甲状腺乳头状癌的灰阶超声造影特征与颈部淋巴结转移的关系
Correlation between gray scale contrast-enhanced ultrasonographic characteristics of papillary thyroid carcinoma and cervical lymph node metastasis
摘要
Abstract
Objective To investigate the correlation between gray scale contrast-enhanced ultrasonographic characteristics of papillary thyroid carcinoma (PTC) and cervical lymph node metastasis. Methods Gray scale contrastenhanced ultrasonography was performed in 49 patients with 50 PTC lesions. The patients were categorized into 2 groups,with no lymph node metastases and with lymph node metastases. Gray scale contrast-enhanced ultrasonography was used for examining the perfusion of cancer nodules and the time-intensity curve (TIC) of contrast enhancement was analyzed,and then to study the correlation between the characteristics of gray scale contrast-enhanced ultrasonography and cervical lymph node metastasis. Results The correlation between characteristics of gray scale contrast-enhanced ultrasonography and cervical lymph node metastasis was mainly in the perfusion dynamics and the time begin to enhance, time to peak intensity and time delay for begin of enhancing in TIC. Conclusions Some characteristics of gray scale contrastenhanced ultrasonography could predict in certain degree the occurrence of cervical lymph node metastasis in papillary thyroid cancer and provide some references for the selection of appropriate surgical mode.关键词
