Abstract:
Objective To explore the diagnostic value of ultrasound in thyroid nodular disease.Methods Eighty-seven patients with thyroid nodule in hospital from 2010-2011 were taken ultrasound examination,including 23 cases with benign nodules and 64 cases with malignant nodules.Univariate analysis and mutivariate Logistic regression analysis were taken to test the ultrasonic index (internal echo,boundary,size,shape,microcalcifications,and aspect ratio) for discovery of the best diagnostic ultrasonic index to identify benign and malignant nodules.Results The ultrasound in the patients with malignant thyroid nodules showed the hypoecho,unclear border,irregular shape,microcalcifications,low blood supply,the aspect ratio ＞ 1.The ultrasound in the patients with benign thyroid nodules showed high or equal echo,clear border,regular shape,high blood supply,and the aspect ratio≤ 1.The ultrasonic indices between two groups had statistically significant difference (P ＜ 0.05).The shape and microcalcifications were the best ultrasonic diagnostic index to indentify the benign and malignant nodules with an EXP(B) 20.12 and 19.14,respectively.Conclusions The ultrasound is helpful in the diagnosis of thyroid nodular disease and identification of benign and malignant thyroid nodules.The ultrasonic images are the basic data for the clinical diagnosis of thyroid nodules.
