Supports lead shielding for fetal dose reduction in CTPA models; leaves open clinical validation in pregnancy.
Does lead shielding effectively reduce fetal radiation dose during CT pulmonary angiography in a phantom model?
Conventional lead aprons provide significant and effective shielding for the fetus during CT pulmonary angiography, though dedicated shields could further optimize protection and comfort.
Iball et al. (2008) studied CT pulmonary angiography during pregnancy. Lead shielding vs. Alternative materials was evaluated on Fetal dose variation as a function of shielding thickness. Lead shielding was accurately modeled and demonstrated to be an effective and practical material for reducing fetal dose during CT pulmonary angiography.
