目的探讨甲状腺癌术后随诊中彩色多普勒超声及超声弹性成像的价值。方法选取80例甲状腺癌患者为研究对象,分别采用常规高频彩色多普勒超声诊断、超声弹性成像诊断及彩色多普勒超声联合超声弹性成像诊断,分析三种诊断方法的结果。结果常规高频彩色多普勒超声的诊断准确率为75.0%(60/80),误诊率为25.0%(20/80);超声弹性成像的诊断准确率为60.0%(48/80),误诊率为40.0%(32/80);彩色多普勒超声联合超声弹性成像的诊断准确率为90.0%(72/80),误诊率为10.0%(8/80);彩色多普勒超声联合超声弹性成像的诊断准确率高于常规高频彩色多普勒超声和超声弹性成像的诊断准确率,差异有统计学意义(P<0.05)。结论在甲状腺癌检查、诊断过程中,单独使用超声弹性成像诊断或者彩色多普勒超声进行诊断有一定的局限性,而将两者联合使用可以有效提升甲状腺癌诊断的准确性,具有较高的临床推广应用价值。
Objective To investigate the value of color Doppler ultrasound and ultrasound elastography in the follow-up of thyroid cancer. Methods Eighty patients with thyroid cancer were enrolled in this study. They were diagnosed by conventional high-frequency color Doppler ultrasound, ultrasound elastography and color Doppler ultrasound combined with elastography. The results of three diagnostic methods were analyzed. Results The diagnostic accuracy of conventional high-frequency color Doppler ultrasound was 75.0% (60/80) and the misdiagnosis rate was 25.0% (20/80). The diagnostic accuracy of ultrasound elastography was 60.0% (48/80) The diagnostic accuracy of color Doppler ultrasound combined with ultrasound elastography was 90.0% (72/80) and the rate of misdiagnosis was 10.0% (8/80). The color Doppler ultrasound combined with ultrasound The diagnostic accuracy of elastography is higher than the diagnostic accuracy of conventional high-frequency color Doppler ultrasound and elastography, the difference was statistically significant (P <0.05). Conclusions In diagnosis and diagnosis of thyroid cancer, ultrasound elastography alone or color Doppler ultrasound has some limitations. Combined use of the two can effectively improve the diagnostic accuracy of thyroid cancer with high Clinical application value.
