Using a Toshiba SSA-270A Colour Duplex Scanner, 15 patients with suspected parotid and submandibular gland tumours had preoperative duplex scanning done. Peak systolic doppler shifts (fmax) were recorded and their vascularity was also subjectively scored. There were no arteries identified within the substance of contralateral normal glands. All recordings were analysed retrospectively and an independent histological assessment of tumours was made. Pleomorphic adenomas (n = 9) had a median peak systolic frequency (fmax) of 0.8 kHz, while adenolymphomas (n = 4) had a fmax of 1.65 and the two malignant tumours had fmax of 4.5 (P = 0.007 Kruskal-Wallis test). There appears to be a strong correlation between the fmax and the subjective vascular score (Corr 0.92). Colour duplex scanning is a non-invasive procedure which may be of help in the preoperative assessment of salivary gland tumours.
使用一台东芝SSA - 270A彩色双功扫描仪，对15例疑似腮腺和颌下腺肿瘤的患者进行了术前双功扫描。记录收缩期峰值多普勒频移（fmax），并对其血管分布进行主观评分。在对侧正常腺体实质内未发现动脉。所有记录均进行回顾性分析，并对肿瘤进行独立的组织学评估。多形性腺瘤（n = 9）的收缩期峰值频率（fmax）中位数为0.8 kHz，腺淋巴瘤（n = 4）的fmax为1.65，两个恶性肿瘤的fmax为4.5（Kruskal - Wallis检验，P = 0.007）。fmax与主观血管评分之间似乎存在很强的相关性（相关系数0.92）。彩色双功扫描是一种非侵入性检查方法，可能有助于唾液腺肿瘤的术前评估。
