目的对彩色多普勒超声在甲状腺结节性病变诊断中的应用价值进行分析和探讨。方法运用随机抽样的方法选择50例甲状腺结节性病变患者,均采用彩色多普勒超声进行检查,观察甲状腺及结节的大小、结节内部回声、周边回声、结节的血供,并与术后病理诊断结果进行对比。结果 50例甲状腺结节患者中,病理诊断显示6例患者为恶性病变,44例患者为良性病变;彩色多普勒超声诊断显示8例患者为恶性病变,42例患者为良性病变,其中1例甲状腺囊腺瘤和1例甲状腺腺瘤均误诊为甲状腺癌,误诊率为4.0%,诊断准确率为96.0%。结论彩色多普勒超声应用于甲状腺结节性病变诊断中,具有快速、无创、简单、准确、有效等优点,能为临床提供客观的诊断依据,可作为甲状腺结节的首选辅助诊断手段。 Objective To analyze and discuss the value of color Doppler sonography in the diagnosis of thyroid nodular lesions. Methods Fifty patients with thyroid nodular lesions were selected by random sampling. Color Doppler echocardiography was used to examine the thyroid and nodule size, internal nodular echo, peripheral echoes and nodule blood supply. Postoperative pathological diagnosis results were compared. Results Among the 50 cases of thyroid nodules, pathological diagnosis showed that 6 cases were malignant and 44 cases were benign. Color Doppler ultrasound showed 8 cases were malignant and 42 cases were benign. Among them, 1 case Thyroid cystadenoma and thyroid adenoma were misdiagnosed as thyroid cancer, the misdiagnosis rate was 4.0%, the diagnostic accuracy was 96.0%. Conclusion The application of color Doppler ultrasound in the diagnosis of thyroid nodules is rapid, noninvasive, simple, accurate and effective. It can provide objective diagnosis for clinical diagnosis and can be used as the first choice of auxiliary diagnosis for thyroid nodules.
