How long is the NT scan?

When I booked the appointment the lady said that the ultrasound was a 1/2 hour long.  I find that to be excessive.  How long would you say they were in there?  They just take the pics and the OB or radiologist does the measurements right?

    Depends on if baby cooperates.  A 1/2 hour sounds about right.

    half hour sounds right.

    1/2 hour seems right. They have to get a lot of detailed pictures and check for a lot of measurements. Mine was around that long.

    That sounds right.  Ours was longer due to the baby not cooperating.

    I agree with the pp. Mine was also about 1/2 an hour...

    half an hour doesn't seem that long while it's going on. they have a lot of measurements to take at different angles. watching your LO for that long is entertaining at least!

    Mine didn't go so quickly. Baby didn't want to wake up so after much prodding and bending they sent me out to lunch and I had to go back! So, mine was more like an hour total. They measure the nasal bone and they need at least 3 measurements of the nuchal fold and use the largest. So, if baby isn't in just the right spot ( I think she said laying on back and chin at a 45 degree angle) it can be difficult.

    My baby slept through the whole thing so it didn't take very long.  But yes, a half hour sounds about right.  Be prepared for your 20 week u/s that usually takes about an hour.

    We were in there about that long. Plus, I wouldn't complain about it being too long. It's fun to see what LO is up to. :)
