对60例乳腺肿块患者的彩色多普勒信号进行了主观评价，并提出了一种定量显示血管密度的区域分级方法。在21例乳腺癌患者中，除1例外，其余均显示中或高血流，平均每平方厘米0.5个血管，彩色像素占图像面积的12.2%。在33例良性病变患者中，25例无血流，5例轻度至中度血流，平均每平方厘米0.01支血管，占图像面积的0.8%。直径小至10 mm的癌为血流阳性。仅在恶性肿瘤中观察到高速血流;在4例病例中观察到高速血流，可能是由于动静脉分流。在复发性肿瘤中不易检测到血流; 7个肿瘤中有2个呈弱阳性。彩色多普勒显示作为辅助超声成像在乳腺病变的鉴别诊断的承诺。
The color Doppler signals in 60 patients with breast masses were assessed subjectively, and a regional grading method was developed for quantitation of displayed blood vessel density. Among 21 patients with breast carcinoma, moderate or high flow was demonstrated in all but one, with an average of 0.5 vessels per square centimeter and color pixels occupying 12.2% of the image area. Among 33 patients with benign disorders, no flow was demonstrated in 25 and slight to moderate flow was seen in five, with an average of 0.01 vessels per square centimeter, occupying 0.8% of the image area. Cancers as small as 10 mm in diameter were positive for flow. High-velocity flow was seen only in malignancies; it was observed in four cases and may have been due to arteriovenous shunting. Flow was less readily detected in recurrent tumors; two of seven tumors were weakly positive. Color Doppler shows promise as an adjunct to ultrasound imaging in the differential diagnosis of breast lesions.
