Radiation in Pregnancy with Dr. Polsinelli
Radiation effects can be deterministic or stochastic.
- Deterministic effects cause direct cell damage (radiation burns, teratogenicity, intrauterine death, genetic material damage). There is no evidence of teratogenicity in diagnostic testing radiation ranges (<50mGy). Genetic damage (causing effects in future generations) is theoretical and has not been reported. IUD is a concern, but on a population based scale there was no noted increase in incidence of fetal demise after large scale radiation event and this cannot be studied in vivo.
- Stochastic effects increase the probability of developing cancer. There is no minimum threshold and increasing dose increases probability. Risk of cancer noted to be ~5% if exposed to 1Gy of radiation. (for comparison maternal radiation is: chest xray = 0.1mGy; CT abd/pelvis 10mGy)
Radiation in Pregnancy
In the first of two posts preparing for Grand Rounds in the coming week, PGY-1 EM resident, Dr. Polsinelli, guides through the murky waters of radiation exposure during pregnancy. She offers a background on what radiation is, how it's measured, the effects of radiation on the fetus, and radiation doses associated with common diagnostic exams.
