二维联合彩色多普勒超声对甲状腺癌的诊断价值研究

Diagnostic Value of Two-dimensional Combined Color Doppler Ultrasonography in Thyroid Cancer

目的:分析二维联合彩色多普勒超声在甲状腺癌诊断中的应用价值。方法:选取2023年5月—2024年6月绥化市第一医院收治的68例疑似甲状腺癌患者为研究对象,患者均进行二维超声、彩色多普勒超声、病理活检,以病理诊断结果为“金标准”,对比单一超声与联合超声检查诊断结果及诊断效能。比较不同性质肿瘤在二维超声中声像回声表现及彩色多普勒超声参数。结果:68例疑似甲状腺癌患者经病理确诊阳性41例,阴性27例。二维联合彩色多普勒超声检查灵敏度高于二维超声、彩色多普勒超声,特异度低于彩色多普勒超声(P<0.05)。恶性肿瘤低回声、混合回声占比高于良性肿瘤,等回声占比低于良性肿瘤(P<0.05)。恶性肿瘤阻力指数、收缩期峰值流速高于良性肿瘤(P<0.001)。结论:在对疑似甲状腺癌患者进行诊断时,不同超声检查均有各自的诊断价值,联合应用二维超声、彩色多普勒超声可提高疾病诊断效能,判断肿瘤性质。

Objective:To analyze the application value of two-dimensional combined color Doppler ultrasonography in the diagnosis of thyroid cancer.Methods:Sixty-eight patients with suspected thyroid cancer admitted to the Suihua First Hospital from May 2023 to June 2024 were selected as the study objects.Two-dimensional ultrasound,color Doppler ultrasonography and pathological biopsy were performed on all patients.Taking the pathological diagnosis as the"gold standard",the diagnostic results and diagnostic efficacy of single ultrasound and combined ultrasound were compared.The echo performance and color Doppler ultrasonography parameters of different tumors in two dimensional ultrasound were compared.Results:Of 68 suspected thyroid cancer patients,41 were positive and 27 were negative.The sensitivity of ultrasound combined color Doppler ultrasonography was higher than that of two-dimensional ultrasound and color Doppler ultrasonography,and the specificity was lower than that of color Doppler ultrasonography(P<0.05).The proportion of low echo and mixed echo in malignant tumor was higher than that in benign tumor,and the proportion of equal echo was lower than that in benign tumor(P<0.05).The resistance index and systolic peak velocity of malignant tumors were higher than those of benign tumors(P<0.001).Conclusion:In the diagnosis of suspected thyroid cancer patients,different ultrasonography has its own diagnostic value.The combined application of two-dimensional ultrasound and color Doppler ultrasonography can improve the diagnostic efficiency of disease and judge the nature of tumor.
