目的 :对不同病理类型的乳腺肿块进行血流特点的研究。方法 :患者术前行二维、彩色多普勒血流显像及脉冲多普勒检查 ,全部病例均经手术病理证实。分三组病理类型血流对照研究。结果 :囊肿仅 2个周边检出一处点状血流 ;纤维腺瘤与乳腺癌检出的血流形态分布不同 ;乳腺癌的 PSV及 RI均值较纤维腺瘤组高 ,两组间有显著性差异 (P <0 .0 1) ;乳腺癌灶≤ 2 cm与 >2 cm的 PSV及 RI均值两组间无显著性差异 (P >0 .0 5 )。结论 :纤维腺瘤与乳腺癌的 PSV及 RI有显著性差异 ,但其重叠性大。 RI≤ 0 .5 5 ,有助于排除乳腺癌的诊断。
Objective: To study the characteristics of blood flow in different pathological types of breast masses. Methods: The patients underwent two-dimensional, color Doppler flow imaging and pulsed Doppler before operation, all cases were confirmed by surgery and pathology. Divided three groups pathological type blood flow control study. Results: The peripheral blood flow was detected in only 2 peritubular cysts. The distribution of blood flow pattern was different between fibroadenoma and breast cancer. The mean PSV and RI of breast cancer were higher than that of fibroadenoma group (P <0.01). There was no significant difference between PSV and RI in breast cancer ≤ 2 cm and> 2 cm (P> 0.05). Conclusion: There is a significant difference between PSV and RI of fibroadenoma and breast cancer, but its overlap is large. RI ≤ 0 .5 5, helps to rule out the diagnosis of breast cancer.
