超声像素亮化处理技术在乳腺良恶性肿块诊断中的应用价值

目的 评价超声像素亮化处理技术(pure brilliance imaging,PBI)在乳腺良恶性肿块诊断中的应用价值.方法 对97个乳腺肿块分别使用高频超声和PBI进行术前检查,并与术后病理结果对照.结果 高频超声检查诊断的敏感性、特异性和准确性分别为77.8%、69.2%、73.2%,应用PBI后,乳腺肿块毛刺状边缘、"晕环"及钙化的检出率较高频超声检查明显提高(P<0.05),诊断的敏感性、特异性和准确性分别为91.1%、82.6%、86.6%.结论 超声PBI可明显提高乳腺肿块超声图像边缘特征的检出率,有助于乳腺良恶性肿块的鉴别诊断.

Application of pure brilliance imaging in diagnosis of benign and malignant breast neoplasms

Objective To evaluate the application of pure brilliance imaging(PB1) in diagnosis of benign and malignant breast neoplasms. Methods Ninty-seven breast neoplasms were respectively examined by high frequency ultrasound and PBI before operation,then correlated with pathological results. Results The accuracy of high frequency ultrasound for breast neoplasms was 73.2% with the sensitivity 77.8% ,specificity 69.2%. The detectable rate of spiculate margin, halo,calcification were much higher in PBI than those in high frequency ultrasound(P<0.05). And the accuracy,sensitivity and specificity of PBI were 86.6%, 91.1%, 82.6%. Conclusions PBI can significantly increase the detectable rate of ultrasonographie marginal features of breast neoplasms which were also helpful to the differential diagnosis.
