目的:通过临床病例资料分析,观察彩色多普勒超声在甲状腺良恶性肿瘤鉴别中的应用情况,为今后的诊断工作提供参考依据。方法:选取2013年1月至2013年12月期间我院收治的70例甲状腺肿瘤患者作为本组研究的观察对象,按照病理检查结果将其分为良性组(39例)与恶性组(31例),分别对两组患者的超声表现及诊断情况进行总结分析。结果:(1)病灶血流情况:良性组甲状腺肿瘤的血流最大速度为(0.17±0.07)m/s,明显低于恶性组(0.35±0.13)m/s;良性组甲状腺肿瘤的阻力指数为(0.66±0.13),明显高于恶性组(0.51±0.11)。(2)诊断正确率:彩超对良性甲状腺肿瘤的临床诊断正确率为82.05%(32/39),对恶性甲状腺肿瘤的诊断率为61.29%(19/31),良性肿瘤的诊断正确率明显高于恶性肿瘤,具有统计学意义,P<0.05。结论:彩超对甲状腺肿瘤的良、恶性诊断准确率较为理想,可以作为临床中鉴别甲状腺肿瘤性质的首选方法在临床中推广。
OBJECTIVE: To observe the application of color Doppler ultrasound in the differential diagnosis of benign and malignant thyroid tumors through clinical case data analysis, and provide reference for the future diagnosis. Methods: Seventy patients with thyroid neoplasm admitted to our hospital from January 2013 to December 2013 were selected as the observation subjects in this study. According to the results of pathological examination, they were divided into benign group (39 cases) and malignant group (31 cases ), Respectively, on the two groups of patients with ultrasound findings and diagnosis summary analysis. Results: (1) Focal blood flow: The maximum velocity of blood flow in benign group was (0.17 ± 0.07) m / s, which was significantly lower than that in malignant group (0.35 ± 0.13) m / s. The resistance index of benign group (0.66 ± 0.13), which was significantly higher than that in malignant group (0.51 ± 0.11). (2) The correct rate of diagnosis: The correct rate of color Doppler ultrasound in the diagnosis of benign thyroid tumors was 82.05% (32/39), the diagnosis rate of malignant thyroid tumors was 61.29% (19/31), and the diagnostic accuracy of benign tumors was significantly higher In malignant tumors, with statistical significance, P <0.05. Conclusion: The diagnostic accuracy of color Doppler ultrasonography for benign and malignant thyroid neoplasms is ideal and can be used as the first choice in the clinical diagnosis of thyroid neoplasms in clinic.
