彩色多普勒超声诊断乳腺肿块性质的价值探讨

Evaluate the Diagnosing Value of Color Doppler in Breast Necplasm

目的:探讨彩色多普勒超声诊断乳腺肿块性质的价值。方法:应用彩色多普勒超声检查经手术和病理证实的肿块,其中良性肿块51例,恶性肿块25例。结果:①直径<2cm的恶性肿块彩色血流信号检出率(100%)高于良性肿块(11.7%)。②直径≥2cm的恶性肿块彩色血流信号检出率(93.6%)高于良性肿块(70.5%)。③当肿瘤直径<2cm时,良恶性肿瘤之间的临界动脉峰值流速为12cm/s,而静脉型血流频谱只在良性肿块内探及。结论:在直径<2cm的乳腺肿块内探及血流信号以恶性可能性大,彩色多普勒血流显像检查,可以提高乳腺恶性肿瘤,特别是2cm以下的乳癌的诊断率。

Objective: To evaluate the diagnosing value of Color Doppler in Breast Necplasm.Method:The Color Dop pler diagnosis was performed in 51 cases of benign breast masses and 25 cases of malignant confirmed by surgery and pathology. Results: ①The breast mass(φ<2cm) had a high risk of malignance if Color Doppler Signal was detected.(100%)②Detection rate of Color Doppler signal in benign mass(Φ≥2cm)was lower(70.5%)than that in malignant(93.6).③Critical peak velocity between malignant and benign breast mass was 12cm/s,and vein scmpectrum only can be detected in benign masses.Conclusion: Color of Doppler diagnosis can improve the detection rate of malignance(φ<2cm).
