We compared the abilities of power and conventional color Doppler sonography to depict the vascularity of solid breast lesions and evaluated the usefulness of power Doppler sonography in differentiating between benign and malignant breast lesions.
One hundred two solid breast lesions (59 benign and 43 malignant lesions) were studied with power and color Doppler sonography. Power and color Doppler sonograms were retrospectively compared for the depiction of blood flow signals. Power Doppler images were also reviewed for the amount of Doppler signals, pattern of vascularity, and morphology of vessels. The sensitivity, specificity, and accuracy of the 2 techniques were calculated.
Compared with color Doppler sonography, power Doppler sonography depicted flow superiorly in 61 cases (60%) and equally in 41 cases (40%). On power Doppler sonography, the incidence of marked blood flow in malignant lesions (65%) was higher than that in benign lesions (39%). The pattern of vascularity was predominantly central (86%) and/or penetrating (65%) more often in malignant lesions than in benign lesions (51% and 34%, respectively). Branching (56%) and disordered vessels (42%) were seen more often in malignant lesions than in benign lesions (22% and 8%, respectively). The sensitivity, specificity, and accuracy in diagnosing malignancy were 64%, 76%, and 71%, respectively, for power Doppler sonography and 77%, 76%, and 76% for color Doppler sonography.
Power Doppler sonography was more sensitive than color Doppler sonography in the detection of flow in solid breast lesions. Although power Doppler sonography was not more effective in diagnosing malignant lesions, central and penetrating vascularity patterns and branching and disordered vessels seem to be helpful findings in predicting malignancy.
我们比较了能量多普勒超声和传统彩色多普勒超声描绘乳腺实性病变血管分布的能力，并评估了能量多普勒超声在鉴别乳腺良恶性病变中的作用。
对102个乳腺实性病变（59个良性病变和43个恶性病变）进行能量多普勒超声和彩色多普勒超声检查。回顾性比较能量多普勒超声和彩色多普勒超声对血流信号的描绘。还对能量多普勒图像的多普勒信号量、血管分布模式和血管形态进行了评估。计算了两种技术的敏感性、特异性和准确性。
与彩色多普勒超声相比，能量多普勒超声在61例（60%）中更清晰地显示了血流，在41例（40%）中显示效果相同。在能量多普勒超声检查中，恶性病变中血流丰富的发生率（65%）高于良性病变（39%）。恶性病变中血管分布模式以中央型（86%）和/或穿入型（65%）为主，高于良性病变（分别为51%和34%）。恶性病变中分支状（56%）和紊乱血管（42%）的出现频率高于良性病变（分别为22%和8%）。能量多普勒超声诊断恶性病变的敏感性、特异性和准确性分别为64%、76%和71%，彩色多普勒超声分别为77%、76%和76%。
在检测乳腺实性病变的血流方面，能量多普勒超声比彩色多普勒超声更敏感。尽管能量多普勒超声在诊断恶性病变方面效果并不更佳，但中央型和穿入型血管分布模式以及分支状和紊乱血管似乎有助于预测恶性病变。
