Abstract Objective To investigate the dose level of direct digital mammography in Guangxi, explore the factors that influence the image quality and dose in direct digital mammography.Methods A survey was carried out on 160 cases of mammography exposure recorded from 4 medical facilities in Guangxi. The personal information, photography posture, breast compression thickness, exposure parameters and the average breast dose (AGD) were collected. ANOVA and non-parametric test were used to analyse the data.Results The mean value of breast compression thickness in the collected 160 mammography parameters was 42 mm, median was 43 mm,the mean value of AGD was 2.0 mGy,median was 1.5 mGy. Significant difference exists in difference breast compression thickness of AGD (F=20.036,P<0.05). Breast compression thickness increases, the higher of AGD. The mean value AGD of MLO was 1.99 mGy, and the mean value AGD of CC was 2.0 mGy.No significant difference in the AGD data was found between the craniocandal and mediolateral oblique (F=0.685,P<0.05).Conclusion The value of AGD in Direct Digital Mammography of Guangxi was hight. Breast compression thickness,different anode/filter combinations and photography conditions have effect on AGD. For the consideration of the abore factors, the dose of the subjects shonld be controlled after the lowest possible leved.
