A comparison of image quality and radiation dose between a cellular grid and a linear grid using a mammography phantom

In this phantom study, use of the cellular grid resulted in increased IQF with an acceptable increase in MGD under all exposure conditions tested with the largest improvement in IQF seen in the extremes of phantom thickness. This suggests that use of a cellular grid in clinical practice might help improve cancer detection rates, without breaching current radiation dose guidelines for accepted dose levels and be particularly beneficial when examining both very small and very large breasts.
