Participants
The survey was completed by 10,983 of the 18,225 participants (60%). In total, 39% reported DBT as not being painful at all (compared to 27% for DM), and 52% only some (compared to 46% for DM). No or some discomfort was experienced by 93% (compared to 76% for DM), and 97% reported no anxiety at all (compared to 88% for DM) (Table 1). The average pain score was 3, which was lower compared to the average score the participants reported for their previous DM (average 3,5) and lower compared to the current DM in the reference group (average 4,3) (Figure 1). In addition, 13% scored their pain with DBT screening at 0, compared to 9% for previous DM and current DM. Severe pain (score between 7 and 10) was reported by 13% for DBT, 17% for previous DM, and 29% for current DM. About half of the participants (52%) preferred DBT over DM, and 46% had no preference, mainly because they experienced no difference (Table 2). Moreover, 98% had the intention to participate again in future DBT screening.



Screening radiographers
The survey was completed by 62 of the approximately 100 radiographers (approximately 60%). In total, 84% of them reported DBT as ‘feasible’, and 16% reported DBT as ‘feasible, but sub-optimal’ (Table 3). Among radiographers, 16% preferred DBT over DM, 34% preferred DM, and 50% had no preference. The majority reported working with DBT to be very similar to the current situation with DM. Suggestions for improvements were directed at improving image loading time at the acquisition workstations.

Screening radiologists
The survey was completed by 25 of the 35 radiologists (71%). In total, 16% reported reading DBT in screening to be ‘feasible’, 76% reported it to be ‘feasible, but sub-optimal’, and 8% reported it to be ‘difficult to work with’. Comparing DBT imaging to DM priors was reported ‘feasible’ by 74% of the radiologists, ‘feasible, but sub-optimal’ by 17%, and ‘difficult to work with’ by 9%. Among radiologists, only one radiologist (4%) preferred DBT over DM, 72% preferred DM, and 16% had no preference. Suggestions for improvements were mainly focused on improving loading and reading times.
