Title: Diagnostic value of Ultrasonography to metastasis of cervical lymph nodes in patients with thyroid carcinoma
Abstract: Objective To investigate the diagnostic value of color doppler ultrasonography in the cervical lymph node metastases of thyroid carcinoma. Methods Preoperative ultrasonographic findings of 72 thyroid carcinoma patients confirmed by surgery and pathology were analyzed retrospectively. The locations,sizes,two-dimensional sonographic features and blood flow information of the lymph nodes were analysized by comparing with post-operative pathological results. Results The accordance rate was 77.9% between the ultras-onography and pathological results of metastatic lymph nodes.The metastasis existed in the lymph nodes with the sonographic features, which were a less than 2 ratio of long to short axis,absence of an echogenic hilum,microcalcification,cystis degeneration and affluent vascular pattern. The differences between the malignant and benign hyperplastic groups for all the above-mentioned index was statistically significant (P 0.05). The blood flow peak systolic velocity (PSV) and resistance index (RI) in malignant groups were significantly higher than those in benign hyperplastic groups ( P 0.05). Conclusion High-frequency color doppler ultrasound is convenient and effective in detecting metastatic lymph nodes in patients with thyroid carcinoma and has high diagnostic accuracy and important guiding significance in clinic.
