摘要： 目的探讨乳腺癌高频彩超声像图表现及肿瘤内部、肿瘤边缘与周围腺体组织之间彩色多普勒血流状况对乳腺癌的超声诊断价值。方法对50例经病理证实的乳腺恶性肿瘤的高频彩超声像图进行回顾性分析,比较不同肿块大小的乳腺恶性肿瘤的内部及肿块边缘与周围腺体组织0.5cm范围内的血流参数。结果乳腺恶性肿瘤多表现为形态不规则,边界欠清,边缘呈锯齿状,内部以低回声为主且分布不均匀,多数病灶内有微小钙化点,多数后方回声衰减,肿块纵横径比>1,肿块内部及肿块边缘与周围腺体组织之间彩色多普勒血流分级多表现为丰富血流,RI≥0.7,并且这些参数与肿块大小有密切关系。结论乳腺肿瘤内部及肿瘤与周围腺体组织0.5cm范围内彩色多普勒血流状况对诊断乳腺癌具有较高的正确率,并且肿块越大,血流越丰富。其结合二维声像图表现,可显著提高乳腺癌诊断的准确率,具有较高的临床应用价值。

Abstract: Objective To explore the features of high frequent ultrasonic(FHUS) image and diagnostic value of color Doppler flow imaging(CDFI) on breast cancer.Methods The features of FHUS image were analyzed retrospectively on 50 cases of malignant breast tumors identified by histopathology.The blood flow parameters of the tumor from patients with different ages,tumor sizes and pathological types were compared.Results Most of the malignant tumors appeared as irregular shape and border,serrated margin,low level and uneven distribution of internal echo.Most of the tumors also showed micro-calcifications,attenuation of rear echo,and the rate of length/width>1.The color Doppler flow imaging grades near the tumors mostly showed abundant blood flow,with the rate of RI≥0.7,and these parameters had close relationship with tumor size.Conclusion The color Doppler flow conditions of breast tumor and the tissues 0.5cm around the tumor have high exactitude for detecting breast cancers.The larger the tumor size,the more abundant of the color Doppler flow.Combination with 2DUS imagines will enhance observably the diagnostic accuracy of breast cancer and then have highly applicable value in clinic.
