Stationary and moving mammography grids: comparative radiation dose.
Mammography without a grid and with both a stationary and a moving grid was performed on 46 women. Mean gland dose to the breast was increased two to four times using either grid. Grid lines were apparent on films obtained with a stationary grid, but were not seen on those obtained with a moving grid. Although the radiation dose is the same with both grids, differences in the design of the two devices may lead to a personal preference in deciding which grid to use.
