Table 3. Reading time for 2D and 2D+3D mammography by three radiologists and the average screen-reading time (data are shown both per screen read and for total screens).
| Radiologist |

| Time based on (by modality and whether individual or total screens) | A | B | C | Average reading time |
| Results for time per individual screen-read (per test) | ||||
| 2D mammography | 25 s | 27 s | 46 s | 33 s |
| 2D+3D mammography | 80 s | 60 s | 90 s | 77 s |
| Absolute difference | 54 s | 33 s | 44 s | 44 s |
