Although rare, DXA is occasionally performed on pregnant patients for the diagnosis or the differential diagnosis of pregnancy-associated osteoporosis. Pregnant patients receiving heparin may require BMDa estimation. The maximum conceptus dose during the first trimester associated with DXA performed using a pencil-beam device was found to be 0.0034 mGy related to the scan of the hip [39]. In this study, conceptus doses from DXA performed during late pregnancy were found to be up to 0.0049 mGy. The highest dose was recorded for spinal imaging carried out during the third trimester of gestation. According to the ICRP, a dose to the conceptus below 100 mGy should not be considered a reason for terminating a pregnancy [40]. Because radiation dose to the unborn child from DXA is always less than 100 mGy, termination of pregnancy based on radiation risk is not justified. Although radiation dose to the conceptus is very low, DXA examinations on pregnant patients should be performed only when the expected benefits clearly exceed the reasonably suspected risks. When DXA is considered justified, the patient should be counselled before imaging on the actual dose received by the conceptus and the radiation risks involved.
