摘要
本文对61例68个乳腺肿块进行了彩色Doppler血流显像(CDFI)及脉冲Doppler(PD)的检测,其中乳癌22例,良性肿块39例,均经手术和病理证实。结果表明:CDFI能迅速显示乳腺肿块的血流形态和分布,PD可区分动、静脉血流,在CDFI引导下进行检测可避免单纯PD检测的盲目性。动脉血流在21例乳癌和6例乳腺良性肿块中获得,而乳癌的血流阻力指数(RI)均大于0.55.彩超及频谱(双功彩色)Doppler超声诊断乳腺肿块的总符合率可达97.1%,高于灰阶超声诊断。因此,Doppler超声对乳腺肿块性质的判断是有价值的。
cases with 68 breast masses were detected by color Doppler flow imaging and pulsed Doppler.22 cases were breast cancers and 39 cases were benign lesions.All cases were proved by operation and pathology.The state and distribution of color Doppler flow in breast masses were displayed rapidly.The arterial flow and venous flow were differentiate by pulsed Doppler.Under the guiance of color Doppler flow image,the blindness which detected only by pulsed Doppler were be avoided.The arterial signals were detected in the 21 cases of breast carcinomas and 6 cases of breast benign lesions.The resistant indexes (RI) of flow in the breast cancers were over 0.55.The diagnostic accuracy of the duplex color Doppler ultrasound in the breast neoplasmas is 97.1%, it is higher than two-dimensional ultrasonography.There is very helpful using by Doppler ultrasound in the differential diagnosis of breast neoplasms.
