常用乳腺影像诊断方法的比较研究

The comparison study of breast imaging diagnostic methods in common use

目的比较和评价彩色多普勒超声、钼靶和近红外线在乳腺癌及乳腺良性疾病诊断中的作用。方法以术后病理结果为金标准,比较术前3种检查方法的诊断准确性。结果共计565例乳腺疾病患者接受检查,其中乳腺癌274例,良性疾病291例。3种方法对乳腺癌的灵敏度、特异度和诊断符合率在76%～93%范围,其中彩超和钼靶在诊断符合率等指标上优于近红外线,尤其是≤2 cm的乳腺癌,近红外线对早期阶段乳腺癌有较高的假阴性率(48.8%)。对乳腺炎性病变和导管瘤,彩超有更好的灵敏度和准确性。无物理查体配合诊断的近红外线,其对乳腺癌的灵敏度和诊断符合率明显下降。结论彩色多普勒超声和钼靶是有价值的乳腺影像诊断方法。

Objective To compare and assess the accuracy of color-doppler uhrasonography, mammography and near-infrared light scanning in breast disease. Methods The diagnostic accuracy of the three methods were analyzed on the basis of post-operation pathological results. Results 565 cases （ breast cancer 274, benign lesion 291 ） were examined. The range of the sensitivity, specificity and accuracy rate of the three methods for breast cancer is 76% -93%. Color-doppler uhrasonography and mammography are superior to near-infrared light in the accuracy rate, especially for those tumor size ≤2 cm breast cancers. Near-infrared light had a high false negative rate （48.8%） for early breast cancer. Color-doppler ultrasonography has higher sensitivity and accuracy rate for intraductal papilloma and inflammatory lesion of breast. The sen- sitivity and accuracy rate reduced while near-infrared light performed without physical examination obviously reduced. Conclusions Color-doppler uhrasonography and mammography are valuable breast imaging diagnostic methods.
