[摘要] 目的：探讨彩色多普勒血流成像(CDFI)对乳腺良恶性肿块的诊断价值。方法：用CDFI对经病理证实的218例乳腺实质性肿块进行超声检查，并与病理结果进行对照分析。结果：218例肿块经病理诊断，178例(81.7%)为良性肿块，40例(18.3%)是恶性肿块。超声检查与病理诊断良性肿块的符合率为92.7%，恶性肿块的符合率为85.0%。良性肿瘤中以均匀低回声为主，周边可伴有包膜回声，形态较规则，无钙化灶，内部无血流信号或可见少许彩色血流信号，较大纤维瘤内可见丰富的彩色血流信号。恶性肿瘤形态不规则，边界不清，边缘呈多角形或蟹足样，内部多呈低回声，无包膜，肿块内出现形态不一，呈细点状、斑片状、团状、条状、线状，以细点状多见的钙化灶。良性肿块、恶性肿块的血流阻力指数分别为0.60±0.05、0.74±0.07，两者比较，差异有统计学意义(P<0.05)。结论：彩超对鉴别乳腺良恶性肿瘤有很好的临床应用价值。

[Abstract] Objective: To evaluate color Doppler flow imaging (CDFI) of benign and m alignant breast tumor diagnosis. Methods: 218 pathologically confirmed cases of breast solid mass were detected by CDFI, and results were compared with pathological analysis. Results: 218 cases of pathologically diagnosed, 178 patients (81.7%) were benign, 40 patients (18.3%) were m alignant tumor. Compliance rate between ultrasonography and pathological diagnosis of benign tumors was 92.7%, in line with m alignant tumors was 85.0%. Benign tumors showed mainly a uniform low echo, associated with echo around the capsule, which form was regular, no calcification, no blood flow or visible within a few color Doppler signals, the larger fibroids could be seen the rich color flow within the signal. M alignancy were irregular, ill-defined, polygonal edges or crab-like, mostly within the low echo, no capsule, the mass appeared in different form, was fine point-like, patchy, tangled, strip, linear, more common in fine punctate calcification. Benign and m alignant tumors of the blood flow index were respectively 0.60±0.05, 0.74±0.07, both had significant differences (P<0.05). Conclusion: Color Doppler has good clinical value in differentiating benign and m alignant tumors.

近年来乳腺疾病的发病率逐年增高，严重危害中老年女性的健康，其中乳腺癌占我国妇女恶性肿瘤的第2位。早期发现、早期诊断、早期治疗是延长寿命的关键。随着超声技术的不断发展，彩超在乳腺肿块诊断中的价值越来越得到肯定[1]。现回顾性总结218例乳腺实质性肿块患者的二维超声及彩色多普勒血流成像(color Doppler flow imaging，CDFI)的检查结果，以探讨彩超对乳腺肿块的诊断价值。
