本文应用彩阶Ｂ超的七段编码技术对涎腺肿块进行了研究。受检者共３５人，其中混合瘤１６例、腺淋巴瘤８例、恶性肿瘤７例、囊肿４例，所有病例均经手术和病理证实。结果显示：混合瘤内部回声的平均色量级高于腺淋巴瘤（Ｐ＜０．０１），与恶性肿瘤相近（Ｐ＞０．０５）。其色量级之差比腺淋巴瘤大，但小于恶性肿瘤，囊肿回声多为暗区（３／４），只有１例为飘浮的兰色光点。混合瘤、腺淋巴瘤的境界以锐利型和过渡型为主（２１／２４），而恶性肿瘤则以镶嵌型为主（６／７），囊肿多为锐利型，只有１例伴感染的为过渡型。涎腺肿块的境界类型是诊断涎腺肿块的最有价值的指标。本文结果表明：彩阶有助于对涎腺肿块内部回声的定量及境界的类型作出较为客观的评估，以提高诊断的准确率。
In this paper, color Doppler ultrasound B-segment coding technique of salivary gland mass was studied. A total of 35 subjects, including 16 mixed tumor, adenolymphoma in 8 cases, 7 cases of malignant tumors, cysts in 4 cases, all cases were confirmed by surgery and pathology. The results showed that the average internal color of mixed tumor was higher than that of adenolymphoma (P <0.01) and similar to that of malignant tumor (P> 0.05). The magnitude of the difference between the magnitude of glandular lymphoma, but less than malignant tumors, mostly dark cysts echo (3/4), only 1 case of floating blue light spots. Mixed tumor, gland lymphoma in the realm of sharp and transitional type based (21/24), while the malignant tumor mosaic (6/7), cyst mostly sharp type, only 1 case of infection with Transitional The realm of salivary gland mass is the most valuable indicator for the diagnosis of salivary gland mass. The results show that: Color Doppler echocardiography helps to quantify the echo within the salivary gland mass and the realm of the type to make a more objective assessment to improve the diagnostic accuracy.
