Methods The mammography quality of 21 hospitals were investigated. The image quality of normal intensifying screen film combination was tested and compared with computerized mammography The filming positions and operating skills were studied Results The important mammography details that were displayed have low conformity with the diagnostic requirements, mainly due to non conformity of these equipment to the requirements The optimal pressure suitable for mammography of the Chinese women was around 12 kg Conclusion Necessary attention must be paid to the improvement of imaging features of these equipment The improved operating skills will greatly raise the detecting percentage of pathological changes of breasts
