摘　　要：报告５５例经手术病理证实的≤２０ｍｍ的乳腺小肿块的高频声像图及彩色多普勒和脉冲多普勒检查结果。其中小乳癌３１例，良性肿块２４例。文中分别对良恶性肿块的形态，边界，内部回声，反差大小，后方回声，侧方声影，纵横比，周边血流，内部血流以及肿块内小动脉Ｖｍａｘ值，ＲＩ值等多项指标进行对比分析。结果显示：良恶性肿块在以上各两维超声指标中都有显著性差异；在彩色多普勒和脉冲多普勒血流检出率及ＲＩ值方面亦有显著性差异。但是，脉冲多普勒在肿块内检出的Ｖｍａｘ值比较二者无显著差异。肿块内微钙化点的检出率比较，二者亦无显著差异。本组超声对小乳癌的敏感性为９６．８％（３０／３１），特异性为８７．５％（２１／２４），准确性为９２．７％（５１／５５）。This paper describes high frequency ultrasound, color Dopple ultrasound, and pulse Doppler ultrasound manifestations of 55 patients with small mammary tumor (≤20 mm). Diagnosis was confirmed by pathology in these 55 patients. Thirty one patients suffered from mammary cancer, and twenty four patients were ill with benign tumor. The sensitivity for malignant versus benign disease was 96.8%(30/31), with a specificity of 87.5%(21/24) and an overall accuracy of 92.7%(51/55). The authors suggest that the contrast on the ultrasonogram may be regarded as one of the indexes to differentiate the benign mass from the malignant tumor. There was higher mean (±s) length-breadth ratio in the malignant tumors than that in the benign masses (0.83±0.14 vs. 0. 71±0.16, P<0.05). The signal of blood flow increase was more common in the malignant tumors than in the benign masses(77.4%vs. 37.5%, P<0.005). There was no difference between the malignant tumors and the benign masses in the peak value of the small arterial blood flow rate and in the finding rate of the calcification particles.
