摘要
使用10MHz高频探头与彩色多普勒检查乳腺癌患者36例,所有病例均为手术及病理证实。36例患者中对侧乳腺均正常且作为对照组与患侧进行对比检查。结果表明乳癌患者中患侧乳腺的血管数目、血管分布以及血流量均明显高于正常侧乳腺。乳癌患者彩色多普勒血流显像(CDFI)的特点为:多呈环绕、伸入性五彩血流;部分呈湍流频谱;92%的癌瘤阻力指数(RI)>0.70。而正常乳腺RI均<0.69。以上特点能明显地提高乳腺癌诊断率。
36 patients with unilateral breast carcinoma were examined by 10 MHz high frequenc probe and color Doppler.All contralateral healthy breasts in these patient were compared with the diseased ones.We found that the number and distribution of blood vessels and blood flow in the breasts of carcinomas were higher than those in the healthy ones.The color doppler flow imaging of breast carcinomas are characterized with surrounding,penetrating and much color flow and turbulent flow spectra.The carcinomas of 92 percent are RI>0.70.The healthy breasts of 100 percent are RI<0.69.The characteristics mentioned above are very important to raising the diagnostic rate of breast carcinoma.
