Objective To investigate the color Doppler flow imaging ( cdfi) in benign and malignant thyroid nodule judgment of the clinical application value .Meth-ods Using the color Doppler flow imaging ( cdfi) in 57 cases of 74 patients with thyroid nodular lesions on preoperative examination ,the nodules were observed the mor-phology,blood flow within the boundary,echo and enchantment,and compared with postoperative pathological diagnosis,the pathological examination results shall pre-vail.Results Color Doppler ultrasound examination in 43 patients with thyroid nodules are benign nodules,were 51,14 cases malignant nodules,23 lesions;Pathological results for thyroid nodules are benign nodules 45 cases,lesions 49,12 cases of malignant nodules,25 lesions.Benign thyroid nodules audio -visual learning main show is comparatively rules form,clear boundary,internal for high echo,and the lack of blood flow in nodules;Malignant nodules audiovisual learning performance for shape is ir-regular,fuzzy boundaries is not clear,the internal for irregular low echo,and abundant blood flow within nodules.The sensitivity of color Doppler ultrasonic diagnosis of thyroid nodule was 82.6%,88.2%,86.5% accuracy.Conclusion Color Doppler flow imaging(cdfi)in the differential diagnosis of benign and malignant thyroid nodule with high clinical value,worthy of application.
