甲状腺结节的高频超声声像图特点及彩色多普勒血流特征分析

Analysis of Characteristics of High-frequency Ultrasonography and Color Doppler Blood Flow of Thyroid Nodules

目的探究甲状腺结节的高频超声声像图特点结合彩色多普勒血流特征,从而鉴别判断甲状腺结节的良恶性。方法以最终术后病理结果为依据,按良恶性病变的不同,将2017年1月~2018年5月接收的131例甲状腺结节患者分为甲状腺良性结节组和甲状腺恶性结节组两组。甲状腺良性结节组68例,甲状腺恶性结节组63例。均接受高频超声及彩色多普勒超声检查及诊断。观察两组高频超声声像图特点结合彩色多普勒血流特征。及单一诊断与联合诊断的复合率情况。结果两组患者在高频超声声像图特征:边界不整、微钙化灶、淋巴结节转移、内部低回声、周围无回声方面及血流分布级别和血流参数方面有着明显差异,具有统计学意义(P<0.05);高频超声结果显示符合病理诊断结果符合率为88.55%;彩色多普勒超声结果符合率为90.08%,两种超声诊断联合诊断结果符合病理诊断符合率为98.47%,联合诊断的符合率明显高于单一的诊断,比较差异具有统计学意义(P<0.05)。结论良性与恶性甲状腺结节存在不同的高频超声声像图及彩色多普勒血流特征,为临床鉴别诊断提供了可靠的依据,且两种超声联合诊断评估可提高诊断的符合率。

Objective Exploring the characteristics of high-frequency ultrasound imaging of thyroid nodules combined with color Doppler blood flow characteristics,so as to distinguish and judge the benign and malignant thyroid nodules.Methods Based on the final postoperative pathological results,according to the different benign and malignant lesions,131 patients with thyroid nodules received in our hospital from January 2017 to May 2018 were divided into benign thyroid nodules and malignant thyroid nodules Group two groups.There were 68 cases in the benign thyroid nodule group and 63 cases in the malignant thyroid nodule group.All received high-frequency ultrasound and color Doppler ultrasound examination and diagnosis.Observe the characteristics of two groups of high-frequency ultrasound images combined with color Doppler blood flow characteristics.And the compound rate of single diagnosis and combined diagnosis.Results The two groups of patients had significant differences in the characteristics of high-frequency ultrasound sonography:border irregularities,microcalcifications,lymph node metastasis,internal hypoechoic,peripheral anechoic,and blood flow distribution levels and blood flow parameters.Significance(P<0.05);high-frequency ultrasound results showed that the coincidence rate of pathological diagnosis was 88.55%;the coincidence rate of color Doppler ultrasound results was 90.08%,and the combined diagnosis results of the two ultrasounds were consistent with the pathological diagnosis coincidence rate of 98.47%.The coincidence rate of combined diagnosis was significantly higher than that of single diagnosis,and the difference was statistically significant(P<0.05).Conclusions Benign and malignant thyroid nodules have different high-frequency ultrasound sonograms and color Doppler blood flow characteristics,which provide a reliable basis for clinical differential diagnosis,and the combined diagnosis and evaluation of the two ultrasounds can improve the diagnostic coincidence rate.
