彩色多普勒超声在乳腺肿块的诊断及鉴别诊断中的作用

Significance of color doppler uitrasonography in diagnosis and differential diagnosis of breast tumours

目的探讨彩色多普勒超声对乳腺肿块诊断和鉴别诊断的作用，提高超声检查的准确率。方法通过彩色多普勒检查乳腺肿块的大小、形态、内部回声及血供情况，测量阻力指数（RI），对本院2005年1月至2008年12月，218例乳腺肿块的病例与其手术或穿刺病理诊断结果进行对照分析。结果218例乳腺肿块病例中、恶性肿块82例；良性肿块136例，良性肿块中，乳腺纤维瘤54例，乳腺增生性疾病（乳腺腺病、乳腺纤维囊性增生、乳腺纤维增生）76例，乳腺囊肿3例，乳腺导管内乳头状瘤5例，误诊11例，诊断符合率为95％。结论彩色多普勒超声对乳腺肿块性质判断，在乳腺肿块的诊断及鉴别诊断方面符合率较高，简便无创伤，具有较大的临床应用价值。

Objective To evaluate Color Doppler Ultrasonography in the diagnosis and differential diagnosis of breast tumours, and improve the accuracy of ultrasound examination. Methods An analysis based on 218 breast tumours cases of surgery or puncture pathology diagnosis in our hospital, during January 2005 to December 2008. Breast tumour size, shape,internal echo, blood supply, and resistance index （RI） were estimated by Color Doppler Uhrasonography. Results Among the 218 cases,82 patients with malignant tumour; 136 with benign turnout which include 54 patients with breast fibromatosis,76 with proliferative breast disease （breast adenosis ,fibrocystic breast hyperplasia, breast fibrosis） ,3 with breast cysts, 5 with breast intraductal papilloma, 11 with misdiagnosis, the diagnostic coincidence rate was 95%. Conclusion Color Doppler Ultrasonography, a simple and noninvasive method was used to determine the nature of breast tumour, it showed a higher accuracy rate at the breast tumour diagnosis and the differential diagnosis. It has great clinical application value.
