【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。更多还原

【Abstract】 Objective:To evaluate color Doppler flow imaging(CDFI) of benign and malignant 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 malignant tumor.Compliance rate between ultrasonography and pathological diagnosis of benign tumors was 92.7%,in line with malignant 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.Malignancy 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 malignant 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 malignant tumors.更多还原
