• Abdominopelvic CT fetal doses are estimated at about 10-50 mGy. — Abdominopelvic computed tomography during pregnancy and the risk of congenital malformations: protocol for a nationwide population-based cohort study in South Korea
• Abdominopelvic CT doses are below guideline thresholds but much higher than other diagnostic imaging doses. — Abdominopelvic computed tomography during pregnancy and the risk of congenital malformations: protocol for a nationwide population-based cohort study in South Korea
• Clinical guidelines allow diagnostic ionising radiation during pregnancy only when maternal benefit outweighs fetal risk and no suitable alternative exists. — Abdominopelvic computed tomography during pregnancy and the risk of congenital malformations: protocol for a nationwide population-based cohort study in South Korea
• Chest CT, brain CT, and plain radiographs are each listed as delivering fetal doses below 1 mGy. — Abdominopelvic computed tomography during pregnancy and the risk of congenital malformations: protocol for a nationwide population-based cohort study in South Korea
• The evidence supporting the 100-200 mGy threshold is limited by older study designs, small samples, and reliance on animal data. — Abdominopelvic computed tomography during pregnancy and the risk of congenital malformations: protocol for a nationwide population-based cohort study in South Korea
• Existing guidance states that fetal radiation exposure below 100-200 mGy does not appear to increase congenital malformation risk, even during organogenesis. — Abdominopelvic computed tomography during pregnancy and the risk of congenital malformations: protocol for a nationwide population-based cohort study in South Korea
