Abstract
We conducted a preliminary study to compare computerized measures of breast parenchymal pattern (BPP) on full field digital mammogram (FFDM) and digital breast tomosynthesis (DBT). A set of 123 subjects who had corresponding clinical FFDM of the same breast was collected from our DBT database. In a retroareolar region on the CC view, texture measures including run-length statistics (RLS), region-size statistics (RSS), and power spectrum were extracted from both modalities. Correlation analysis was performed to evaluate the similarities of the individual BPP measures between FFDM and DBT. It was found that the Pearson's correlation coefficients for the individual BPP measures between the matched pairs of FFDM and DBT ranged from 0.02 to 0.61. Our results indicated that the BPP measures were different between FFDM and DBT in this limited data set.
