something is wrong with either the software or the interpretation. according to Hadlock "Radiology" 181:129 - 133, 1991 article entitled "In utero analysis of fetal growth: A sonographic weight standard," an EFW of 2900 gm would be in approximately the 12th percentile for a gestational age of 39 wks. His table is similar to Williams California birth weight table published in the 80's.

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.
