【摘要】 [目的]探讨乳腺良恶性肿块的高频超声图像和彩色多普勒血流检查(Color Doppler velocimeter,CDV)表现与其相关的病理特征,评估超声检查对乳腺良、恶性肿块的诊断价值。[方法]分析113例乳腺肿块的声像图特征及CDV表现与手术病理结果进行对照研究。[结果]乳腺良、恶性肿块声像图表现与病理改变有一定的关系。CDV检查中乳腺癌血流信号检出率97.80％,阻力指数RI=0.77±0.06;良性肿块检出率61.76％,RI=0.52±0.05,二者差异有显著性(P<0.01)。[结论]二维超声结合CDV诊断乳腺肿块符合率高,具有较高的临床使用价值。更多还原

【Abstract】 [ Objective ] To evaluate the significance of high-frequency ultrasonography (HFU) combined with color Doppler velocimeter (CDV) for the differential diagnosis of breast masses (BM) . [Methods] HFU and CDV findings in 113 cases of BM were compared with their pathological findings. [Results] There was a certain relationship between HFU findings and pathological findings. The detectable rate for the blood flow accounted 97.80% in breast cancer examined with HFU, resistance index (RI) being 0.77±0.06; detectable rate for benign BM was 61.76%, RI being 0.52±0.05. The difference was significant between the two detectable rates (P < 0.01). [Conclusion] HFU combined with CDV exerts a high diagnostic accordance rate for BM.更多还原
