Clinical Significance of High Frequency Ultrasound in Detection of Thyroid Nodule Calcification

Objective: To investigate the clinical significance of thyroid calcification in the differential diagnosis of thyroid carcinoma.Methods: The clinical data of 77 patients(male:20,female:57) with thyroid nodules,who were confirmed by preoperative ultrasonic examination and postoperative pathological results,were retrospectively analysed.Results: Among the patients,there were 20 with benign nodules,56 with malignant tumor,and 1 with precancerous lesion.In this study,calcification rates in benign and malignant diseases were 10% and 14.28% respectively,with significant difference.Conclusion: According to the size of thyroid nodule calcification,whether malignant disease or not can be diagnosed,so if micro-calcification in thyroid nodules is detected by preoperative ultrasound,malignant tumor of thyroid should be highly doubted and paid more attention to,especially for the young or patients with single nodule.
