彩色多普勒血流成像和频谱多普勒超声对乳腺良、恶性肿块的临床鉴别诊断价值

The clinical value of color Doppler flow combined with spectral Doppler mapping in differential diagnosis of breast malignant and benign tumors.

目的探讨彩色多普勒血流成像和频谱多普勒超声对乳腺良、恶性肿块的诊断和鉴别诊断价值。方法采用彩色多普勒检查244例乳腺肿块(良性120例,恶性124例),观察肿块内血管形态,数目与血流分布部位,获取滋养动脉血流频谱后,测定收缩期峰值流速(Vmax),最小舒张期流速(Vmin),阻力指数(RI)与脉动指数(PI)。结果本组244例乳腺肿块中检出有血流信号者128例,检出率为52.45%,其中良性肿块22例,检出率18.33%,恶性肿块106例,检出率85.48%。良性肿块组:阻力指数为(0.55±0.15);脉动指数为(1.18±0.17)。恶性肿块组:阻力指数为(0.80±0.17);脉动指数为(1.78±0.46)。两者间差异有统计学意义(P<0.01)。结论彩色多普勒血流成像与频谱多普勒超声能够提供乳腺良、恶性肿块的诊断和鉴别诊断的有限血流信息,可作为二维灰阶超声检查基础上的一种补充检查方法。

Objective To explore the value of the color flow mapping combined with spectrum morphology in diagnosis of benign and malignant breast tumors. Methods 244 cases of breast masses （ 120 cases of benign tumors, 124 cases of malignant tumors ） were analysed by color Doppler ultrasound, Observed blood vessel shape, number and distributing place of blood flow. Gained artery blood flow spectral, determined systole maximum velocity （ Vmax ）, diastole minimus velocity （ Vmin ）, resistant index （ RI ）, Pulstive index （ PI ） . Resuits Blood flow signals within the tumor were observed in 244 cases breast masses 128（52.45 % ）, benign tumors 22（ 18.33 % ）, malignant tumors 106（85.48% ） .The benign cases ： RI（0.55 ± 0.15） ,PI（ 1.18 ± 0.17） ;the malignant cases： RI（0.80 ± 0.17）. PI（ 1.78 ± 0.46 ）. Statistics difference is prominence in both（ P 〈 0.01 ）. Conclusion Color flow mapping combined with spectrum morphology help to diagnosis and differential diagnosis in breast malignant and benign tumors,it can but regarding supplement for two-diamensional ultrasound.
