弹性成像中乳腺实性结节的蓝绿红分层现象李建民;任卫东【摘要】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 fi-broadenoma;2 intraductal papilloma) were diagnosed in 30 patients. The most common US findings showed an oval shape (82%, 28/34), parallel orientation (94%,32/34) and with circumscribed margin (94%,32/34). 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.%目的描述弹性成像中乳腺实性结节的蓝绿红分层(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,彩色多普勒成像(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;良性痛变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(82%,28/34),平行生长(94%,32/34),边界清楚(94%,32/34),并且所有病例均内呈低回声.结论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.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).【期刊名称】《中国医科大学学报》【年(卷),期】2013(042)002【总页数】4页(P168-171)【关键词】乳腺;实性结节;伪像;弹性成像【作者】李建民;任卫东【作者单位】中国医科大学附属盛京医院超声科,沈阳110004【正文语种】中文【中图分类】R445.1乳腺疾病的超声检查主要依赖常规灰阶超声和彩色多普勒技术,近几年发展起来的弹性成像技术是对传统超声检查的一个重要补充,有着良好的应用前景。
