目的：分析彩色多普勒超声对甲状腺良、恶性肿瘤鉴别诊断的价值。方法回顾分析我院2013年8月～2015年2月经手术确诊的252例甲状腺肿瘤患者的临床资料，且术前所有患者均采用彩色多普勒超声（CDFI）检查。结果恶性甲状腺肿瘤病灶III级彩色血流比例为70.2%（59/84），明显多于良性甲状腺肿瘤；良性肿瘤病灶I级彩色血流比例为75.0%（126/168），明显多于恶性肿瘤（P <0.05）。彩色多普勒超声对良、恶性甲状腺肿瘤的诊断准确率分别为95.8%、91.7%，P >0.05，差异无统计学意义。与良性肿瘤相比，恶性肿瘤的彩色血流显像具有走形不规则，分布不均匀、贯穿突破等特点。结论彩色多普勒超声诊断甲状腺肿瘤诊断准确率高，可有效鉴别肿瘤良、恶性的特点。%ObjectiveTo analyze the value of Color Doppler Ultrasound in the differential diagnosis of thyroid benign and malignant tumors.Methods A retrospective analysis of 252 cases of thyroid cancer patients in our hospital from august 2013 to February 2015 ,and al patients underwent preoperative Color Doppler Ultrasound (CDFI) examination.ResultsThe malignant thyroid tumors lesions grade III color flow ratio was 70.2% (59/84), significantly more than benign thyroid tumors; benign tumors lesions grade I color flow ratio was 75.0% (126/168), significantly more than the malignant tumors (P < 0.05). Color Doppler Ultrasound diagnostic accuracy of benign and malignant thyroid tumors was respectively 95.8%, 91.7%, P > 0.05, the difference was not statisticaly significant. Compared with benign tumors, malignant’s color flow imaging had irregular shape, uneven distribution ,throughout breakthrough and so on .Conclusion Color Doppler Ultrasound diagnosis of thyroid tumors with high diagnostic accuracy, which can discriminate benign or malignant tumors ,and other characteristics.
