彩色多普勒超声诊断乳腺良恶性肿瘤的临床评价

The Clinical Value of Color Doppler Ultrasound in Differentiating Benigh and Malignant Breast Tumor

目的研究彩色多普勒超声对乳腺肿瘤的诊断价值.方法使用彩色超声仪对198例患者253个乳腺肿块进行检查,评价彩色多普勒血流显像特征,并与病理结果对照.结果乳腺恶性肿块的血流较良性明显丰富,恶性肿块的PSV为(24.33±0.35)cm/s,RI为0.71±0.22;良性肿块的PSV为(11.28±0.39)cm/s,RI为0.57±0.11,恶性肿块PSV和RI值均高于良性肿块(P<0.01).结论彩色多普勒超声对诊断及鉴别乳腺良恶性肿瘤有重要价值.

Objective To assess the diagnostic values of color Doppler ultrasound in differenting benign and malignant breast tumour.Methods 253 of breast lumps in 198 cases diagnosed by color Doppler ultrasound and were verified by pathology after operation.All data were analyzed.Results There were plentiful blood flow signals in malignant breast lumps.the maximal blood flow velocity（PSV）and the resistant index（RI）of malignant breast lumps was（24.33± 0.35）cm/s and（0.71±0.22）,and benign lesions was（11.28 ±0.39） cm/s and（0.57±0.11）,respectively.The value of PSV and RI were significantly higher in the malignant lesions than those in the benign ones（P0.01）.Conclusion Color Doppler ultrasound has important diagnostic values in differenting benign and malignant breast tumour.
