三维断层超声成像联合超声造影在DTC评估中的价值

Value of Three-dimensional Tomographic Ultrasound Combined with Contrast-enhanced Ultrasound in the Evaluation in Patients with DTC

本文探讨三维断层超声成像联合超声造影检查在分化型甲状腺癌(DTC)患者颈部淋巴结性质及腺体外侵犯评估中的价值。选取DTC患者93例,给予三维断层超声成像联合超声造影检查。转移性淋巴结长短径之比≤1.5、淋巴门结构消失、混杂血流、向心性造影、非均匀性造影的比例明显高于非转移性淋巴结(P<0.05);转移性淋巴结峰值强度(PI)、平均通过时间(MTT)和达峰时间(TTP)明显低于非转移性淋巴结(P<0.05);Logistic回归分析显示:长短径之比、淋巴门结构、造影模式、造影程度、PI、MTT和TTP是转移性淋巴结的影响因素(P<0.05);Logistic回归分析显示:结节延伸突破甲状腺被膜、MTT和TTP是转移性淋巴结的影响因素(P<0.05)。三维断层超声成像联合超声造影检查评估DTC患者颈部淋巴结转移及腺体外侵犯中有较好的效果。

The purpose of this study was to investigate the value of three-dimensional tomographic ultrasound imaging combined with contrast-enhanced ultrasound in the evaluation of cervical lymph node properties and extra-adenal invasion in patients with differentiated thyroid cancer(DTC).Nighty-three patients with DTC were selected,three dimensional tomographic ultrasound imaging combined with contrast-enhanced ultrasound was performed.The ratio of long to short diameter was lower than 1.5,disappearance of lymphatic portal structure,mixed blood flow,centripetal angiography,heterogeneous angiography of metastatic lymph nodes were significantly higher than those of non metastatic lymph nodes(P<0.05).Logistic regression analysis showed that the ratio of long to short diameter,the structure of lymph nodes,the mode of angiography,the degree of angiography,PI,MTT and TTP were the influencing factors of metastatic lymph nodes(P<0.05).Logistic regression analysis showed that the extension and breakthrough of thyroid capsule,MTT and TTP were the influencing factors of metastatic lymph nodes(P<0.05).Three dimensional tomographic ultrasound combined with contrast-enhanced ultrasound has a good effect in the evaluation of cervical lymph node metastasis and extra-glandular invasion in patients with DTC.
