What scanning resolution do you think it's sufficient to obtain a reliable mesearument?

In our hospital we are begining to use this method. The biochemistry of the second trimester has been in use for two years, with poor to fair results, so far. It takes time to implement this kind of programmes.

Do you use the saggital plane of the embryo? What about false negatives results?

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
