Abstract:
Objective To explore the role of ultrasound-guided core needle biopsy in diagnosis and treatment of thyroid nodules.Methods 778 cases undergoing ultrasound-guided core needle biopsy in our department from Jan.2012 to Dec.2014 were retrospectively analyzed,and the sensitivity,specificity and accuracy were calculated.Results All the patients were operated successfully.Except for 21 nodules undiagnosed,16.4% (124/757) were histologically diagnosed as malignant and 83.6% (633/757) were benign.15 samples of the 124 malignant nodules were less than 10 millimeter in diameter.The sensitivity,specificity and accuracy were 100%,94.8% and 95.6%,respectively.Of the ultrasound features,blood flow,boundary,internal situation and calcification were statistically significant between benign and malignant nodules,but not so between the groups of different greatest dimentions.Conclusion Ultrasound-guided core needle biopsy is safe and effective for obtaining thyroid nodule tissue,and it is helpful for diagnosis of thyroid diseases.
