弹性成像中乳腺实性结节的BGR现象

 目的描述弹性成像中乳腺实性结节的BGR伪像。方法回顾性分析34例在弹性成像中出现BGR伪像的实性结节的超声表现，CDFI和结节的平均大小，结节距乳头距离，结节深度，乳腺腺体厚度等变量。结果30位女性患者的34例弹性成像出现BGR伪像的实性结节中恶性病变2例，病理类型为浸润性导管癌；良性病变32例，病理类型分别为乳腺腺病27例，纤维腺瘤3例，导管内乳头状瘤2例。这些实性结节最常见的超声表现是椭圆形(n=28, 82%)，平行生长(n=32,94%)，边界清楚(n=32,94%)，并且所有病例均内呈低回声。结论1.弹性成像中乳腺结节出现的BGR伪像并不仅仅提示可能囊性病变，也有实性可能，需要结合结节的二维声像图和CDFI特征做出准确判断。2. 弹性成像中出现BGR伪像的实性结节有良性可能，也有恶性可能，良性仍然为多数（32/34）。

Breast Solid Lesions with A Blue-green-red Pattern Artifact on Ultrasound-elastography

Objective To describe the aliasing artifact on us-elastography for breast solid lesions. Methods A total of 34 lesions which showed a blue-green-red pattern artifact on us-elastography were retrospectively reviewed. US findings and lesion variables were analyzed.Results A total of 34 breast solid lesions with a blue-green-red pattern artifact on US-elastography (2 IDC; 27 mammary hyperplasia; 3 fibroadenoma; 2 intraductal papilloma) were diagnosed in 30 patients. The most common US findings showed an oval shape (n=28,82%),parallel orientation (n=32,94%) and with circumscribed margin (n=32,94%). All 34 lesions were hypoechoic. Conclusion An aliasing artifact that appears as a blue-green-red pattern in breast lesions depicted on us-elastography is not only suggestive of a possible cystic breast lesion but also suggestive of a possible solid breast lesion. Majority of the solid lesions with a blue-green-red pattern artifact on US-elastography were benign (32/34),but also could be malignant.
