BI-RADS分级在彩超检查乳腺良、恶性肿瘤中的规范化应用

The value of color Doppler ultrasound in breast tumor BI-RADS classification

目的:通过彩超检查手段,探讨BI-RADS分级在乳腺肿瘤中的规范化应用及其价值。方法:回顾性分析多例经手术、病理证实的乳腺良、恶性肿瘤患者的超声表现及彩色多普勒血流特点,重点是恶性肿瘤及交界性肿瘤的界定,规范其诊断时的应用标准。结果:经手术及活检病理诊断,经过术前BI-RADS分级方法筛查,超声诊断符合率为89.5%,其中误诊为良性54例(6.2%),误诊为恶性36例(4.2%),主要是4级(a,b,c)结节的鉴定存在误诊及偏差。结论:乳腺恶性肿瘤在声像图中的可疑征象:形态不规则、边缘不光整、高回声晕、垂直生长、后方回声衰减、瘤体内微钙化、血供丰富,其中形态不规则、边缘毛刺、边缘成角、肿瘤内微钙化为预测恶性肿瘤的主要指标,其余改变可作为次要指标。通过对上述指标的合理应用,使用统一的专业术语、标准的诊断归类及检查程序,达到早期、准确的诊断乳腺疾病尤其是恶性肿瘤。

Objective：To investigate the specification of BI - RADS grading in breast disease application. Meth- ods：Retrospective analysis was performed on breast benign and malignant neoplasms, examined by color Doppler flow characteristics. Results：Operation and pathological biopsy diagnosis and preoperative BI - RADS classification meth- od, ultrasound diagnosis coincidence rate was 89.5% , among them 54 cases misdiagnosed as benign（6.2% ） ,36 ma- lignant cases were misdiagnosed （4.2%）. Conclusion：Suspicious signs of breast cancer includes irregular shape,the edge is not smooth, hypereeboic halo, vertical growth, posterior echo attenuation, intratumoral calcification, abundant blood supply, the micro calcification of irregular shape, edge burr, edge angle, these are the main index to predict ma- lignant tumor.
