20 week anatomy EIF

Christie

Had my anatomy scan and was told there is an EIF. She said it’s most likely nothing to worry about but could be linked to Down syndrome. I went ahead and done the quad screen for peace of mind as there were no other issues.. since then I’ve been analyzing every picture I have to determine if there is a nasal bone and all of that... first pic is from 13+4 and second is 20+1. What is your experience with EIF and also can you spot the nasal bone?
