Ultrasound-guided Core Needle Biopsy Evaluation Of Microcalcification Value In The Diagnosis Of The Thyroid

Objective:To explore ultrasound-guided core needle biopsy evaluation of microcalcification value in the diagnosis of the thyroid carcinoma.Methods:1. In62patients with thyroid nodules with calcification suspected lesions underwent ultrasound guide core needle biopsy, doperation and pathology biopsy results compared with the control, analysis of thyroid biopsy results and postoperative pathological results whether there are differences.2.According to the size of the nodules of calcification,It can be divided into thickcalcification (>1mm) and microcalcification(≤1mm), Compared with thick calcification and microcalcification in the thyroid benign and malignant nodules whethe there is a difference.Resluts:1. Ultrasound guided core needle biopsy accuracy was96.7%, the sensitivity was96%, the specificity was100%.2. The specificity of microcalcification in the diagnosis of thyroid carcinoma was95%, microcalcification in thyroid benign and malignant nodules ioccurrence rate compares difference to have statistical sense.3. The age<45years and≥45years in patients with thyroid carcinoma with calcification of thyroid tumor ratios were90.2%and61.9%, there was difference between two groups. 4. Male thyroid carcinoma with calcification incidence76%, thyroid cancer in women with calcification rate83.8%, no significant differences in two.Conclusions:1. Ultrasound-guided thyroid core needle biopsy has high, accuracy, sensitivity and specificity.2. On the age<45years old with calcification, especially malignant microcalcifications increased risk of thyroid nodule patients, should further consider biopsy, definite pathologic diagnosis3. The microcalcification is the imaging features of thyroid carcinoma, but it is not peculiar to thyroid cancer. Ultrasound guided core needle biopsy can make up for the deficiency of ultrasound, significantly increase the early diagnosis rate of thyroid cancer. With the high value of the preoperative diagnosis of thyroid cancer, has important significance for treatment of thyroid nodules.
