultrasonic elastography(UE) and ultrasound-guided fine needle aspiration cytology(UG-FNAC) on thyroid nodules. Methods Clinical data of 172 patients with thyroid nodules undergoing CU, UE and UG-FNAC were collected. All patients. Combined CU and UE was defined as control group, while combined CU, UE and UG-FNAC as observation group. Diagnostic efficacy,missed diagnosis and misdiagnosis were compared between two groups. Results There were 172 thyroid nodules in 150cases, of which 150(87.2%) malignant and 22(12.8%) benign nodules. Compared with control group, sensitivity, predictive accuracy and negative predictive value were higher(P<0.05), while missed diagnosis was lower(P<0.05) in observation group.Conclusion Combined CU, UE and UG-FNAC can improve the diagnostic efficiency of thyroid nodules.
