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

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 Ultrasonography. Results Among the 218 cases,82 patients with malignant tumour;136 with benign tumour 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 Uhrasonography, a simple and noninvasive method was used to determine the nature of breast tumout. it showed a higher accuracy rate at the breast tumour diagnosis and the differential diagnosis. It has great clinical application value. Key words: Color doppler ultrasonography;  Breast tumours;  Diagnosis;  Differential diagnosis
