Investigation of PE in pregnancy

We went over this in a recent teaching session with a radiology reg, with the conclusion that CTPA and CXR + V/Q perfusion only (Q) study have similar accuracy and radiation dose to the foetus, but the V/Q route has less radiation on the breasts (at a time of heightened sensitivity).

This was borne out in another brief review:

And from the Lancet in 2010: Bourjeily et al, PE in pregnancy
