The optimal time to modify standard imaging protocols to reduce radiation exposure to the pregnant patient and her conceptus/fetus is well before the radiologic examination is requested. It is best to create written protocols for all imaging of pregnant patients to avoid reactive, nonoptimal protocol adjustments by physicians attempting to reduce radiation exposures. Protocols devised for imaging pregnant patients can be developed to reflect accumulated experience, literature reviews, and respected medical points of view. When a conceptus/fetus dose estimation will likely be necessary following examination of a pregnant patient, the task can be facilitated by documenting relevant technique factors [14] and machine-recorded dose surrogates, e.g., kerma-area product (also known as dose-area product) and cumulative reference-point air kerma [15]. Alternatively, it might be advantageous to estimate dose to the patient’s pelvis using personnel monitors that are sometimes set aside for such periodic needs.
