Diagnosis and differential diagnostic value of color doppler ultrasound for benign and malignant thyroid nodules / 中国现代医生

ABSTRACT

Objective To investigate the diagnosis and differential diagnosis value of benign and malignant thyroid ul-trasound nodules. Methods A retrospective analysis of the sonographic manifestations and CDFI showed changes of hemodynamic parameters of 60 patients with benign and malignant thyroid nodules confirmed by pathology from Jan-uary 2009 to January 2014 in our hospital. Results Sixty patients included benign lesions 48 cases (50 nodules),26 cases nodular goiter, 22 cases thyroid adenoma; malignant lesions in 12 cases (14 nodules), included papillary thyroid carcinoma 10 patients, follicular carcinoma 1 case, metastatic carcinoma 1 case. 48 cases of benign nodules blood dy-namics grade 0 10 cases, grade Ⅰ 30 cases, grade Ⅱ 7 cases, grade Ⅲ 1 case, in which the following grade Ⅱ(83.3%);12 cases of malignant nodules hemodynamic classification grade 0 0 cases, grade Ⅰ1 case, gradeⅡ3 cas-es, grade Ⅲ 8 cases, grade Ⅲ accounted for 75%. PSV, RI of malignant nodules group was significantly higher than benign nodules, EDV of malignant nodules group was significantly lower than benign nodules group, the difference was significant (P<0.05). Conclusion Benign and malignant thyroid nodules ultrasound diagnosis is based on two-dimen-sional ultrasound should be performance-based, combined with color doppler flow imaging and pathology can improve the accuracy of diagnosis. Therefore, familiar with the sonographic appearance of thyroid nodules and differential points, and closely linked to a comprehensive analysis of the clinical data , in order to reduce the incidence of misdiag-nosis.
