The aim is to quantify fetal radiation exposure from clinical mammography and evaluate the need for pregnancy verification before the procedure.
Measurements were taken using a Hologic Selenia Dimensions system and an Alderson Rando Female phantom.
Air kerma was measured across different trimesters and imaging parameters, repeated thrice for accuracy.
Variability was assessed by repeating a setup after full reconstruction.
Mean fetal doses from mammography ranged from 0.048 µGy to 7.253 µGy across trimesters.
Dose increased with breast thickness, highest in the third trimester due to increased scatter.
Fetal dose remained significantly below levels associated with deterministic fetal effects.

Randomized trial quantifies fetal radiation dose in mammography, suggesting routine pregnancy verification may not be necessary.

Saarlemo et al. (2026) studied this question.
