Table 2. Summary of Key Performance Measures for Screening with Tomosynthesis

Study [44] [45] [51] [52] [53] Overall 
CDR = cancer detection rate; DBT = digital breast tomosynthesis, also known as 3-D mammography; FFDM = full field digital mammography, also known as standard 2-D mammography; no. = number.
