The aim of the present study is to demonstrate the rating of low flow color duplex echography as a new technique in the preoperative staging of head and neck cancer.
Forty-four patients with squamous cell carcinomas of the oral cavity, oropharynx, and hypopharynx were examined. Gray scale imaging as well as color duplex scan with doppler spectrum quantification were performed on each patient using a Siemens Quantum 2000 duplex scan with 7.5 MHz linear array.
Squamous cell carcinomas of the upper aerodigestive tract as well as their metastases are poorly vascularized but show irregular vascular patterns. In comparison to gray scale echography estimation of tumor borderline is improved by imaging of peripheral tumor vessels. Furthermore, imaging of irregular central tumor vessels in metastatic lymphatic nodes renders important information for N-staging.
Thus color duplex echography should be recommended for routine application in preoperative head and neck tumor staging.
本研究的目的是论证低流量彩色双功超声成像作为一种新技术在头颈部癌术前分期中的应用价值。
对44例口腔、口咽和下咽鳞状细胞癌患者进行了检查。使用配备7.5 MHz线性阵列的西门子Quantum 2000双功超声扫描仪对每位患者进行了灰阶成像以及带有多普勒频谱定量分析的彩色双功扫描。
上呼吸消化道鳞状细胞癌及其转移灶血供较差，但血管形态不规则。与灰阶超声相比，通过对肿瘤周边血管成像可更准确地估计肿瘤边界。此外，转移性淋巴结内不规则的中央肿瘤血管成像可为N分期提供重要信息。
因此，彩色双功超声成像应推荐用于头颈部肿瘤术前分期的常规检查。
