Abstract:

Objective To analyze the factors influencing BI-RADS classification of breast density under mammography. Methods Six hundred and fifty-two patients who underwent mammography during January 2008 to October 2008 at the Haidian Maternal and Child Health Hospital were analyzed using American college of radiology(ACR) proposed breast imaging reporting and data system(breast imaging reporting and data system, BI-RADS) 2003 forth edition. The relationship between the mammary gland density rating and the menopausal status, body mass index(BMI)was assessed. ResultsThere were significant difference in BMI, menopausal status and the mammary gland density among the women of different BIRADS classification groups(P<0.01 for all these comparisons). Conclusion Abnormal mammographic findings were relatively more frequently seen in the premenopausal, high-BMI and high breast density women. For such population health education and regular health check-up are needed.
