Re: Lawson: AIUM says thousands of Fetal Photo Places !!!!From: Terry J. DuBose (duboseterryj@uams.edu)Mon Oct 28 13:11:25 2002
Good points... I wonder how much difference there is in fetal tissue density? Would this not be accounted for by regression analysis based upon volumetric measurements? We aren't dealing with weight lifting fetuses on steroids here. I would think that the age-liver-volume might be a fairly good predictor of overall tissue density... in addition with the abdominal, long bones and cranial volumes we might arrive at some better estimates of weight, ages, and fetal condition (TORCH infections). If there really is much difference in the fetal tissue density, then more measurements could increase the error. But Hadlock found that more measurements (up to 4) did increase accuracy. We are just in the infancy of sonography... 25-30 years of general use and equipment development is not much... it will get better. Peace, Terry J DuBose, M.S., RDMS

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.
