| 中文摘要: |
| 本文报告经手术及病理证实直径≤2.0cm的乳腺肿物61例,计73个病灶的彩色多普勒（CDI）超声检查结果。其中,恶性病变39例,计43个病灶；良性病变22例,计30个病灶。提出了我们的CDI半定量分型标准（CDI-HQA）:Ⅰ型:病变区0～1处探及浅淡小点状血流信号,多单色、无彩色混叠现象,且血流信号主要出现于病灶周边部。Ⅱ型:病变区1～2处探及较亮点状,细条状血流信号,可有彩色混叠现象。血流信号以周边为主,偶见伸入病灶实质内。Ⅲ型:病变区3处以上探及明亮粗大点状和/或条状、树枝状血流信号,且病灶周边和实质内均易探及,并常有彩色混叠现象。我们将病灶血供属Ⅱ～Ⅲ型者,Vmax≥0.20m/s和RI≥0.70作为恶性肿瘤的阳性诊断指标；提出将其中二项以上指标呈阳性表现者作为小乳腺癌的诊断标准。 |

| Color Doppler Imaging (CDI) studies were performed on 61 cases with 73 small breast lesions (≤2.0cm),including 43 malignant and 30 benign lesions with pathological confirmed.Our result showed:Combining color Doppler imaging half quantitative analysis (CDI HQA) which the lesion blood supply belong to Ⅱ～Ⅲ type,if RI≥0.70 and or Vmax≥0.20m/s is regarded as a criterion for the diagnosis of malignant lesions,the sensitivty,spcificity and accuracy were 90.7%,90% and 90.4%,which were higher than analysis of the single CDI HQA and RI or Vmax ( P <0.01).It was shown that combined analysis of CDI was more objective and accurate for diagnosis of the small brease cancer. |
