    Abstract
  •   Objective  To investigate the quality of image and the radiation dose in different exposure mode by mammography, so as to summarize the most suitable exposure mode and exposure parameters in different patients.  Methods  Retrospective analysis clinical data of 90 female mammography patients and 12 phantoms (MPW- 01) in Nanfang Hospital from May to December 2020 were collected, dividing into two groups as patients group and phantoms group. The technical parameters, average glandular dose and image quality score with high contrast mode (CNT), standard mode (STD) and low dose mode (DOSE) of the two groups were compared and summarize the most suitable exposure mode and exposure parameters in different patients were summarized.  Results  The image quality of patients at different exposure mode was no significant difference, but the DOSE mode have the lowest dosed (0.99±0.18 mGy); secondly STD mode increased about 22.2% (1.21±0.18 mGy), and finally CNT mode increased about 108% (2.06±0.42 mGy). Phantoms in different exposure mode, have the lowest dosed in DOSE mode (about 0.9 mGy); secondly STD mode increased about 50% (1.35 ± 0.01 mGy); and finally CNT mode increased about 127% (2.05±0.01 mGy). The different exposure modes of phantoms was statistically different between in fiber and mass lesions. CNT mode was the best mode which can display the two kinds of lesions, the second was the STD mode, and the last one was DOSE mode.  Conclusion  On the premise of guarantee the quality of image, the optimal exposure combination can be selected as much as possible based on the glandular condition of the subject, in order to reduce the radiation dose of client, reinspection rate and recall rate.
