Re: Yolk sac From: Edward Lyons (lyonsea@hotmail.com) Thu Jan 28 15:44:36 1999 Messages sorted by: [ date ][ thread ][ subject ][ author ] Next message: dr. amit sengupta: "Re: Yolk sac" Previous message: DuBose, Terry: "Re: Fetal Cerebral Ventricles" Our data was based on inside measurement. If you want to change the way it is measured then you have to redo the study. Seeing and measuring the inner diameter is simple to do as you all agree. We have found cases where everything looks normal except there is an abnormally large sac... and ultimately the fetus does not survive. That is why we measure it routinely... as an early indicator of potential problems.

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.
