摘　　要：目的　探讨高频超声对腮腺恶性肿瘤的诊断价值。方法　 62例腮腺恶性肿瘤患者 ,应用高频超声观察肿瘤的外形、内部回声特点 ,彩色多普勒血流显像 (CDFI)观察肿瘤内血流信号 ,测频谱多普勒并探测腮腺旁淋巴结。结果　腮腺恶性肿瘤高频声像图特征 :形态分类圆型、分叶型、不规则型 ;边界分清楚、不清楚、浸润状 ;内部回声分不均匀低回声、点状或簇状强回声、囊实性、蜂窝状。CDFI显示点状、棒状血流信号 ,收缩期血流峰值 4.6～ 17.5cm /s ,阻力指数 0 .69～ 1.14。误诊为良性肿瘤 8例 ,诊断符合率为 87.1%。结论　腮腺恶性肿瘤的高频声像图表现有其共性和特异性 ;血流丰富程度 ,收缩期血流峰值。Objective To evaluate the value of high frequency color Doppler ultrasound in diagnosis of malignant tumor in the parotid gland.Methods High frequency ultrasound was used to observe shape and internal echo texture of tumor,color Doppler flow imaging(CDFI) was added to observe blood flow signal,peak systolic velocity(PSV) and resistance index(RI) were measured by pulsed wave Doppler, and lymphonodus around parotid gland were examined.Results The features of ultrasonography included round,lobulated and irregular shape.Three types of boundary were clear but not smooth,unclear,irregular and invasive.Internal echo texture included low and irregualr echo,cystic echo,spot like and intensive echo,honey comb like echo.CDFI showed spet like,stick like blood flow signal.PSV and RI were 4.6 17.5 cm/s,and 0.69 1.14 .Eight cases were misdiagnosed for benign tumor,the correspondent rate was 87.1% .Conclusions The high frequency ultrasonogram of malignant tumor in the parotid gland were similar and specific,adding the CDFI,PSV,RI and lymphonodus examination around the parotid gland may help to improve the diagnostic accuracy.
