【摘要】：目的评价超声造影特征及定量分析联合应用对乳腺病灶的诊断效能,及其与MRI的比较研究。方法 56例常规超声或钼靶上发现的BI-RADS 3~5类的乳腺病灶,进行超声造影和MRI检查。经两种方法检查的所有病灶均进行定量分析,并获得病理结果。比较两种影像学检查方法的诊断效能。结果乳腺超声造影诊断的灵敏度、特异度、准确度分别为89.7%、81.5%、85.7%;MRI诊断的灵敏度、特异度、准确性分别为96.6%、85.2%、91.1%。超声造影和MRI诊断结果的一致率为89.3%(50/56),两种诊断方法的诊断效能差异无统计学意义,且诊断结果的一致性好。结论超声造影能提供特征性的增强图像,为乳腺病灶良恶性的鉴别诊断提供丰富的信息。超声造影对乳腺病灶的诊断效能与MRI具有很好的一致性,是乳腺病灶诊断及鉴别诊断的一种有效的方法。
[Abstract]:Objective to evaluate the diagnostic efficacy of contrast-enhanced ultrasonography (CEUs) and quantitative analysis in the diagnosis of breast lesions. Methods 56 cases of breast lesions of BI-RADS 3 or 5 were found on conventional ultrasound or molybdenum target. Contrast-enhanced ultrasonography and MRI were performed. All lesions examined by both methods were quantitatively analyzed. The diagnostic efficacy of the two imaging methods was compared. Results the sensitivity, specificity and accuracy of mammography were 89. 7% and 85. 5%, respectively. The sensitivity, specificity and accuracy of MRI diagnosis were 96.6and 85.2and 91.1, respectively. The consistent rate between contrast-enhanced ultrasound and MRI was 89.3 / 56). There is no significant difference in diagnostic efficacy between the two diagnostic methods and the diagnostic results are consistent. Conclusion Contrast-enhanced ultrasound can provide characteristic enhanced images. Contrast-enhanced ultrasonography is consistent with MRI in the diagnosis of breast lesions and is an effective method for the diagnosis and differential diagnosis of breast lesions.

【正文快照】： 乳腺癌是女性最常见的恶性肿瘤,是导致女性死亡第二位的恶性肿瘤,其发病率随着年龄的增长而升高。一直以来,超声以其无创、简便的优点,成为乳腺病变诊断的首选方法。随着第二代超声造影剂声诺维的应用,乳腺超声造影(contrast-enhanced　ultrasound,CEUS)成为极具前景的诊断
