彩色多普勒超声对小乳腺癌与乳腺增生结节的鉴别诊断价值

目的：探讨二维超声结合彩色多普勒对乳腺癌与乳腺增生结节的鉴别诊断价值。方法：回顾性分析病理已证实为小乳腺癌和乳腺增生结节肿块的二维声像图及彩色多普勒特征，肿块血流信号分类标准按Adler主观分类法，脉冲多普勒定量分析肿块收缩期血流峰值流速及阻力指数。结果：小乳腺癌和乳腺增生结节在二维声像图中均表现为边界不清，纵横比值>1、肿块表面呈角状突起、钙化灶、后方回声衰减，恶性肿块各项指标敏感度明显高于增生结节，两者差异有统计学意义（P<0.05）。乳腺癌内部血流显示率100%（46/46），血流分级以Ⅱ~Ⅲ级为主；增生结节血流显示率25%（18/72），血流分级以0~Ⅰ级为主。结论：二维超声结合彩色多普勒综合分析，可提高乳腺癌与乳腺增生结节的鉴别诊断率，具有较高的临床应用价值。

Differential Diagnosis Value of Color Doppler Ultrasound between Small Breast Cancer and Hyperplastic Nodule of Mammary Glands

Objective：To investigate the differential diagnosis value of 2D ultrasound and color Doppler which were utilized to diagnosis small breast cancer and hyperplastic nodule of mammary glands. Methods：2D sonogram and characteristic color Doppler of breast cancer and hyperplastic nodule of mammary glands were analyzed retrospectively. Separate criteria of tumor blood flow signal was Adler subjective grouping. SPV and RI of tumor were quantitatively analyzed by polse Doppler. Results：2D sonogram of small breast cancer and hyperplastic nodule of mammary glands all displayed obscure boundary, ratio in length and breadth >1, cornua on the surface of tumor, calcification focus and pone echo attenuation. Sensitivity of each index in malignant tumor was higher than in Hyperplastic nodule. There was statistical significance between small breast cancer and hyperplastic nodule of mammary glands（P<0.05）. Manifestation ratio of internal blood flow in breast cancer was 100%（46/46）and grades of blood flow were Ⅱ~Ⅲ. Manifestation ratio of internal blood flow in hyperplastic nodule was 25%（18/72）and grades of blood flow were 0~Ⅰ. Conclusion：If 2D ultrasound and color Doppler were utilized to diagnosis small breast cancer and hyperplastic nodule of mammary glands, the differential diagnosis radio would be elevated and 2D ultrasound and color Doppler would be higher clinical value to utilize.
