彩色多普勒超声诊断良恶性甲状腺结节的参考价值

目的分析良、恶性甲状腺结节的彩色多普勒超声表现,以提高超声诊断和鉴别诊断良、恶性甲状腺结节的价值。方法回顾性分析经手术、病理明确诊断的157个良、恶性甲状腺结节的彩色多普勒超声表现，良、恶性结节的形态、回声、钙化特点、彩色多普勒血流图血流信号分布等。结果157个甲状腺结节经病理诊断，其中 90个为良性结节，67个为恶性结节；本组病例彩色多普勒超声检查的特异性为92.2%，敏感性为80.6%，诊断符合率为87.2%；彩色多普勒超声图像显示甲状腺良、恶性结节的形态、边界、包膜、回声、血流信号分布、内部钙化情况、血流阻力指数值比较，差异比较均具有统计学意义（P<0.05）。结论彩色多普勒超声可诊断甲状腺病变，依据重要的参考指标，可评价甲状腺结节的良、恶性。

Color Doppler ultrasound in diagnosis of benign and malignant thyroid nodules

ObjectiveTo analyze the color Doppler ultrasound of benign and malignant thyroid nodules, and improve the value of ultrasound diagnosis and differential diagnosis of benign and malignant thyroid nodules. MethodsThe color Doppler ultrasound image features of 157 patients with benign and malignant thyroid nodules diagnosed by surgery and pathology were analyzed retrospectively, to evaluate the relationship between the shape, echo, calcification, color Doppler flow imaging blood flow signal distribution and benign or malignant nodules. ResultsAmong 157 thyroid nodules, 90 were benign and 67 were malignant. The specificity, sensitivity and coincidence rate of color Doppler ultrasound were 92.2%, 80.6% and 87.2%, respectively. Color Doppler ultrasound images showed statistically significant differences in benign and malignant thyroid in morphology, boundary, capsule, echo, blood flow signal distribution, internal calcification and blood flow resistance index values (P<0.05). ConclusionColor Doppler ultrasound can diagnose thyroid lesions, and it can evaluate the benign and malignant thyroid nodules based on above reference indicators.
