高频彩超在乳腺肿块诊断中的应用价值

目的：探讨高频超声及多普勒技术对乳腺肿决的诊断价值。方法：对120例乳腺肿块患者的高频声像图及彩色多普勒血流做详细观察记录，并与病理结果进行对比研究。结果：乳腺良恶性肿块的二维声像图表现及彩色血流表现与病理对照均有不同的特征性表现，恶性肿块形态不规则，纵横径比〉1。多为不均匀低回声，内部可出现微小钙化，后方回声衰减及腋窝淋巴结转移，彩色多普勒显示血流丰富（Ⅱ-Ⅲ级），PSV及RI均较良性高。以此乳腺癌诊断符合率达90．3％。结论：高频彩超对乳腺肿块良恶性的鉴别较佳，其中二维声像图是基础，而血流丰富程度及频谱多普勒中多项指标的变化更有助于提高乳腺癌的诊断准确性。

Objective ： To evaluate the diagnostic role of high frequency ultrasonography （HFU） and CDFI for breast lumps. Methods ： 2D - ultrasound and color doppler flow image （CDFI）findings were compared with pathological study in 120 cases with confirmed breast lumps. Results：There were conspicuous differences between breast malignant and benign masses in 2D and Doppler ultrasonography imaging. The most malignant lumps in our eases had irregular shape, heterogeneous internal echo, longitudinal - transverse diameter ratio 〉 1, aeoustic shadowing and axillary lymph node metastasis, CDFI signals rich ,PSV and RI were higher than the benigno According this, the diagnosis rate of breast cancer was about 90.3%. Conclusion ：The color Doppler parameters are wonderful in differentiating malignant and benign breast masses,the basis way is 2D ultrasonography , the degree of blood abundance and many other indices can improve diagnostic accordance of breast cancer.
